Function name:
ISERROR
Category:
Information
Summary:
Determines if a specified cell or expression evaluates to an error type.
In contrast to Calc’s ISERR function, ISERROR returns TRUE if the argument evaluates to the value not available error (#N/A).
Syntax:
ISERROR(Value)
Returns:
Returns TRUE if the argument evaluates to an error and returns FALSE otherwise.
Arguments:
Value is an expression, or a reference to a cell containing an expression, that is to be tested for an error condition.
Additional details:
- ISERROR does not propagate errors. If Value evaluates to an error then ISERROR returns TRUE and returns FALSE otherwise.
- Use the ISERR function to test for errors if you do not wish to include #N/A as an error condition.
- Use ISERROR in conjunction with the IF function to test for errors and take different actions in normal and error conditions.
Examples:
| Formula | Description | Returns |
|---|---|---|
| =ISERROR(12.34) | Here the function returns the logical value FALSE. | FALSE |
| =ISERROR("Hello world!") | Here the function returns the logical value FALSE. | FALSE |
| =ISERROR(TRUE()) | Here the function returns the logical value FALSE. | FALSE |
| =ISERROR(2021-12-18) | Here the function returns the logical value FALSE. | FALSE |
=ISERROR(D1) where cell D1 contains the formula =1/0. |
Here cell D1 contains a #DIV/0! error and so the function returns the logical value TRUE. | TRUE |
=ISERROR(D2) where cell D2 contains the formula =SQRT(-7). |
Here cell D2 contains an invalid argument error (Err:502) and so the function returns the logical value TRUE. | TRUE |
=ISERROR(D3) where cell D3 contains the formula =NA(). |
Here cell D3 contains a #N/A error and so the function returns the logical value TRUE. | TRUE |
