TROUBLESHOOTING

Common VLOOKUP Errors & How to Fix Them

Even experienced users run into these. Learn what causes each error and how to solve it in seconds.

#N/A

Value Not Found

Most common VLOOKUP error

Why it happens:

  • • The lookup value doesn't exist in the first column
  • • Extra spaces or hidden characters in the data
  • • Data type mismatch (text "100" vs number 100)

How to fix:

  • ✓ Use TRIM() to remove extra spaces
  • ✓ Wrap with IFERROR(VLOOKUP(...), "Not found")
  • ✓ Ensure both values are the same data type
#REF!

Invalid Column Index

Column number exceeds range

Why it happens:

  • col_index_num is larger than the number of columns in your range
  • • Example: requesting column 5 from a 4-column range

How to fix:

  • ✓ Count your columns carefully — Column A of the range = 1
  • ✓ Expand the table_array to include more columns
  • ✓ Use COLUMNS(A1:D1) to verify your range width
#VALUE!

Invalid Argument

Wrong parameter type

Why it happens:

  • col_index_num is less than 1
  • lookup_value exceeds 255 characters
  • • Formula entered as an array formula incorrectly

How to fix:

  • ✓ Ensure col_index_num ≥ 1
  • ✓ Shorten lookup values or use a helper column
  • ✓ Check for invisible special characters with LEN()

Wrong Result Returned

No error shown, but data is incorrect

Why it happens:

  • • Using TRUE (approximate match) instead of FALSE
  • • Table range not locked with $ signs (shifts when copied)
  • • Duplicate values in the lookup column

How to fix:

  • ✓ Always use FALSE for exact match (99% of cases)
  • ✓ Lock your range: $A$1:$D$6
  • ✓ Remove duplicate lookup values or use INDEX/MATCH

Pro Tip: Always Wrap with IFERROR

Use =IFERROR(VLOOKUP(...), "Not found") to gracefully handle errors and keep your spreadsheet clean. WPS AI can add this automatically when generating formulas.
