I did not know PTC had a workaround for this - nice find!
Unfortunately the PTC recommendation is pretty user intensive for what should be a simple task. I would still recommend a p-Shell / Pro/TOOLKIT application to tackle this. You will get with better quality and without having to introduce the human factors for formatting in MS-Excel manaually. (what a pain)
Just a suggestion - we may do an article on this subject soon as it is an interesting one.
