Graph Drawing Tool Using Function
Rob Schultz
Excel has over 475 formulas in its Functions Library, from simple mathematics to very compound applied mathematics, logical, and technology tasks such as IF statements (one of our perennial favorite stories); AND, OR, Non functions; COUNT, Modal, and MIN/MAX.
The basic functions covered below are among the most common formulas in Excel—the ones everyone should know. To help you learn, we've also provided a spreadsheet with all the rul examples we cover below.
This spreadsheet contains a tab for each of the formulas covered in this story, with example data. JD Sartain
1. TODAY/NOW
There are 24 Appointment and Meter functions listed on the drop-down menu under Formulas > Particular date & Time: 11 Date formats, 10 Sentence formats, and as many user-defined custom formats you can create. The TODAY run reveals the current month, day, and year; piece the At present function reveals the prevalent month, day, year, and time of day. This is a handy function if you're one of those individuals WHO e'er forgets up to now your work.
1. Enter the favorable chemical formula in electric cell A1: =TODAY() and press Enter.
2. Next, type over that use in A1 with =Directly().
IMPORTANT NOTE: Wherefore type complete? Systematic for these two formulas to work properly, they must be entered in the Home cell, that is, A1, other than, they won't update automatically when the spreadsheet recalculates. Press Shift- F9 to calculate/recalculate the active spreadsheet only, operating theater press F9 for the entire workbook.
Afterward you enter one of these functions in A1, you can then reformat the Date and Time OR use the organization default. The default format for the TODAY function is 8/29/18, and the default for Straightaway is 8/29/18 21:57. If these get into't work for you, change them.
3. Put on your cursor along the Date Beaver State Time you want changed and choose Home > Format > Format Cells.
4. In the Format Cells dialog window, choose Date (or Clip) from the Category panel under the Number tab.
5. Roll through with the number of Particular date/Time formats in the Type dialog pane and select the data format that best fits your project.
JD Sartain / IDG Oecumenical 2. SUM functions
Probably the almost oftentimes used function in Excel (or any other spreadsheet program), =SUM does just that: It sums a column, row, OR range of numbers—but it doesn't just sum. It also subtracts, multiplies, divides, and uses any of the comparison operators to rejoi a result of 1 (admittedly) or 0 (false).
You can also get the same results just using the plus (+) check in place of the operate SUM. For instance, some of these formulas acquire the same answer: =Total(J7*9) and =+(J7*9). In the spreadsheet graphic at a lower place, notice that cells E3 through E8 use the SUM serve, while cells E9 through E9 through E14 use the plus (+) sign and the results are the same.
You can enter the Union function (or + sign) manually or select IT from the Ribbon menu under Formulas > Math & Trig (button), then choose from the drop-down list; or prefer (from the Ribbon carte) Formulas > Stick in Function, then scroll down the name and select it from there.
If you just want to tot a single chromatography column of numbers, position your cursor in the cell at the bottom of that column, sink in the AutoSum clitoris > Add up, and press Enter. Excel frames the column of numbers in green borders and displays the formula in the current cell.
JD Sartain / IDG Worldwide The trouble comes when the range of Book of Numbers you need to calculate gets complicated with multiple calculation operators over multiple cellsFor instance: =Join(H1+I1*J1-M1*J1. Think your high school math? If the numbers at heart the formula are not classified right, the answer will be wrong. Notice the screenshot under (figure 2).
Enter the following column headers in H2 through P2 (use AL+ Enter to stack headers in a single jail cell): Day-after-day Earnings, Summation Bonuses, Multiplication Years Worked, Total Pay, (formula), Minus Meals at $9.00 per day, Amount Monthly Salary, Formula, and Comment.
NOTE: The formula columns are FYI only and provide no inherent value to the spreadsheet. They just "display" the convention for your benefit (soh you can see the syntax of for each one formula used).
For this usage, you can enter the same values in H3:11, I3:11, and J3:11, with operating theatre without the blank rows in between (again, added for easier viewing). Double-dyed as follows: $86.00, $20.00, 22.0 workdays, and the breathe are formulas. Observe that Eastern Samoa we build each formula, we are combining the stairs, at length, into a one-on-one formula.
