IFERROR Formula Syntax
Example Use Case
Handling errors in formulas by providing an alternative result
Understanding the IFERROR Formula
The IFERROR function in Excel evaluates an expression and returns an alternative value if it results in an error, otherwise returns the expression's result. It's an error-handling tool for graceful fallbacks—like preventing #DIV/0! or #N/A from disrupting your worksheet.
IFERROR(A1/B1, "Division Error") returns the division result if successful, or "Division Error" if B1 is zero or empty. It takes a value and value_if_error, streamlining error handling without nested IF functions.
Why Use IFERROR?
IFERROR creates resilience—think cleaner reports or user-friendly outputs. Its simplified syntax catches any error type, making your formulas more robust and presentable with minimal effort.
Example with Sample Data
| Expression, Fallback | Formula | Result |
|---|---|---|
| 10/2, "Error" | =IFERROR(10/2, "Error") | 5 |
| 10/0, "Error" | =IFERROR(10/0, "Error") | Error |
| VLOOKUP("x", A1:B5, 2), "Not Found" | =IFERROR(VLOOKUP("x", A1:B5, 2), "Not Found") | Not Found |
IFERROR smooths errors: normal results pass through, errors become friendly messages. It's an error catcher.
