Notepad++ How to delete carriage return in lines without full stops only

Question

I have documents that contain carriage returns in the middle of sentences, like this:

Were there any connections? Or
was all of it

I have found a regex for finding these lines (Find: \w$) and I can insert a full stop if I want (Replace: $0.) but what do I do to insert a space and remove the carriage return/delete it instead so it becomes this:

Were there any connections? Or was all of it

I have a lot of these to replace so it would be helpful to get a replace command that takes care of all of them.

Is there a way to do this?

Answer 1

• Ctrl+H
• Find what: (?<=\w)\R(?=\w)
• Replace with: A space
• CHECK Wrap around
• CHECK Regular expression
• Replace all

Explanation:

(?<=\w)     # positive lookbehind, make sure we have a word character before
\R          # any kind of linebreak
(?=\w)      # positive lookbahead, make sure we have a word character after
