Is it possible to refer to an entire column by its number in an Excel formula?

Question

Currently I am trying to set up a dynamic range using this formula structure:

=OFFSET($A$2,,,COUNTA($A:$A)-1)

I then modified the formula to find a keyword in the header row:

=OFFSET($A$2,,MATCH("THIS",$1:$1,0),COUNTA($A:$A)-1)

My issue is the COUNTA statement at this point. I want to type something like COUNTA(COLUMN(MATCH("THIS",$1:$1,0))) but it doesn't appear to be this simple.

Instead my workaround is something to the effect of:

COUNTA(INDIRECT(LEFT(ADDRESS(1,MATCH("THIS",$1:$1,0)),2)&":"&LEFT(ADDRESS(1,MATCH("THIS",$1:$1,0)),2)))-1

The entire formula becomes rather long and cumbersome, and I have a feeling that I might be missing something to simplify it. Is there an easier way to do this that would be similar to simply evaluating to COUNTA(Column(10)) or is my approach the most efficient method?

Answer 1

Try this definition

=OFFSET($A$2,,MATCH("THIS",$1:$1,0)-1,COUNTA(OFFSET($A:$A,,MATCH("THIS",$1:$1,0)-1))-1)

The second OFFSET gets the whole column
