Note

The Excel IF Statement tests a given condition and returns one value for a TRUE result and another value for a FALSE result. For example, if sales total more than $5,000, then return a “Yes” for Bonus – Otherwise, return a “No” for Bonus. We can also use the IF function to evaluate a single function. Excel for Office 365 for Mac Excel 2019 for Mac Excel 2016 for Mac Excel for Mac 2011 If your formulas have errors that you anticipate and don't need to correct, you can improve the display of your results by hiding error values and error indicators in cells. Formulas can return errors for many reasons.

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Summary

In Microsoft Excel, when you use a formula that tests for a zero value, you may see unexpected results if the cell is blank. Microsoft Excel interprets a blank cell as zero, and not as empty or blank. Therefore, any cells that are blank are evaluated as zero in the function.

More information

If you are checking a cell for a zero value and the cell is blank, the test evaluates to true. For example, if you have the following formula in cell A1:

and B1 is blank, the formula returns 'zero' and not 'blank' as expected.

If the range might contain a blank cell, you should use the ISBLANK function to test for a zero value, as in the following example:

Note

The above formula returns 'zero' if there is a zero value in the cell, 'blank' if the cell is blank, and 'other' if anything else is in the cell.

You must always use the ISBLANK formula first before you test for a zero value. Otherwise you will always return a 'true' for the zero value, and never get to the test for the ISBLANK formula.
