Line Tools – Dedupe, Sort & Clean Up Lists
Paste any line-based text — names, lists, keywords — and click a button to clean it up. Chain several actions in a row, and undo if you click the wrong one.

What you can do
- Remove duplicate lines from email lists, keyword lists or log output, keeping the first occurrence in its original order.
- Sort alphabetically with natural number order (item 2 before item 10), by the number in each line, or by length.
- Join and split: turn a column copied from a spreadsheet into a comma-separated line, or the other way round.
- Filter to keep or drop lines containing a word, and find & replace across all lines.
Tips
Run "Trim spaces" before "Remove duplicates" so lines that differ only by trailing spaces are treated as the same. Every action can be undone, up to 50 steps.
FAQ
Is the duplicate check case-sensitive?
Yes. To ignore case, click "lowercase" first, then remove duplicates.
