Line Sorter

The Line Sorter reorders a list of lines alphabetically (A-Z or Z-A), by length (shortest or longest first), numerically, or shuffles them into random order — with optional duplicate removal and blank-line stripping applied on top of any sort. It's a one-paste alternative to opening a spreadsheet just to click a sort button.

It's used for alphabetizing a list of names or references before publishing, sorting a set of keywords or tags by length to find the shortest ones for a character-limited field, numerically ordering a column of IDs or scores that would sort wrong as plain text (where '10' sorts before '2' alphabetically), and shuffling a list of raffle entries, quiz questions or team names into random order for a fair draw. Combined with duplicate removal, it also works as a quick way to get a sorted, deduplicated list in a single pass rather than sorting and deduplicating separately.

Numeric sorting extracts the leading number from each line and sorts by that value, so a line like '10 items' sorts correctly as ten, not as the string '10' compared character-by-character against '2 items' — the exact failure mode that makes plain alphabetical sort put '10' before '2'. Random shuffling uses a proper randomized in-place shuffle (each position has an equal chance of landing anywhere), not a naive sort-by-random-key approach, which can be measurably biased for smaller lists.

Case-insensitive sorting treats 'Apple' and 'apple' as equivalent when deciding order, which matches how most people expect an alphabetized list to read — without it, every uppercase letter sorts before every lowercase letter in standard string comparison, which can put 'Zebra' before 'apple' in a way that looks wrong to a human reader even though it's technically correct ASCII order. Sorting runs entirely in your browser.
