How It Works

Paste your raw text or list into the input box. The tool scans every line in real-time, instantly identifying and removing redundant entries. Check the options to ignore case or trim whitespace for more aggressive cleaning before copying the result.

Frequently Asked Questions

Does it preserve the original sorting order? ▾

Yes. Unlike some primitive tools that force an alphabetical sort to remove duplicates, our tool maintains the chronological appearance of the first unique instance of every line.

Can I ignore capitalization when removing duplicates? ▾

Yes, you can toggle the 'Ignore Case' option to treat 'Apple' and 'apple' as the exact same line, effectively removing one of them.

Is my pasted data stored anywhere? ▾

No. All text processing occurs safely and privately within your own web browser. No data is sent to our servers.
