What this tool does
Remove Duplicate Lines finds repeated rows in plain text and keeps one copy, with cleanup options for common list noise.
How it works
Paste a list, choose how strict matching should be, and copy the deduplicated result.
Useful for
- Deduplicate email addresses, names, or IDs.
- Clean repeated keyword and tag exports.
- Remove copied list repeats before sorting or sharing.
Questions before the button mashing
Does line order stay the same?
The usual cleanup keeps the first copy of each line and preserves the original order.
Can blank lines be removed too?
Yes. Blank-line cleanup belongs naturally with deduping and helps keep the final list compact.
