FAQ
Does this remove duplicates while keeping the original order?
Yes—by default it keeps the first occurrence and removes later duplicates. Enable Sort unique if you want alphabetical output instead.
Can I remove duplicates from a comma-separated list?
Yes. Set Input separator to Comma, then run the tool.
How does “Ignore case” work?
When enabled, items like Apple and apple are treated as the same duplicate, and the first version is kept.
What does “Trim items” do?
It removes leading/trailing spaces before comparing items, so apple and apple match.
Will empty lines be removed?
Yes if Remove empty is enabled. Turn it off if you need to keep blanks as items.
Can I use a custom separator like | or tab?
Yes. Choose Custom and enter your separator (supports \t, \n, \r).
Is my text sent to a server?
No. The deduplication runs locally in your browser and does not make network requests.