We part with with 3 separate formulas. The first is to add the Daily earnings, plus Bonuses, multiplied by the number of days worked in a calendar month, which equals Gross Pay: =SUM(H3+I3*J3) in cell K3. Notice that the answer is $526.00. That right doesn't look right.
Use of goods and services your calculator to ascertain the formulas to insure they'atomic number 75 castigate BEFORE you copy them to the roost of the cells in the column.
The expression in K3 is wrong. It requires pigeonholing the numbers according to the monastic order of calculation using commas or parentheses.
Take note the apochromatic formula in cellular telephone K4: =SUM(H4+I4)*J4. Check your numbers again (with your figurer) and annotation that this rule is correct. The correct suffice is $2,332.00.
5. The second formula (in M4) is =SUM(J4*9) multiplies the workdays (22) times $9.00, the cost of meals per solar day. The sort out answer is $198.00.
6. The third formula (in N4) calculates the each month earnings minus the meals: =SUM(K4-M4); answer is $2,134.00.
7. In the next grouping (H6:N8), the formulas in M6:M8 remain the same: =SUM(J7*9), etc.—over again that's the come of workdays multiplication the price of meals. But the formulas in column K are eliminated and then combined with the formulas in column M: =SUM(H7+I7)*J7-M7. Note that the syntax (the construction or layout of the chemical formula) is objurgate in cells N7 and N8, but incorrect in N6.
8. The future radical (H10:H11) combines the formulas in column M with the formulas in column N: =Gist(H11+I11)*J11-(M11*J11)—note that the formula in N10 is incorrect. By combining these formulas into one, you can extinguish columns K and L.
9. Also, instead of "hardcoding" the price of the meals (as shown in M3:M4 and M6:M8), you can at once change the damage of the meals in column M (M10:M11) when inflation dictates an increase as an alternative of changing the chemical formula.
JD Sartain / IDG Oecumenical 3. RAND function
The RAND function is genuinely simple and traditionally used for statistical analysis, cryptography, gaming, gambling, and probability possibility, among lots of other things. In Surpass, the RAND function generates a random number between 0 and 1. Note; however, that every time you enter new information and urge the Enter distinguish, the list of hit-or-miss numbers you sensible created changes. If you penury to maintain your random numbers lists, you must format the cells as values.
1. Enter the function =RAND() in columns A3 through A14. Select that column and press Ctrl+C (for copy) Beaver State click the Copy push under the Home tab and choose Copy from the deteriorate-down card. Move your cursor to cubicle B3 and choose Home > Library paste > Paste Specific. Click the Values push button from the Paste Special dialog window, then click O.k..
2. Nowadays the number contains values alternatively of functions, so it will not change. Poster (in the formula bar) that the random numbers pool have 15 digits after the decimal (Excel defaults to 9), which you can change, if essential (Eastern Samoa displayed in cell F3). Fair-minded click the Increase Denary button in the Number group under the Abode tab.
3. If you prefer to workplace with complete numbers racket, enter this formula in cell F3: =INT(RAND()*999) and you get a 3-digit random number. Copy the formula down through F12, then bring other '9' to the string to add another digit to your random number—e.g., four nines equal four digits, five nines equal five digits. Again, you must replicate the leaning and Paste As Values to maintain a static inclination.
JD Sartain / IDG Worldwide 4. COUNT functions
Practice the COUNT function to count the number of denotive values in a range of cells; for example: C4:C15 contains the quantity of garden tools Mr. McGregor of necessity to order for his shop. Government note that the answer is 10 (out of 12), because the COUNT mathematical function does not include blank cells. However, if you enter a zero, a numeric code, or a date, Excel counts it as an "occupied" cellular phone and includes it in its answer.
Enter 10 numbers into column C (Measure). Replace one number with a space (or a tap on the spacebar), then replace other number with a semicolon, then enter a date into cellular phone C7.
Introduce this chemical formula at the bottom of the list list (C16): =Weigh(C4:C15). The answer is 10 (out of 12) because Stand out counted all the numbers and the date, but ignored the vacuous cell (containing the quad) and the punctuation in cubicle C8.
Use the COUNTA run if you want to let in numeric values, logical operating room error values, text, a space (from the spacebar), punctuation, symbols, or any otherwise character on your keyboard.
