Remove empty lines and spaces in Notepad++?

回答1

To get rid of leading space(s) and all empty lines (even if the empty line contains spaces or tabs)

1. Go to Search -> Replace
2. Select "Regular expression" under Search mode.
3. Use ^\s* for "Find what" and leave "Replace with" blank.
4. Click Replace all

Regex explanation:

• ^ means beginning of the line
• \s* means any number (even 0) of whitespace characters. Whitespace characters include tab, space, newline, and carriage return.
