Why Clean

Frequently asked questions
Is this tool free?
Yes. Clean is free, with no account, payment or download gate.
Is my data uploaded?
No. Processing happens in your browser. Your input is not sent to our servers, sold, shared or used for AI training. Large inputs are limited by your device’s available memory.
Can I sort Z to A?
Yes. Switch between ascending A–Z and descending Z–A.
Can I sort by surname?
Last-word sorting compares the final word of each item. This is useful for many names but does not identify compound surnames or every naming convention.
Does it remove duplicates?
Only when you turn on Remove duplicates. Ignore-case mode treats Apple and apple as duplicates and keeps the first spelling.
Which separators work?
New lines, commas, semicolons and tabs. Output uses one item per line.
