How can I use the ISERROR function in Google Sheets?

Checks whether a value is an error.

Sample Usage

ISERROR(A2)

ISERROR(A1/A2)

IF(ISERROR(VLOOKUP(B1, A1:A100, 1, FALSE)), "Result not found", VLOOKUP(B1, A1:A100, 1, FALSE))

Syntax

ISERROR(value)

• value – The value to be verified as an error type.

  • ISERROR returns TRUE if value is any error, including #DIV/0!, #N/A, #NAME?,#NULL!, #NUM!, #VALUE!, and #REF!.

Notes

• ISERROR returns TRUE on any error, unlike ISERR, which returns TRUE on all errors except for #N/A. Ensure that the correct call is used.

• This function is most often used in conjunction with IF in conditional statements.
