- Ctrl + H
- Check “Regular Expression”
- Search for
\n\n
- Replace with
\n
- Click “Replace all” until all lines are deleted
If you want to keep a blank line you should:
- Search for

- Replace with
\n\n
If you want to replace consecutive lines that are not empty but contain whitespaces only you should:
- Search for
\n[\t\r]+$\n
- Replace with
