Frequently asked questions
Can it remove duplicate lines?
Yes. Turn on the remove-duplicates option and every repeated line is reduced to a single occurrence; you can combine it with sorting and blank-line removal to clean a list in one step.
Is my list uploaded anywhere?
No. Sorting and de-duplication happen entirely in your browser — the text you paste is never sent to or stored on a server.
