IfError

 

Use the IFERROR function in Excel to return an alternative result, such as text, when a formula evaluates to an error.

Note: the IFERROR function catches the following errors: #DIV/0!, #N/A, #VALUE!, #REF!, #NUM!, #NAME? and #NULL!. For example, the IFERROR function shown above also catches the #NAME? error if you accidentally misspell the word VLOOKUP. Use the IFNA function in Excel 2013 or later to only catch #N/A errors.
