Google Sheets Query - Remove Blank Column Header

Question

I'm running a simple Google Sheets Query like:

=query({input1!A2:D},"select Col1,' ','  ','   ',Col2,Col3 where Col1 is not null",0)

I'm leaving blank columns which works great, but instead, I have a header like below appearing:

" "()   "  "()  "   "()

How can I remove them?

Answer 1

you can remove it by adding empty label ' ''',' ''',' '''

=QUERY({input1!A2:D}, "select Col1,' ','  ','   ',Col2,Col3 
                       where Col1 is not null
                       label ' ''','  ''','   '''", 0)
