About Remove Duplicate Lines

Clean up any list by removing duplicate lines while preserving the order of the first occurrence. Optionally trim surrounding whitespace and ignore letter case so near-identical lines are matched too. The tool reports how many duplicates were removed and runs entirely in your browser.

How to use

  1. 1

    Paste your list or text into the box.

  2. 2

    Choose whether to trim whitespace and ignore case.

  3. 3

    Copy the de-duplicated result.

Frequently Asked Questions

Yes. The first time a line appears it is kept in place; only later duplicates are removed, so your ordering stays intact.
