How to create a conditional format to hide errors in Excel (182189)

MORE INFORMATION

In versions of Microsoft Excel earlier than Excel 97, you could not create a custom number format to hide error values returned to the cell by the cell formula. For example, if you enter the following in your worksheet:

   A1: =B1/C1   B1: 5   C1: 0
				

you would get #DIV/0! returned to cell A1. You can change the formula in cell A1 to hide the error value to the following: With the example values given above, this formula returns the empty string ("").

Note that there are other techniques for hiding error values that you can use in versions of Microsoft Excel earlier than Microsoft Excel 97.

Conditional Formatting allows you to use the simpler of the two formulas in cell A1 and still prevent the error value from appearing in cell A1.

The following example steps you through the use of Conditional Formatting to hide error values returned by formulas in cells:

1. Enter the following in a worksheet:

      A1: =B1/C1           B1: 5   C1: 0
      A2: =nofunction*B2   B2: 6   C2: 0
   						

   Note Cell A1 returns the #DIV/0! error value, and cell A2 returns the #NAME? error value because nofunction (used in cell A2) is not a valid function.
2. Select column A.
3. On the Format menu, click Conditional Formatting.
4. In the Conditional Formatting dialog box, click the Condition 1 drop-down, and then click Formula Is.
5. In the edit box to the right of the Condition 1 drop-down, enter the following formula:

   =ISERROR(A1)

6. Click the Format button. In the Format Cells dialog box, click the Color: drop-down, and then click the White square.
7. Click OK in the Format Cells dialog box, and then click OK in the Conditional Formatting dialog box.
   
   Note Because you selected column A in step 2, all the cells in column A were formatted with this Conditional Format. So, any other cells in column A that return error values will not display the error value.
