Struggling with #DIV/0! or #N/A errors in your Excel sheets? The IFERROR function helps you tidy your data. It gives backup results and boosts spreadsheet accuracy. This guide explains the IFERROR function. We’ll show you how to use it in Excel and answer common questions. This way, you can make your formulas error-proof.
What is the IFERROR Function in Excel?
The IFERROR function in Excel helps you find and manage errors in your formulas. IFERROR lets you replace Excel error messages like #DIV/0!, #N/A, or #VALUE! with your own custom value or message.
Syntax:
=IFERROR(value, value_if_error)
- value: The formula or expression you want to evaluate.
- value_if_error: The result you want Excel to return if an error occurs.
Example:
=IFERROR(A2/B2, “Invalid”)
This divides A2 by B2. If B2 is zero (causing a #DIV/0! error), it will show “Invalid” instead of an error message.
How to Use Excel IFERROR Function (Step-by-Step Guide)
Let’s walk through how to use IFERROR in different practical scenarios:
Handle Division Errors
=IFERROR(A2/B2, “Error: Division by 0”)
Great for financial or statistical sheets where division happens often, but can break with zero values.
Clean Up VLOOKUP or XLOOKUP Errors
=IFERROR(VLOOKUP(E2, A2:B10, 2, FALSE), “Not Found”)
Instead of #N/A, this shows a user-friendly “Not Found” message when a match isn’t located.
Substitute Blanks Instead of Errors
=IFERROR(F2*G2, “”)
Great for dashboards or reports where empty cells look cleaner than error messages.
Combine with Text for Clear Messaging
=IFERROR(“Result: ” & A1/B1, “Result: Not Available”)
Creates readable, human-friendly outputs in reports or summaries.
Best Practices
- Pair IFERROR with functions like VLOOKUP, MATCH, or custom formulas to create cleaner user experiences.
- Avoid hiding serious data issues. IFERROR should be used for handling expected errors, not masking problems.
- Log or highlight recurring errors in a separate cell using conditional formatting or comments for better data auditing.
- For better traceability, consider combining with IF or ISERROR if you need more granular control.
