About Remove Duplicate Lines
Paste your list and every repeated line disappears, keeping the first occurrence and the original order. A case-insensitive mode treats 'Apple' and 'apple' as the same line — toggle it in the Duplicates section.
Handy for cleaning CSV exports, log files, email lists and keyword lists. De-duplication runs locally in your browser on every keystroke — nothing is uploaded.
