How the duplicate remover works

Paste your list, one entry per line, and press "Remove duplicates." The tool keeps the first time each line appears and deletes every repeat after it, so your original order stays intact.

Turn on "Ignore case" if entries like "Apples" and "apples" should count as the same item. Leave it off if capitalization matters for what you're comparing.
