IFERROR function

Returns a value you specify if a formula evaluates to an error; otherwise, returns the result of the formula

Syntax

IFERROR(value, value_if_error)

Square brackets indicate optional arguments.

Arguments

ArgumentRequiredMeaning
valueYesThe argument that is checked for an error.A2/B2
value_if_errorYesThe value to return if the formula evaluates to an error. The following error types are evaluated: #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!."Error in calculation"

Try IFERROR

Keep an error-looking text label while replacing a real error

=HSTACK(IFERROR(A2,"Missing"),IFERROR(B2,"Missing"))

A2 contains the text label #N/A; B2 calculates NA(), a real error. IFERROR keeps the text label and replaces only the error with Missing. The two values can look alike in a grid but have different types. This two-column display uses HSTACK; older Excel versions can place the two IFERROR calls in separate cells.
