Frequently asked questions
What counts as a 'blank line' in this tool?
Both completely empty lines and lines containing only spaces, tabs, or other whitespace characters are treated as blank and removed.
Will this tool change the spacing within non-blank lines?
No, it only removes lines that are entirely blank; the content and formatting of every other line stays untouched.
Can I use this to clean up a CSV or config file?
Yes, removing stray blank lines is a common step before importing CSV files or config files into other systems that don't tolerate empty rows.
Is there a size limit on the text I can clean?
No practical limit, since everything is processed locally in your browser rather than through a server.
Does removing blank lines affect intentional paragraph spacing?
Yes, since paragraph breaks in prose often rely on blank lines, removing them will merge paragraphs — use with care on formatted prose.
Is my document uploaded when I use this tool?
No, all processing happens locally in JavaScript in your browser and nothing is sent to a server.
