Is there a simple way of removing linebreaks in Notepad++?

For example:

This text has been splitted
in lines, and it's longer than
3200 words, so it would be great
to find and replace line breaks
like these.

    Hmm, in VI it would be just typing 4J

  • If you are looking to compose something like a URL from putting the URI parameters on multiple lines, then this answer is a bit more helpful: stackoverflow.com/a/13990281/501113 Aug 19, 2015 at 15:37
  • Do you expect spaces added: "This text has been splitted in lines, and it's longer than 3200 words..." or no spaces added: "This text has been splittedin lines, and it's longer than3200 words..." Each result requires a different technique.

  1. Highlight the lines you want to join (or use Ctrl + A to select everything)
  2. Choose Edit → Line Operations → Join Lines from the menu or press Ctrl + J.

It will put in spaces automatically if necessary to prevent words from getting stuck together

  • Tip: You might need to hit CTRL + J more than once. Do not use >View >Word wrap, to better see the linebreaks.

    how can I disable adding spaces? Mar 7, 2017 at 21:17


In Search Mode pick Extended

Find - \r\n Replace - leave it empty.

    I believe it needs to be \r\n since this is for Windows.

    It should be \r\n and the replace field should contain one space character.

  • @JamesP, what is the difference? And why so in Windows?

    @user1993: The Wikipedia article en.wikipedia.org/wiki/Newline has detailed information about how linebreaks work on different operating systems.

For me, using Win 7, I had to use


in the Find box and type in <space> in the Replace box so that there is a single space between the last word of the current line and the first word of the next line.

  • Did you mean \n

    No, I mean \r. \n does nothing on my system.
