Merging two lines into one - Notepad++

Question

I have a line like this

assignee: Akebono Brake Industry Co. Ltd.  , 
 Fujitsu Limited  application_no: 06/946,825

I want the output to be

assignee: Akebono Brake Industry Co. Ltd.  , Fujitsu Limited  
application_no: 06/946,825

To bring the application_no: 06/946,825 to the next line, I can find application_no: and replace it with \napplication_no: in my NOTEPAD++

But, how can I bring that string that spans to next line back to the first line? I mean what should I do to get the Fujitsu Limited to the line starting with assignee:

Any guidance please?

Answer 1

Since Extended is the only mode that handles the newlines correctly but you need to match with regular expressions, you will need to do this in two steps.

First, use a regex find and replace to add some recognizable token to the beginning of each line you want to move up, I used 'MATCH' but you could definitely change this.

Then, switch to Extended to search for a newline followed by the token, and replace it with an empty string to delete both the line break and the token.
