IFERROR(value, value_if_error) The IFERROR function syntax has the following arguments: Value Required. The argument that is checked for an error. Value_if_error Required. The value to return if the formula evaluates to an error.
In earlier versions of Excel, we have a formula called as ISERROR() that can check an expression or formula for error and return TRUE if so. This formula is not same as IFERROR, but we can use it along with IF() formula to get the same result.
