Alphabetize a List

A plain alphabetical sort compares characters one at a time, which produces the familiar wrong answer: “Chapter 1, Chapter 10, Chapter 11, Chapter 2”. This tool uses a locale-aware comparison that recognises digits as numbers, so you get “Chapter 1, Chapter 2, Chapter 10, Chapter 11”.

The same comparison handles accented and non-English letters properly, sorting them with their base letter rather than dumping them at the end of the list.

Less obvious but genuinely useful: sorting by length puts the outliers at the ends. For keyword lists, the longest lines are your long-tail phrases. For a list of headlines, the longest are the ones that will be truncated. For data, an unexpectedly short line is often a row that failed to export properly.
