How to use the Duplicate Line Remover

Paste your list, one item per line.
Choose whether the check should be case-sensitive.
Click Remove duplicates and copy the cleaned list.

Tips

Leave case-sensitive off if "Example" and "example" should count as the same line.
This checks for exact line matches — extra spaces or slightly different wording won't be caught as duplicates.
