If you’ve used Excel for more than a week, you’ve probably seen at least one scary-looking error message.

#VALUE!
#DIV/0!
#N/A

They look technical. Sometimes confusing. But the truth is that most Excel errors are simple to fix once you understand what they mean.

In this guide, we’ll break down 13 common Excel errors and how to fix them quickly, so you can work smarter and faster.

1. #DIV/0!

What it means: You’re dividing by zero or an empty cell.

Fix:
Wrap your formula with IFERROR:

=IFERROR(A1/B1, 0)

Or check that the denominator is not zero before dividing.

2. #VALUE!

What it means: The formula is using the wrong data type (e.g., text instead of numbers).

Fix:

• Check for hidden spaces
• Convert text to numbers using VALUE()
• Ensure your formula references correct cell types

3. #REF!

What it means: A cell reference is invalid (usually after deleting a column or row).

Fix:
Restore the deleted column or update the formula to the correct reference.

4. #NAME?

What it means: Excel doesn’t recognize text in your formula.

Common causes:

• Misspelled function (e.g., SUMM instead of SUM)
• Missing quotation marks around text

Fix:
Check spelling and ensure text values are in quotes.

5. #N/A

What it means: A lookup function couldn’t find a match.

This is common with VLOOKUP or XLOOKUP.

Fix:

• Check for extra spaces
• Ensure exact match settings are correct
• Use IFERROR to handle missing values

6. #NUM!

What it means: Invalid numeric value.

Example:

• Square root of a negative number
• Extremely large calculations

Fix:
Check your numeric input values.

7. #NULL!

What it means: Incorrect use of a space in a formula where a comma is required.

Fix:
Replace space with a comma or correct operator.

8. Circular Reference Warning

What it means: A formula refers to its own cell directly or indirectly.

Fix:
Go to Formulas → Error Checking → Circular References and adjust your formula.

9. ####### (Hash Symbols)

What it means: Column width is too small.

Fix:
Double-click the column border to auto-fit.

Simple. But very common.

10. Spill Error (#SPILL!)

Common in modern Excel versions.

What it means: A dynamic array formula can’t expand because something is blocking the range.

Fix:
Clear the cells blocking the spill range.

11. Formula Not Calculating

What it means: Excel is set to Manual calculation mode.

Fix:
Go to Formulas → Calculation Options → Automatic.

12. Text Appearing Instead of Formula Result

If your formula shows like this:

=SUM(A1:A10)

Instead of a number.

Fix:

• Remove leading apostrophe
• Change format from Text to General
• Press F2 then Enter

13. #CALC!

Common in newer Excel versions.

What it means: A calculation error in dynamic arrays.

Fix:
Check your formula logic and ensure array inputs are valid.

Why Understanding Excel Errors Matters

If you’re working in tools like Microsoft Excel or integrating Excel data into Microsoft Power BI, small formula errors can break dashboards and reports.

Knowing how to fix errors quickly:
