How-to Guide
1. Enter the IFERROR function
Entry point: Formulas tab → formula bar
- Open a spreadsheet and select the cell where you want to enter the formula.
- Type
=in the cell or formula bar. - Continue by typing
IFERROR(. - Review the syntax prompt and confirm the function name and argument order.
Success Criteria
- Interface result: The cell enters formula editing mode and shows
IFERROR(. - What you can do next: You can continue entering arguments and complete the formula.
Tips While Using
- Common mistake: If you do not start with
=, the content may be treated as plain text.- Environment note: Use an editable spreadsheet cell.
2. Fill in the arguments by syntax
Entry point: Selected target cell → formula bar
- After
IFERROR(, enter the formula or expression you want to test. - Enter the argument separator used in your spreadsheet settings.
- Enter the text, number, or other result to return when an error occurs.
- Type the closing parenthesis and press Enter.
Success Criteria
- Interface result: The cell shows either the calculation result or the fallback value you set.
- What you can do next: You can fill down or copy the formula to other cells.
Tips While Using
- Common mistake: Missing parentheses, incorrect argument order, or a missing separator can prevent the formula from calculating correctly.
3. Use IFERROR in nested or reference formulas
Entry point: Formula bar
- Prepare the original formula, such as a lookup, division, or cross-sheet reference formula.
- Place that original formula in the first argument of
IFERROR(. - Set the second argument to the result you want returned on error, such as
0, a blank text string, or a message. - Press Enter and review the result.
Success Criteria
- Interface result: When the original formula works, the original result appears; when it errors, the fallback result appears.
- What you can do next: You can continue adjusting ranges, sheet references, or the fallback value.
Tips While Using
- Common mistake: If the original formula has a reference issue, also check the referenced cells or sheet names.
4. Check results and let them update with data changes
Entry point: Cell range that already contains the formula
- Change the source data used by the formula.
- Watch the result in the cell that contains IFERROR.
- Confirm that valid data shows the calculated result and invalid data shows the fallback result.
- If the result is not what you expect, return to the formula bar and adjust the arguments.
Success Criteria
- Interface result: The result updates when the data changes.
- What you can do next: You can copy the formula, adjust the fallback value, or extend it to more cells.
Tips While Using
- Common mistake: If referenced cells use an incompatible data format, the fallback result may continue to appear.