1. Enter 12 dollar amounts into column D (Price). Supervene upon nonpareil cellphone with a question mark, another cellular phone with a symbol, and another cellular telephone with some text.
2. Introduce this rule in D16: =COUNTA(C4:C15). The answer is 12 (kayoed of 12) because Excel included all the "non-numeric" values and characters.
3. Notice that row 18 (C and D) displays the actual formulas that are in C and D 16.
JD Sartain / IDG Worldwide 5. Common function
Most everyone knows that an average is determined by adding all the values in a list, then dividing aside the number of values listed; e.g., 4+5+3=12/3=4, which is the intermediate. You stool use the SUM function and add the division completely in one formula, or you can just use the AVERAGE office. The syntax is: =AVERAGE(range).
1. Insert some numbers in column A. Enter the AVERAGE office at the bottom of the list: =AVERAGE(A4:A13) and banker's bill the answer (in our case) is 53. You can verify your answer with the SUM function; that is: =SUM(A4:A13/10) = 53.
2. Next enter some more numbers in column C merely, this time, add some text to single cellphone, punctuation to another, and a blank space to another. Enter the same formula: =AVERAGE(A4:A15), and greenbac the answer is 78. To avow, enter the Heart formula omitting the cells that moderate non-numeric characters:
Cells that contain text edition, discursive values, punctuation, or empty cells are forgotten; but cells with the zeros (as a number, but not as schoolbook) are included. A textbook zero would have an apostrophe ahead of the zero, which you cannot see in the cell, but is visible in the Formula Bar.
IMPORTANT Promissory note: If you're importing huge databases from a mainframe or an after-school, external rootage, sometimes the numbers exportation as text. How can you bed if a count is really text? Generally, textbook is left-even and numbers are right-even but, because everyone formats their spreadsheets for esthetics now, that method acting is unreliable. Another option is to scroll quickly through and through a aware name of imported numbers and watch the Formula Bar. If you see apostrophes before any of the numbers, those entries are text. Last, look to the green Triangle in the top left corner of the cell. Unless the previous owner of the spreadsheet instructed Stand out to disregard this error, and so the table of contents of the electric cell are text.
If the values are text, you must convert them to numbers pool immediately. To do this, move down to the first number in the heel that's actually text. Play up the reach of text that's impersonating numbers. Starboard-click the yellow warning bless that's left field of the archetypical textual matter cell in the reach. Click Convert to Total from the soda pop-up list, and information technology's done.
JD Sartain / IDG Worldwide 6. MIN/MAX functions
Use the MIN function to find the smallest issue in a range of values, and the MAX function to find the highest. The phrase structure for these functions are: =MIN(range); =MAX(range) where range equals the listing of numbers you're calculating.
Common uses of this function are; for exercise, find the highest/lowest plac in a classroom; the highest/last-place sales dollars in a store; the highest/lowest batting averages of your favorite baseball team; and so on.
Some would ask, why not just sort the data? You could, just all time the numbers changed, you'd suffer to re-variety. And, if you're sort multiple columns/fields with a lot of records/rows, the sort option could get cumbersome.
The MIN/MAX functions continue the same regardless of the changes in the information, even if you add more rows (as prospicient arsenic you add the rows using the Cut-in > Row feature within the existing range—that is, above the cell that contains the formula).
Enter some numbers in editorial A4:A11, then enter this formula in A13: =Amoy(A4:A11) and this chemical formula in A14: =MAX(A4:A11).
NOTE: The MIN/MAX functions disregard empty cells, Rightful/FALSE answers, text, text impersonating numbers, symbols, and punctuation mark.
Future in the lead, the powerful Concatenate function that combines multiple cells' worth of information! Keep reading for more swell formulas.
JD Sartain / IDG Worldwide 7. CONCAT/CONCATENATE
The functions CONCAT and CONCATENATE do the same thing: They both combine multiple cells, ranges, operating theater strings of data into one cadre. The most common use of this function is to combine above all key out into one cell Beaver State join the city, state of matter, and ZIP encipher into one cell.
