Google sheets arrayformula of arrays

Question

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?

Answer 1

Another solution:

=index(iferror(if({0/0,1},A:A)))

Or:

=query(A:A,"select 0/0, A label 0/0 ''")

Answer 2

Another one:

=ArrayFormula({if(A:A="",,),A:A})

Answer 3

Try

=arrayformula(if(A1:A="",,A1:A))

Answer 4

This is one way to do it. Note that you need to have FALSE or 0 for the 4th split parameter (as illustrated) for this to work.

=ARRAYFORMULA(SPLIT("|"&A1:A10,"|",0,0))
