Generated FormulaExcel 365 / Google Sheets

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

How this formula works

lookup_value:Value you want to search for in the dataset.

lookup_array:Array where Excel will locate the lookup value.

return_array:Values to return once a match is found.

[if_not_found]:Graceful fallback instead of displaying ugly #N/A errors.

Common Pitfall & Error Prevention

Ensure lookup_array and return_array have identical dimensions (same number of rows/columns) to avoid #VALUE! errors.
