combinatorics with words

Hello gurus,

I've attached a spreadsheet with x columns. Each column has a list of words or symbols.


I'd like an "output" which provides me with a concatnation of every possible combination of the cells in the specified range.

The spreadsheet illustrates "the beginning" of the output.

Each column will not necessarly have the same number of rows. So some concatnations will be shorter than others.

I'll appreciate the help!
