ISERROR function in Excel

Returns TRUE if the value is any error value

=ISERROR(value)

ISERROR 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.

ISERROR examples

Formulas you'll actually reuse.

  1. A lookup that says so instead of showing #N/A:

    =IF(ISERROR(VLOOKUP(A2, Prices!A:B, 2, FALSE)), "No price", VLOOKUP(A2, Prices!A:B, 2, FALSE))

    Result"No price"

  2. How many rows of a column are errors of any kind:

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

    Result5
