Use case

XLOOKUP formula generator for spreadsheet work.

Create a modern exact-match lookup with separate lookup and return ranges.

What this page gives you

  • A draft XLOOKUP with separate lookup and return ranges.
  • A readable fallback for missing matches.
  • Checks that the lookup range and return range line up.

When to use it

Use this page when the workbook supports XLOOKUP and you want a lookup that is easier to read than VLOOKUP, especially when returning values from either side of the key.

Do not choose XLOOKUP for workbooks that must open cleanly in older Excel versions. Use VLOOKUP or INDEX/MATCH when compatibility is the main constraint.

Worked example

For a customer ID in E2, XLOOKUP can search IDs in column A and return emails from column C.

=XLOOKUP(E2,$A$2:$A$500,$C$2:$C$500,"Not found")

The formula searches the ID list, returns the matching email, and uses Not found instead of a raw lookup error.

Check before you paste

  • Confirm the lookup range and return range have the same height.
  • Keep the not-found fallback meaningful for downstream reports.
  • Use modern Excel or Google Sheets before choosing XLOOKUP.
