How to remove duplicates from a list
Have a list of emails, URLs, IDs or codes with repeated entries? Our tool removes them in one click, preserving the order of first appearance. The options handle common cases: ignore case, trim whitespace, and sort alphabetically.
Typical use cases
- Clean email lists before a send
- Remove duplicate URLs from a sitemap or crawler
- Unify lists of promo codes or SKUs
- Depurate logs or data exported from databases
Frequently asked questions
Is the line order preserved?
Yes, by default unique lines keep their first-appearance order. If you enable "Sort alphabetically" they will be sorted instead.
