Sort lines alphabetically
Put a list of lines into alphabetical order.
What to know
Sorting is natural rather than purely alphabetical, so item9 comes before item10 instead of after it. Plain string sorting gets this wrong on any list with numbers in it.
Comparison is locale-aware, which orders accented characters the way a reader would expect.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
