So I would like to create a function or something that returns absolutely nothing in a cell.
When I say nothing, I mean that if the cell before returns an array of value, it can write in this cell and doesn't returns #REF (Cannot expand results).
The idea is that I have a function sort() that get me a list of keys. Then I retrieve the values with a filter function like so :
=FILTER(B$2:B$7, A$2:A$7=D2)
But sometimes the keys (which are dates) can be duplicated, and that makes that the FILTER function with return 2 times 2 rows, creating a #REF error (cannot expand results).
If I create a condition :
=IF(D1<>D2, FILTER(/*...*/), "")
The second cell is empty but I still get the #REF error, because it's not really empty.
Is there a way to make that work ?
