Free Duplicate Line Remover & Text Sorter
Cleaning a list by hand is tedious. Paste your text and this tool removes duplicate lines, sorts them A to Z or Z to A, sorts by length, reverses the order, trims extra spaces and deletes blank lines.
It is handy for email lists, keyword lists, log files, CSV columns and anything else with one item per line. Everything runs in your browser, so private data stays private.

Tips for the best results
- Turn on case-insensitive matching to catch “Apple” and “apple”.
- Trim spaces first so lines that differ only by whitespace are merged.
- Use “Reverse order” to flip a list, or “Numeric” to sort numbers correctly.
- Combine trimming with “Remove empty lines” for the cleanest list.
Common mistakes to avoid
- Forgetting that lines differing by a space are different.
- Sorting numbers as text (10 comes before 2).
- Pasting a list with mixed line endings from spreadsheets.
