MAP

Returns an array formed by mapping each value in the array(s) to a new value by applying a LAMBDA to create a new value.

Syntax The MAP function syntax has the following arguments and parameters: array1 An array to be mapped. lambdaorarray<#> A LAMBDA which must be the last argument and which must have either a parameter for each array passed, or another array to be mapped. Tip Before using this function, you need to turn on the allowDynamicArray option Basic Usage Square numbers above a certain value Find values from two columns in one row that are both TRUE
