I am trying to make an arrayformula in column B, which will copy whatever is in column A into C
| A | B | C |
|---|---|---|
| aaa | some (array)formula | aaa (the contents of A1) |
| bbb | bbb (the contents of A2) | |
| ccc | bbb (the contents of A3) |
at the moment I can use this formula on individual cells in column B: ={"",A1}
However when I try to put this into an arrayformula: =arrayformula({"",A1:A10}) it just returns an error:
Function ARRAY_ROW parameter 2 has mismatched row size. Expected: 1. Actual: 9.
Is there any way to do this?
