Although it can easily be accomplished with VBA Macro - I would suggest
another approach:
1) In the picture - the long formula is an array formula, and is to be
confirmed with CTRL+SHIFT+ENTER rather than with simply ENTER.
The curly brackets {} are not to be typed manually, those are entered by the
€œExcel€�, when the formula is entered as an Array formula.
2) Column "C" and on maybe hidden but not deleted !

3) In order to use the MCONCAT function you will have to install the
MOREFUNC add-in:
