[replace] Notepad++ - How can I replace blank lines

I have a text file with a thousand lines of numbers like so:

402

115

90

...

As you can see there is a blank line in between each number that I want to remove so that I have

402
115
90
...

How can I do this?

This question is related to replace notepad++ blank-line

The answer is


You can record a macro that removes the first blank line, and positions the cursor correctly for the second line. Then you can repeat executing that macro.


By the way, in Notepad++ there's built-in plugin that can handle this: TextFX -> TextFX Edit -> Delete Blank Lines (first press CTRL+A to select all).


This will remove any number of blank lines

CTRL + H to replace

Select Extended search mode

replace all \r\n with (space)

then switch to regular expression and replace all \s+ with \n


This should get your sorted:

  • Highlight from the end of the first line, to the very beginning of the third line.
  • Use the Ctrl + H to bring up the 'Find and Replace' window.
  • The highlighed region will already be plased in the 'Find' textbox.
  • Replace with: \r\n
  • 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look: enter image description here


As of NP++ V6.2.3 (nor sure about older versions) simply:

  1. Go menu -> Edit -> Line operations
  2. Choose "Remove Empty Lines" or "Remove Empty Lines (Containing white spaces)" according to your needs.

Hope this helps to achieve goal in simple and yet fast way:)
