The IFERROR function in Excel allows you to catch and handle formula errors gracefully by returning a custom value instead of error messages like #DIV/0!, #N/A, or #VALUE!. 🧹 For example, =IFERROR(A1/B1, "Error") will return “Error” if the formula fails. This makes your spreadsheets cleaner, more professional, and easier to read—especially when shared with others or used in dashboards. 📊
🔍 What Is the IFERROR Function?
The IFERROR function checks if a formula returns an error. If it does, it shows a custom value instead. If no error is found, the original result is shown.
Syntax:
=IFERROR(value, value_if_error)
value: The formula or expression to evaluatevalue_if_error: What to show if an error occurs
Example:
=IFERROR(A2/B2, "Divide by zero error")
If B2 is zero, Excel won’t show #DIV/0!—you’ll see “Divide by zero error” instead. 💡
💻 Keyboard Shortcuts for Writing IFERROR in Excel
While there’s no shortcut just for IFERROR, you can speed up writing and editing formulas with these:
| Action | Windows | macOS | Ubuntu (LibreOffice Calc) |
|---|---|---|---|
| Start formula | = | = | = |
| Insert function | Shift + F3 | Shift + F3 | Ctrl + F2 |
| Enter/accept formula | Enter | Return | Enter |
| Toggle formula bar | Ctrl + Shift + U | Cmd + Shift + U | Ctrl + Shift + U |
Use Shift + F3 to open the Insert Function dialog and type “IFERROR” for quick access.
🧠 Why Use IFERROR?
- Avoid ugly errors like
#DIV/0!,#N/A,#VALUE!, etc. 😖 - Make your sheets cleaner and more user-friendly 🧼
- Provide meaningful fallback messages like “Not Available” or “Check Input”
- Maintain smooth dashboard visuals without error interruptions
- Perfect for VLOOKUP, INDEX/MATCH, and math operations
🧩 Common IFERROR Examples
| Scenario | Formula | Result |
|---|---|---|
| Division by zero | =IFERROR(A1/B1, "Invalid") | “Invalid” if B1=0 |
| VLOOKUP fallback | =IFERROR(VLOOKUP(A2, D2:E10, 2, FALSE), "Not found") | Replaces #N/A |
| Missing data | =IFERROR(B2*C2, 0) | Returns 0 if cells are blank or invalid |
| Error handling with text | =IFERROR("Price: "&A2/B2, "Check Input") | Combines text and error check |
🔀 IFERROR vs IF + ISERROR
Old-school method:
=IF(ISERROR(A2/B2), "Error", A2/B2)
Modern (better) method:
=IFERROR(A2/B2, "Error")
✅ Use IFERROR — it’s cleaner, shorter, and easier to read!
🧪 Use with Nested Formulas
=IFERROR(IF(A2>100, A2/2, A2*2), "Invalid input")
This will return “Invalid input” if there’s any error in the logic, instead of breaking your spreadsheet with error codes.
🎯 Best Use Cases for IFERROR
| Use Case | Recommended? |
|---|---|
| Financial reports | ✅ Absolutely |
| Dashboards | ✅ To suppress ugly errors |
| Lookup functions | ✅ Replace #N/A with custom messages |
| Division operations | ✅ Prevent #DIV/0! |
| Data cleaning | ✅ Fill blanks with default values |
🐧 IFERROR in Ubuntu (LibreOffice Calc)
LibreOffice Calc supports IFERROR too:
=IFERROR(A1/B1, "Invalid")
- Open Function Wizard:
Ctrl + F2 - Navigate to Logical > IFERROR
💡 For older versions without IFERROR, use:
=IF(ISERROR(A1/B1), "Error", A1/B1)
⚠️ Common Mistakes to Avoid
- ❌ Using IFERROR to hide problems you should fix
- ❌ Forgetting that IFERROR hides all errors—including typos and wrong ranges
- ❌ Not testing the fallback value (e.g., showing “0” when it should be “N/A”)
- ❌ Overusing IFERROR to mask broken logic
✅ Tip: Use IFERROR responsibly—only when you expect errors that can be ignored or handled gracefully.
