Excel Formula Tips & Tricks
Use XLOOKUP Instead of VLOOKUP
XLOOKUP is the modern replacement — searches any direction, returns multiple columns, and handles errors natively.
=XLOOKUP(lookup, array, return, [not_found])Combine INDEX + MATCH
INDEX/MATCH is more flexible than VLOOKUP — can look up values in any column and is faster on large datasets.
=INDEX(return_range, MATCH(lookup, range, 0))Always Wrap with IFERROR
Prevent ugly #N/A errors by wrapping lookup formulas with IFERROR. Return a blank or custom message instead.
=IFERROR(VLOOKUP(A1, D:F, 2, 0), "Not Found")Use Dynamic Array Formulas
Excel 365 supports FILTER, SORT, UNIQUE — formulas that automatically spill results into multiple cells.
=FILTER(range, criteria, [if_empty])Ready to Extract Your Formulas?