NOTE: CONCAT replaced CONCATENATE in Excel 2022, but both functions are still available. Government note that CONCAT appears only under Formulas > Text and Formulas > Insert Function > Category > Text, only both CONCAT and CONCATENATE seem subordinate Formulas > Insert Subprogram > Category > All.
Inscribe some first gear names in column A and last names in column B. Enter the following chemical formula in newspaper column C: =CONCATENATE(A4," ",B4) or =CONCAT(B4," ",C4), then simulate the formula down. What are the double quotes for? See Note down the stairs #2.
2. Enter a some cities (or ski resorts) in column F, states in editorial G, and Null codes in column H. Recruit the followers recipe in column I: =CONCATENATE(F4, ",", " ", G4," ",H4).
NOTE: If you want a space between the first and concluding name, you must accede that blank space at heart quotation marks in your formula. The same thing is true for punctuation mark, such as a Polygonia comma betwixt urban center and state. In the followers formula the "," (quote comma quotation mark—in red) tells Stand out to insert a comma between the data in F15 (metropolis) and the information in G15 (state). The " " (citation space quote—in majestic) adds a space after the comma between F15 (city) and G15 (tell) and another space betwixt G15 (state) and H15 (speed up code).
=CONCATENATE(F15, ",", " ", G15, " ",H15).
JD Sartain / IDG Worldwide 8. TRIM
This function removes spare (or padded) spaces that infect your data American Samoa a result of exploiter error, downloading data from an external source such arsenic the Internet, or importation data from another computer system. And you don't have to "tell Excel" where the spaces are located in the string of text in all cell; IT recognizes the supererogatory spaces and removes them. Note; however, that it will non remove a space in the middle of a word. The syntax is simple: =Prune(cadre come up to).
1. Enter some information in column A. Add some spaces earlier, after, and in the middle of multiple words, then enter the following formula in cell A4: =TRIM(A4).
2. Copy the formula blue. It's that easy!
NOTE: There is one and only case where this function does not work, and that's with a not-breaking space character reference old in webpages. The decimal value is 160, and the HTML code is &ere;nbsp. You can remove this character using a combination of TRIM, Pure, and SUBSTITUTE.
JD Sartain / IDG Worldwide 9. UPPER/LOWER/PROPER
Another well-to-do group, these functions convert text edition in a cell or range of cells to uppercase, small letter Beaver State appropriate case. Proper case is first letter in caps and odd letters in lowercase. The syntax is simple: function, cell address.
1. Enter whatever mixed-case data in column A; e.g., Golden State, nEW York, spanISH. Enter the following formula in column B: =High(A4), in pillar C: =LOWER(A4), and column D: =Specific(A4).
2. Observance that Excel corrects all the misplaced case errors and converts the information correctly. Copy the formulas down, and that's it for this simple one.
NOTE: In Parole, you posterior use Chemise-F3 to cycle through uppercase, lowercase, and tight-laced case, but this shortcut important is not getable in Surpass. Note that the Excel function =PROPER is called Judgment of conviction case in Word.
JD Sartain / IDG Oecumenical 10. REPT
When Lotus 1-2-3 was the only game in town, you could enter a backslash followed by any character reference and Nymphaea lotus would repeat that character throughout a cell. If the cell width grew larger operating room little, so did the character. In Excel, this feature is handled by the function REPT. Information technology's not quite as efficient because you must add the character to the formula, then specify how many multiplication you want that persona repeated. This means if the cell width is increased, the repeated type is not, and if the prison cell width is decreased, the repeated character bleeds over into the adjacent cell.
The syntax for this function: =REPT("*",5); =REPT("—",10), =REPT("+",12). You prat repeat whatever character on the keyboard nonnegative symbols.
JD Sartain / IDG Comprehensive 11. IF statement
The IF function (also more usually called IF statements) work like this: IF, then, other. Basically, that means if a condition is true, and then do one affair, else/otherwise do something else. For example, if the puppy is a Labrador, then buy a blue catch, otherwise/else, buy a red collar.
The phrase structure (the room the commands are unionised in the formula) of the IF statement is: =IF(logic_test, value_if true, value_if_false). IF statements are used in totally programming languages and, although the sentence structure may vary slightly, this function provides the same results.
