What is this tool for?
Lists of emails, keywords, names or product codes often contain repeated entries after merging several sources. Removing duplicate lines keeps each entry once, in the order in which it first appeared.
It is handy for lists of names, emails, keywords or product codes, and for fixing paragraphs that came out cut into short lines. Everything runs in your browser and your text is never uploaded.
Limits to keep in mind
- Duplicates are lines that are exactly equal, so “Apple” and “apple” count as different.
- Sorting treats numbers naturally (2 before 10) and follows the rules of the page language.
