I tried to use Query function and it was functioning well at first. I initially only had 7 columns. However, when I tried to use to my document with up Column AZ, it is not working anymore.
This was the formula I used:
=QUERY({'Trial Data 1'!A2:H;'Trial Data 2'!A2:H;'Trial Data 3'!A2:H},"select * where Col1 is not null",0)
This was the formula for my other doc with up to column AZ that resulted to Parse Error:
=QUERY({'Trial Data 1'!A2:AZ;'Trial Data 2'!A2:AZ;'Trial Data 3'!A2:AZ},"select * where Col1 is not null",0)
Also, is there a way that only the data of selected columns will show? For example, only columns A, B, G, H, J, K, etc. will show?
Thank you.
