Checks if a value is any error type except #N/A.
Deze functie werkt in Google Spreadsheets hetzelfde als in Excel — dezelfde syntaxis en argumenten.
ISERR(value)The ISERR function returns TRUE if the provided value is an error such as #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!. Unlike the ISERROR function, ISERR specifically excludes the #N/A error from its TRUE result.
=ISERR(1/0)Resultaat: TRUE
Returns TRUE because 1/0 results in the #DIV/0! error.
=ISERR(NA())Resultaat: FALSE
Returns FALSE because ISERR ignores the #N/A error.
ISERR returns FALSE for #N/A errors, while ISERROR returns TRUE for all error types including #N/A.
