How-to Guide

1. Use the ISERR function

Entry point: Formulas tab → formula bar

  1. Open AirSheet and select the cell where you want to show the result.
  2. Type = in the formula bar or directly in the cell.
  3. Type ISERR( and review the syntax prompt.
  4. Enter the value, cell reference, or formula expression that you want to test.
  5. Type the closing parenthesis ) and press Enter.
  6. Review the result: if the target is an error other than #N/A, the function returns TRUE; otherwise, it returns FALSE.

Success Criteria

  • UI state: The target cell shows TRUE or FALSE.
  • Next actions: You can continue to nest ISERR inside formulas such as IF.
  • No side effects: The original data cell is not directly changed.

Tips While Using

  • Start the formula with =.
  • Make sure the parentheses are paired correctly and the expression is complete.
  • ISERR does not treat #N/A as TRUE. If you need to check all errors, use a different error-checking formula.
  • If the referenced cell or formula is incomplete, the result may not match your expectation.
