ISERR function in Excel

Returns TRUE if the value is any error value except #N/A

=ISERR(value)

ISERR syntax and parameters

One argument, one required.

  • valueanyRequired

    The value that you want tested. The value argument can be a blank (empty cell), error, logical value, text, number, or reference value, or a name referring to any of these.

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
