expression - A variable that represents a ApiWorksheetFunction class.

Parameters​

NameRequired/OptionalData typeDefaultDescription
arg1RequiredApiRange | ApiName | number | string | booleanThe value, expression, or reference that is checked for an error.
arg2RequiredApiRange | ApiName | number | string | booleanThe value to return if the formula evaluates to the <em>#N/A</em> error value.

Returns​

number | string | boolean

Example​

This example shows how to check if there is an error in the formula in the first argument. The function returns the specified value if the formula returns the N/A error value, otherwise returns the result of the formula.

// How to check whether a formula result is N/A.

// Use a function to get a result from a formula if an error occurs show specified error message.
