Total rows that match status, date, category, customer, or region rules.
Count rows across multiple text, number, and date conditions.
Use case
Build dynamic array filters that return matching rows from a table instead of only counting or summing them.
Use this page when you need a live subset of rows from a larger table, such as open deals by region, late tasks by owner, or orders above a threshold. FILTER is a better fit than COUNTIFS or SUMIFS when the matching row details should remain visible.
Do not use FILTER as a drop-in replacement for the spreadsheet filter menu if the result should not spill into nearby cells. The formula returns an array, so blocked output cells can stop it from displaying correctly.
For deals in A2:D500, a FILTER formula can return only West-region deals that are still open and above 5000.
=FILTER(A2:D500,(B2:B500="West")*(C2:C500="Open")*(D2:D500>5000),"No matching rows")
The formula returns matching rows from A through D, keeps only rows where the region, status, and value tests are all true, and shows a fallback when no rows match.
