ISERR function in Google Sheets

Checks whether a value is an error other than `#N/A`.

=ISERR(value)

ISERR syntax and parameters

One argument, one required.

  • valueanyRequired

    The value to be verified as an error type other than #N/A. ISERR returns TRUE if value is any error other than #N/A,including #DIV/0!, #NAME?, #NULL!, #NUM!, #VALUE!, and #REF!. This is useful in certain applications where #N/A may be a valid outcome, whereas the other error types always indicate a fundamental problem.

ISERR examples

Formulas you'll actually reuse.

  1. Trap #DIV/0! and #VALUE! but let #N/A through — ISERR ignores #N/A:

    =IF(ISERR(C2 / B2), "Check inputs", C2 / B2)

    Result"Check inputs"

  2. Count calculation errors in a column, not counting missing lookups:

    =SUMPRODUCT(--ISERR(F2:F200))

    Result3