1. Enter the following newspaper column headers: Cookie Boxes Sold; 3rd Prize =More than 500 Sold-out, Less than 1000; 2nd Prize =Thomas More than 1000 Sold, Less than 1500; 1st Prize =Many than 1500 Sold, Less than 2000; Opulent Prize =More than 2000 Sold
2. Enter some numbers pool into newspaper column A4:A13. Mix it up so you get data altogether of the Sold columns.
3. Go into this formula in B4: =IF($A4>500, $A4, 0).
Observe the $ sign before the tower letter 'A' in the supra rule. Place your cursor connected the first 'A' in the chemical formula, then use the function key F4 to cycle through the Absolute and Relative References. Stop when the $ bless precedes the 'A' (for each A in the formula). This tells Excel NOT to change the tower alphabetic character, but only alteration the row numbers racket when this formula is copied. If you put a dollar subscribe before both the column letter and the row number, neither would alter.
4. Copy the formula in B4 to C4, D4, and E4, then edit As follows: C4 =IF($A4>1000, $A4, 0); D4 =IF($A4>1500, $A4, 0); and E4 =IF($A4>2000, $A4, 0). Then copy cut down.
5. The formula works, but you have to review each column to figure who North Korean won the prizes, because each newspaper column shows Entirely the values greater than the amount in the normal. That's ok for a small spreadsheet, but non for all the world larger than a single screen.
6. We indigence a Nested IF statement for this one. Repeat numbers racket 1, 2, and 3 to a higher place beginning on row 20; but instead of the expression in 3 above, enter this chemical formula in B20: =IF(AND($A20>500,$A20<1000),$A20,0).
7. Repeat bi 4 above, but edit the formulas like this: C20 = =IF(AND($A20>1000,$A20<1500),$A20,0); D20 = =IF(AND($A20>1500,$A20<2000),$A20,0); and E20 = =IF($A20>2000, $A20, 0). Yes, this last combined is different because there is no "less than" sum of money. And then re-create thrown. Now you can expect at each column and settle immediately who the winner is for that category.
JD Sartain / IDG WorldwideBasic IFstatements and nested IF statements 12. AND/OR
AND and Oregon are common functions in the programmers' environment, also referred to as Boolean operators (along with NOT). AND means that completely conditions in the enquiry must be true; OR means that at least single condition must be true.
E.g., looking for an applicant with MS Son AND MS Excel experience means the applier moldiness have both skills to qualify for the job. This condition would provide a TRUE issue. Looking for an applicant with Mississippi Word Operating room Stand out means the applicant must have ace OR the other, but not needs both. Also a TRUE result. Having neither skills would, apparently, provide a FALSE resultant role.
1. Copy the Numbers from the spreadsheet in project 13, or download the good workbook (link below).
2. Enter the shadowing AND formula in cell D4: =AND($B4>=501,$C4<=500). Again, note the $ signs. Then copy down to cell D13.
3. Enter this recipe in cell F4: =Surgery($B4>=501,$C4<=500), then replicate down. Notice the results in the rows with borders; that is, 5, 8, and 13. The AND results are all FALSE because both conditions were false (or not true); while the OR results were totally TRUE because one of the conditions was true, piece the else was false.
If this seems disorienting, subject field the numbers in columns B and C. Then read the formulas that figure out for the AND function, so the OR function, and it leave make more sense.
JD Sartain / IDG Worldwide 13. Non
Having explained to a higher place how the AND and Surgery functions (besides called Mathematician operators) work, the third Boolean hustler in that mix is the NOT function. Ever lookup finished a really long name of data and wish you could remove complete the entries that make Non put on? For case, I wish to see everything available about alternative get-up-and-go EXCEPT (operating theatre NOT) nuclear.
In Surpass, it's an well-heeled task. Create a name of 25 companies that provide assorted alternative DOE sources and what those resources are (columns A, B, C; set about on row 4). Get into the following formula in cell C4: =NOT(B4="Midpoint"). Then copy the formula from C4 down to C5:C28.
If the answer is TRUE, the energy source is NOT nuclear. If the response is FALSE, the energy source IS midpoint. Yes, IT's backward system of logic and you may not immediately see a need for this function but, if you're an avid Excel substance abuser, you will discover umteen reasons to use this pattern in the future.
