Solution 2 - Replace

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:)

Solution 3 - Replace

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).

Solution 4 - Replace

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

Solution 5 - Replace

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.

Solution 6 - Replace

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
