Does this upload my text?

No. All sorting happens in your browser via Array.sort(). Your text never touches a server.

How does it handle mixed Chinese + English?

We use the browser's Intl.Collator with locale-sensitive comparison. Chinese characters sort by Unicode codepoint, which roughly matches pinyin for common characters.

What's the difference between numeric and alphabetical?

"10" sorts before "2" alphabetically (string comparison), but after "2" numerically. Pick numeric for lists of numbers, alphabetical for text.

Why "trim whitespace"?

A line with trailing spaces sorts differently from one without. Trim removes them so visually-identical lines group together.

Does sorting preserve blank lines and indentation?

Blank lines are treated as empty strings, so they cluster at the top of an A-Z sort. Leading indentation counts as part of the line unless you enable "trim whitespace", so " apple" sorts before "apple" because the space has a lower codepoint. If you want code or YAML to keep its structure, sort a flat list of values instead of an indented block.

Alphabetize a 200-name attendee list before a CSV import

You exported 200 RSVP names from a Google Form, but they came back in signup order. Paste the column here, sort A-Z, turn on "remove duplicates" to drop the 6 people who registered twice, and you get a clean 194-line list ready to paste back into your CRM in under a minute, no spreadsheet formula needed.

Sort error codes numerically instead of as strings

A log dump gave you HTTP-style codes like 2, 10, 100, 404, 500. Alphabetical sort puts "100" before "2", which scrambles the order. Switch to numeric sort and they line up 2, 10, 100, 404, 500 so you can scan for the gaps and spot which status range your service is missing handlers for.

Find the longest lines in a config or copy file

A teammate sent a 90-line properties file and one value is blowing past an 80-character limit. Sort by length descending and the offenders float to the top. You immediately see the three lines over 120 chars and fix them, instead of eyeballing all 90 rows one at a time.

Reverse a chronological changelog into newest-first

Your CHANGELOG was built bottom-up, oldest entry at line 1. Paste the whole thing, hit reverse, and the newest release lands at the top, exactly the order readers expect, without re-sorting by date strings that mix "2026-01" and "2026-1" formats inconsistently.

Common pitfalls

Using alphabetical sort on a list of numbers — "11" lands before "2". Switch to numeric sort whenever every line is a number, like prices or IDs.
Forgetting case sensitivity — by default "Zebra" sorts before "apple" because uppercase Z (codepoint 90) beats lowercase a (97). Turn off case-sensitive sorting to get apple, Zebra in the order you expect.
Sorting an indented YAML or code block and breaking its structure — only the line text moves, so nesting scrambles. Sort a flat list of values, then paste them back into the structure by hand.

Privacy

Every sort runs in your browser through Array.sort() with the Intl.Collator API. Your text is never uploaded and never logged. The one thing that does leave your machine: if you use the share link, the input lines are encoded into the URL so the recipient sees the same result, so don't share links for confidential lists. Plain sorting in this tab keeps everything local.
