Extremely simple to do, in fact, so no problem.

Literally like this?

1 blah blah blah blah blah,

2 blah BLAH blah blah-blah.

3 bla blah blah Blahhhhhh blah <long line>
blah blah blah.

4 and blah?

How would you like the numbers formatted?

Later I'll put this in my coding area, with a proper little write-up, but for now this URL:

... will launch the program for you. You may get a warning that it's signed by an unknown publisher. That's ok, it's me  :Thmbsup:

Instructions:

1. Select and copy the text that is to be re-formatted so it's in your PC's (or Mac or Linux box) clipboard
2. Click the 'Paste' button or use Ctrl+V in the top window
3. Click the 'Go' button
3a. Go "ooh" and "aah" in admiration (optional step)
4. Select a subset of the results, or leave everything unselected (which gets you all text in the results area), and click the 'Copy' button - your formatted text is now available on the clipboard to do whatever-it-is-you-need-to-do with it.
