Frequently asked questions
What sort orders are available?
You can choose alphabetical/dictionary order (ascending), reverse (descending), or by character length. Korean, English, and numbers mixed together are still sorted in dictionary order.
How does duplicate-line removal work?
When several identical lines exist, only the first is kept and the rest are removed. Turning on "Ignore case" treats uppercase and lowercase as the same line.
Is the text I enter sent to a server?
No. All processing happens inside your browser, and your text is never sent to any external server.
