Line Sorter / Deduplicator

Sort lines, remove duplicates and use natural or case-sensitive ordering.

How to use the Line Sorter and Duplicate Remover

1. Paste one item per line (hostnames, IDs, emails, log lines), or click Sample.
2. Choose how to sort and what to do with duplicates. The result updates as you type.
3. Copy or download the lines.

Sorting

• Natural compares numbers by value: server-2 comes before server-10.
• Dictionary uses your language's alphabetical order, so accented letters sort where you'd expect.
• Code point matches LC_ALL=C sort: uppercase before lowercase, digits and punctuation by their character codes.

Duplicates

• Remove (keep first) is like sort -u. Unless Case-sensitive is on, Server-2 and server-2 count as the same line.
• Keep only lines that appear once is like uniq -u: every repeated line is dropped entirely.
• Count is like sort | uniq -c, prefixing each line with how often it appears.
