The Formula

Prompt

"Compare a VLOOKUP and XLOOKUP doing the same lookup"

Excel 
=XLOOKUP(D2,A2:A100,B2:B100,"Not found")

XLOOKUP replaces VLOOKUP with cleaner syntax, built-in error handling, and the ability to search in any direction. The VLOOKUP equivalent would be =VLOOKUP(D2,A2:B100,2,FALSE) but lacks the not-found fallback.

Step-by-Step Breakdown

  1. VLOOKUP requires a column index number (2) — fragile if columns change
  2. XLOOKUP references the return range directly (B2:B100) — column-safe
  3. XLOOKUP has a built-in "Not found" parameter — no IFERROR needed
  4. VLOOKUP can only search left-to-right; XLOOKUP searches any direction
  5. XLOOKUP defaults to exact match; VLOOKUP defaults to approximate (a common bug source)

Edge Cases & Warnings

  • VLOOKUP's approximate match default (TRUE) causes silent wrong results — always use FALSE
  • XLOOKUP requires Excel 365/2021; VLOOKUP works everywhere
  • Both are case-insensitive by default
  • For backward compatibility with older Excel versions, VLOOKUP is safer

Examples

Prompt

"VLOOKUP: =VLOOKUP(D2,A2:B100,2,FALSE)"

Excel 
Returns match or #N/A
Prompt

"XLOOKUP: =XLOOKUP(D2,A2:A100,B2:B100,"Not found")"

Excel 
Returns match or "Not found"

Frequently Asked Questions

Should I stop using VLOOKUP?

If you have Excel 365 or 2021, yes — XLOOKUP is better in every way. If you share files with people on older versions, keep VLOOKUP for compatibility.

Is XLOOKUP faster than VLOOKUP?

In most cases, yes. XLOOKUP can search from last to first (useful for recent entries) and doesn't scan unnecessary columns.
