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

1. Edit >> Blank Operations >> Trim Leading and Trailing Spaces (to remove black tabs and spaces in empty lines)
2. Ctrl + H to get replace window and replace pattern: ^\r\n with nothing (select regular expression)

Note: step 1 will remove your code intendation done via tabs and blank spaces

Answer 2

1. notepad++
2. Ctrl-H
3. Select Regular Expression
4. Enter ^[ \t]*$\r?\n into find what, leave replace empty. This will match all lines starting with white space and ending with carriage return (in this case a windows crlf)
5. Click the Find Next button to see for yourself how it matches only empty lines.
