ARRAYFORMULA in Google Sheets enables the display of values returned from an array formula into multiple rows and/or columns, and also allows you to use non-array functions with arrays.
This means that you can apply a formula to a range of cells, and have the results displayed in multiple rows or columns, depending on the size of the array.
Additionally, you can use non-array functions such as COUNTIF and IFERROR with an array formula.
