That helped, but what was causing the merging problem is some of the empty lines separating each adressee aren't actually empty. About 450 of these lines contained 1 or more spaces. After applying your last command, it left them with 1 space, which still caused merging of addresses into a single cell. What's needed in this case is to make the separating blank line with 1 space into an actual blank line with no single space. Without wildcards, I did this:

Find = ^p ^p
Replace = ^p^p

And that did the trick! Everything worked as intended. Mr. Edstein, you are my new hero. That was my 47th b-day present (it's still Nov. 12 here in Brazil )
