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 r

Answer 1

A few of the above expressions and extended expressions did not work for me, but the regular expression "$\n$" did.

Answer 2

I did not see the combined one as answer, so search for ^\s+$ and replace by {nothing}

^\s+$ means
  ^ start of line
  \s+ Matches minimum one whitespace character (spaces, tabs, line breaks)
  $ until end of line

Answer 3

this work for me:

SEARCH:^\r  
REPLACE:            (empty)

Answer 4

Well I'm not sure about the regex or your situation..

How about CTRL+A, Select the TextFX menu -> TextFX Edit -> Delete Blank Lines and viola all blank line gone.

A side note - if the line is blank i.e. does not contain spaces, this will work

Answer 5

CTRL+A, Select the TextFX menu -> TextFX Edit -> Delete Blank Lines as suggested above works.

But if lines contains some space, then move the cursor to that line and do a CTRL + H. The "Find what:" sec will show the blank space and in the "Replace with" section, leave it blank. Now all the spaces are removed and now try CTRL+A, Select the TextFX menu -> TextFX Edit -> Delete Blank Lines

Answer 6

An easy alternative for removing white space from empty lines:

1. TextFX>TextFX Edit> Trim Trailing Spaces

This will remove all trailing spaces, including trailing spaces in blank lines. Make sure, no trailing spaces are significant.