TIP: Remember that Boolean logic applies throughout all database programs, including your favorite search engines. The Boolean operators AND and Oregon must be in all-caps to function Eastern Samoa an operator. In Google, the Boolean NOT wheeler dealer is the minus sign; for example, to inclination all alternative energy sources EXCEPT nuclear, type this in the hunt field box: list all mutually exclusive energy sources –nuclear.
Got text and numbers with delimiters all over the place? Keep reading for the formula to fix that.
JD Sartain/IDG Using the NOT Boolean operator
14. Powerful & Text-to-Columns
Imagine that your foreman just conveyed you a file with 100,000 name calling and addresses compiled from several data dumps off multiple different database systems, such as Oracle RDBMS, Tomfool Sybase ASE, Informix, MongoDB, Redis, and Couchbase. The filing cabinet is in a CSV (comma separate values) delimited format, so you can open information technology in Stand out, simply the delimiters are all over the place—some are commas, some are spaces, some are tabs, and thus on. Your job is to reformat the extend to-happening data into quintuplet fields: Name, Address1, Address2, City, and State.
A. First, unshared the urban center, put forward, and ZIP codes into different columns. Select column C (City, Express, Energy), then choose Data > Text to Columns. Ensure the Delimited button is restrained, past click Incoming. On the next screen, check that the Comma box is checked, and then click Next. Browse through the listing to secure the separation is correct, then sink in Finish. Excel divides the ace column into two.
B. Now we need to separate the ZIP codes from the state names. For this task, the Text to Columns option would non be accurate, because the lonesome delimiter disposable is a space. Because some of the states have quaternary names much arsenic Edward Antony Richard Louis Island, the Text to Columns function would circulate the information across too many a columns.
C. The solution is to role the =RIGHT function. Because some of the ZIP codes have five digits and some have half-dozen, enter the following command in cell E2: =RIGHT(D2,6), then replicate from E2 down to E3 finished E16. Done. Column E now contains ZIP codes only. Still, editorial D quiet has both states and ZIP codes.
15 & 16. LEFT & LEN
Use this subroutine to separate the states from the ZIP codes. Enrol the following formula in cell F2: =LEFT(D2,LEN(D2)-6), then copy down from F2 to F3 done F16. Basically this formula says go to cell D2, count 6 places from the left and remove those characters, leaving the left over characters in cell D2 (unheeding of how many). As long as indefinite piece of information inside a cell is unique, you can use that information to add, erase, operating theater replace other information privileged that cell.
To move or wangle the data in columns E or F (which contain formulas), highlight the column and choose Imitate, move pointer to another column, and opt Paste Special> Values, then chatter OK.
JD Sartain/IDG Using the RIGHT, LEFT, and LEN functions
17. PMT
Use this accessible part to determine how much your payments would equal thereon new cable car you just took for a trial run campaign. The process is simple: Enter the subprogram followed by the rate of interest divided by 12 (for 12 months), the Term (or number of monthly payments), followed away the Loanword Amount.
Enter this formula in cell F2: =PMT(D2/12,E2,C2,0,0), then copy from F2 down to F3 through F6.
To count a down payment, enter the down payment percentage in column F; enter the formula in column G; introduce the adjusted loanword number normal in column H; and the new monthly defrayal formula in column I. Likewise, convert the Term (in months) to Term (in years) in column E—for example, instead of 360 months for the House Loanword, enter 30 years.
Enter the following formula in cell G10: =SUM(C10*F10). Enter this formula in cellular phone H10: =SUM(C10-G10). And enter this formula in cell I10: =PMT(D10/12,E10*12,H10,0,0). Note that the Interest Rate is still divided by 12, and also, that the Term (in years) is multiplied by 12.
JD Sartain/IDG Use the PMT function to calculate your auto payments for that new car
Handy tip: Ever wonderment why some currency formats midway the dollar amount and the dollar bill sign ($1500.00), while others push the Numbers allied to the right and push the dollar mark aligned to the left ($ 1500.00)? To center the number and dollar mark, highlight the cell, and choose Home tab > List group > Number Initialise > Currency. To align the dollar sign on left and the numbers pool right, highlight the cell, then click the $ symbol in the Number group.
