The FILTER function filters an array based on a boolean (true/false) array. For example:
Argument
Required
Description
array
Y
The array, or range to filter
include
Y
A Boolean array whose height or width is the same as the array
[if_empty]
N
The value to return if all values in the included array are empty (filter returns nothing)
Note:
The FILTER function is only valid when allowDynamicArray is true.
The FILTER function will retun an array, which will spill if it's the final result of a formula.
If your dataset has the potential of returning an empty value, then use the 3rd argument ([if_empty]). Otherwise, a #CALC! error will result.
If any value of the include argument is an error (#N/A, #VALUE, etc) or cannot be converted to a boolean, the FILTER function will return an error.
