Advanced Excel Error Handling Techniques
1. IFERROR Function
=IFERROR(VLOOKUP(A2,B:C,2,FALSE),"Not Found")
2. ISERROR Function
Checks whether a value is an error.
3. Data Validation
Prevents wrong data entry.
4. Conditional Formatting
Highlights errors automatically.
Real-Life Example
Imagine you are preparing a sales report:
- Missing customer data → #N/A
- Division by zero in profit → #DIV/0!
- Deleted column → #REF!
Without proper error handling, your report becomes unreliable.
Best Practices to Avoid Excel Errors
- Always validate data
- Use IFERROR in formulas
- Avoid hardcoding values
- Use named ranges
- Keep formulas simple
- Test before final submission
