1) #N/A Error — Value Not Available

The #N/A error appears when Excel cannot find the value you’re looking for. This is most common in lookup functions like VLOOKUP, XLOOKUP, or INDEX-MATCH.

=VLOOKUP("ABC", A2:B100, 2, FALSE)

Fix: Double-check the lookup value, spelling, and data source. Use IFERROR or IFNA to display a cleaner message like “Not Found.”

2) #DIV/0! Error — Division by Zero

This happens when you try to divide a number by zero or by an empty cell.

=A2/B2

Fix: Ensure the denominator is not zero or blank. Wrap the formula with IFERROR or IF(B2=0,"",A2/B2) to avoid breaking calculations.

3) #REF! Error — Invalid Reference

The #REF! error occurs when a formula refers to a cell that has been deleted or moved.

=A1+B1

Fix: Avoid deleting referenced cells. Recheck formulas after shifting or removing rows/columns.

4) #VALUE! Error — Wrong Data Type

This error means Excel is trying to perform a calculation with incompatible data, like adding text to a number.

="Text"+10

Fix: Confirm that all inputs are numbers. Use functions like VALUE() to convert text numbers into proper numeric values.

5) #NAME? Error — Unrecognized Function

Excel shows #NAME? if you mistype a function name or reference a named range that doesn’t exist.

=SUMM(A1:A10)

Fix: Check spelling of function names and ensure named ranges are defined correctly.

6) #NULL! Error — Incorrect Range Operator

This appears when you mistakenly use a space instead of a comma or colon in a formula.

=SUM(A1 A10)

Fix: Replace the space with a proper operator. Example: =SUM(A1:A10).

Quick Reference Table

Error Meaning Fix
#N/A Value not found Check lookup values or use IFNA
#DIV/0! Division by zero Ensure denominator isn’t zero
#REF! Invalid cell reference Avoid deleting referenced cells
