Stacking multiple columns on to one?

Question

I am using Google SpreadSheet, and I\'m trying to have multiple sheets containg a list of words. On the final sheet, I would like to create a summative list, which is a comb

Answer 1

The basic way, is just to do it as arrays like so

={A1:A10;B1:B10...etc}

The problem with this method, as I found out is that its very time consuming if you have lots of columns. I've done some searching around and have come across this article:

Joining Multiple Columns Into One Sorted Column in Google Spreadsheets

The core formula is

=transpose(split(arrayformula(concatenate(if(len(A:Z)>0,A:Z&";",""))),";"))

Obviously you'd replace the A:Z to whatever range you want to use. And if you want to do some sorting or removing duplicates, you'd simply wrap the the above formula in a SORT() and/or UNIQUE() method, like so..

=sort(unique(transpose(split(arrayformula(concatenate(if(len(A:Z)>0,A:Z&";",""))),";"))))

Hope this helps. Happy coding everyone :)
