Remove duplicates FAQ
Common questions
What does remove duplicates mean?
It means scanning a list or text block and keeping only the first unique version of each repeated line.
Does this remove duplicates tool upload my text?
No. The duplicate removal runs in your browser, so your text is not sent to a server.
Can it remove duplicates while ignoring uppercase and lowercase?
Yes. Enable ignore case to treat lines such as Apple and apple as the same value while preserving the first version.
Can I remove empty lines too?
Yes. Empty lines are removed by default. Turn on keep empty lines when you want one blank line preserved.
Is this only for small lists?
It works well for everyday lists, keyword sets, spreadsheet rows, and text cleanup tasks directly in the browser.
