104 Part II: Using Functions in Your <strong>Formula</strong>s Simplify your formulas Using a built-in function can simplify a formula significantly. For example, you might need to calculate the average of the values in 10 cells (A1:A10). Without the help of any functions, you would need to construct a formula like this: =(A1+A2+A3+A4+A5+A6+A7+A8+A9+A10)/10 Not very pretty, is it? Even worse, you would need to edit this formula if you inserted a new row in the A1:A10 range and needed the new value to be included in the average. However, you can replace this formula with a much simpler one that uses the AVERAGE function: =AVERAGE(A1:A10) Perform otherwise impossible calculations Functions permit formulas to perform calculations that go beyond the standard mathematical operations. Perhaps you need to determine the largest value in a range. A formula can’t tell you the answer without using a function. This formula uses the MAX function to return the largest value in the range A1:D100: =MAX(A1:D100) Speed up editing tasks Functions can sometimes eliminate manual editing. Assume that you have a worksheet that contains 1,000 names in cells A1:A1000 and that all the names appear in all-uppercase letters. Your boss sees the listing and informs you that you need to mail-merge the names with a form letter and that the use of all uppercase is not acceptable. For example, JOHN F. CRANE must appear as John F. Crane. You could spend the rest of the afternoon reentering the list — or you could use a formula such as the following, which uses the PROPER function to convert the text in cell A1 to proper case: =PROPER(A1) 1. Type this formula in cell B1 and then copy it down to the next 999 rows. 2. Select B1:B1000 and choose Home➜Clipboard➜Copy to copy the range to the Clipboard (or press Ctrl+C).
Chapter 4: Introducing Worksheet Functions 105 3. Activate cell A1 and choose Home➜Clipboard➜Paste➜Paste Values to convert the formulas to values. 4. Delete column B. You’re finished! With the help of a function, you just eliminated several hours of tedious work in less than a minute. Provide decision-making capability You can use the Excel IF function to give your formulas decision-making capabilities. Suppose that you have a worksheet that calculates sales commissions. If a salesperson sells at least $100,000 of product, the commission rate reaches 7.5 percent; otherwise, the commission rate remains at 5.0 percent. Without using a function, you would need to create two different formulas and make sure that you use the correct formula for each sales amount. This formula uses the IF function to check the value in cell A1 and make the appropriate commission calculation: =IF(A1
