IFERROR Formula Excel

This Excel Tutorial demonstrates how to use the Excel IFERROR Function in Excel to test for an error and if one is found do something else, with formula examples.

IFERROR Function Description:

The IFERROR Function Checks if a formula results in an error. If FALSE, return the original result of the formula. If TRUE, return another specified value.

Formula Examples:

Example Formula Result
No Error =IFERROR(C5,D5) 1
Error =IFERROR(C6,D6) “error”
Error – Display Blank =IFERROR(C7,””)
Error – Do 2nd Calc =IFERROR(5/C8,5/D8)

Syntax and Arguments:

The Syntax for the IFERROR Formula is:

Function Arguments ( Inputs ):

value – An expression. Example: 4/A1

value_if_error – Value or Calculation to perform if the previous input results in an error. Example 0 or “” (blank)

Additional Notes

Use the IFERROR Function to test if a calculation results in an error. If it does, then do something else, if not then keep the original result.

Often the IFERROR Function is used with lookup functions, such as VLOOKUPs. If the lookup_value is not found, typically an error is returned, but by adding IFERROR to the formula, the formula can return blank (“”), “not found”, or do something else. Use formulas such as these to make your spreadsheets appear cleaner.
