How it works

Lines are sorted with localeCompare for natural alphabetical ordering. Numeric mode uses parseFloat per line; non-numeric lines fall back to lexical order. Dedupe runs after sort and uses the same case rule.

How to use it

  1. Paste the list

    Drop in any list of lines: contacts, IDs, TODOs, log entries. Mixed alphanumeric content is fine.

  2. Pick mode and direction

    Alphabetical uses localeCompare for natural order. Numeric uses parseFloat. Choose ascending or descending.

  3. Toggle case and dedupe

    Case-sensitive separates A from a in the order. Dedupe removes duplicates after sorting, in one pass.

  4. Copy the sorted list

    Take the ordered output into your spreadsheet, your config file, or any process where stable line order matters.

Use cases

Alphabetise an exported contact list.

Sort numeric IDs from a database dump.

Tidy a TODO list by description.
