SUMPRODUCT is one of Excel’s most underestimated functions. Most users stop at multiplying two columns — but it can handle conditional sums, OR logic, weighted averages, date-based grouping, case-sensitive matches, and unique value counts, all without helper columns and in every Excel version from 2003 to 365. This guide shows you seven patterns that will change how you work with data.
VLOOKUP has been Excel’s most-used lookup function for decades — but XLOOKUP, available in Excel 365 and 2021, fixes every limitation VLOOKUP has.
