Free No signup Client-side Privacy friendly Updated

How to use

  1. 1 Paste one item per line.
  2. 2 Pick a sort mode — alphabetical, numeric, by length, or just reverse.
  3. 3 Toggle case-sensitive, locale-aware, trim, and unique as needed.
  4. 4 Copy the sorted result.

Why use this tool

  • Numeric mode parses the leading number per line, so 2 comes before 10 (not after).
  • Locale-aware sort uses Intl.Collator — the same comparison your OS file manager uses.
  • Length sort is handy for finding the longest or shortest entry in a list.
  • Reverse flips order without comparing anything.

Frequently asked questions

Why does alphabetical sort give 1, 10, 100, 2, 20?

That is correct alphabetical order — character "1" comes before "2". Switch to Numeric ascending for true number order.

What if a line has no number in numeric mode?

Lines without a parseable number get pushed to the bottom and ordered alphabetically among themselves.

Does Unique remove case-insensitive duplicates?

It respects the Case-sensitive toggle — if off, apple and Apple are treated as the same line.
