Can I compare two columns without VLOOKUP or COUNTIF?

Yes. If each row is one ID, email, or name, paste each column into ListDiff and use the result tabs—no spreadsheet formulas needed.

When should I still use VLOOKUP in Excel?

Keep formulas when you must stay inside one workbook, need live updates as cells change, or match across many columns with complex conditions—not a single key list.
