How to Use ARRAYFORMULA in Google Sheets
ARRAYFORMULA lets you apply a formula to an entire column or range with a single formula. This reduces spreadsheet size and improves performance.
Understand ARRAYFORMULA Syntax
ARRAYFORMULA(array_formula). Wrap any formula that works on a single cell with ARRAYFORMULA to make it work on an entire range.
Apply a Simple Array Formula
Use =ARRAYFORMULA(A1:A100*B1:B100) to multiply two entire columns without dragging the formula down.
Combine with IF Statements
Use =ARRAYFORMULA(IF(A1:A100="", "", A1:A100*B1:B100)) to skip blank rows and avoid errors.
Use with SUMIF or COUNTIF
Use =ARRAYFORMULA(SUMIF(A1:A100, "Criteria", B1:B100)) for array-enabled conditional calculations.
💡 ARRAYFORMULA is especially useful for dashboard calculations.
