Sort Lines

1. 1Paste your lines.
2. 2Choose a sort method and direction.
3. 3Turn on natural sorting if your lines contain numbers.
4. 4Copy the sorted result.

Alphabetical sorting uses your browser's locale-aware comparison, which orders accented characters the way the language expects — so 'é' sorts next to 'e' rather than after 'z', which is what a plain byte comparison would do.

Natural sorting is the option most people actually want when their lines contain numbers. A plain alphabetical sort puts item10 before item2, because it compares character by character and '1' comes before '2'. Natural sorting reads runs of digits as numbers, giving item2, item10, item100 — the order a human would use.

The random option uses a Fisher-Yates shuffle driven by cryptographic randomness, which produces a genuinely uniform permutation. Sorting by a random key, the common shortcut, does not.
