I just tried it and it was working at 63 characters. Checked with 112 characters all the same and it did not sort those by the 113th character. To me, 63 characters is not all that short.

I expect that someone here will provide a macro that does more. I remember doing bubble sorts in my computer science class, but that was a long time ago. If you do not get a response here in the next couple of days, try posting in the Word VBA Forum. Do wait, though, or close this question and post there.
