Removing empty lines in Notepad++

Question

How can I replace empty lines in Notepad++? I tried a find and replace with the empty lines in the find, and nothing in the replace, but it did not work; it probably needs regex.

Answer 1

There is now a built-in way to do this as of version 6.5.2

Edit -> Line Operations -> Remove Empty Lines or Remove Empty Lines (Containing Blank characters)

Answer 2

You need something like a regular expression.

You have to be in Extended mode

If you want all the lines to end up on a single line use \r\n. If you want to simply remove empty lines, use \n\r as @Link originally suggested.

Replace either expression with nothing.
