UlvixorDuplicate Line Remover
Remove repeated lines from a list or text while always keeping the first occurrence and the original order of the remaining lines. Perfect for cleaning up email lists, names, or records without shuffling them.
How it works
- Paste the text or list, one item per line.
- The tool goes through the lines in order and keeps only the first occurrence of each one.
- Enable 'Case-sensitive' if you want 'Email@mail.com' and 'email@mail.com' to be treated as different lines.
- Check how many duplicate lines were removed, then copy or download the result.
Use cases
- Clean up an email list before importing it into a bulk-sending tool.
- Remove repeated rows from data exported as plain text from a spreadsheet.
- Clean up a to-do list, set of keywords, or tags that has accumulated duplicates over time.
- Merge lists from multiple sources without losing the order in which items appeared.
