Sort & Dedupe Lines
Sort, dedupe, and reverse lines of text
Why sort lines in the browser?
Sorting and deduplicating a list is a 5-second job at the command line (`sort -u`), but you don't always have a terminal handy — pasting from a spreadsheet column, cleaning up a list of imports, deduplicating email addresses scraped from a page. This tool does it in the browser with no upload.
Sorts use the browser's native locale-aware comparison, so `é` sorts near `e` rather than at the end of the alphabet. Numeric sort isn't smart — '10' sorts before '2' lexicographically — so prefix numbers with zeros if numeric ordering matters.

Is the sort case-sensitive?
Optional. The default is case-insensitive (so 'Apple' and 'apple' end up adjacent). Toggle the case-sensitive option if you want strict ordering.
Does it sort numbers correctly?
Lexicographic sort treats '10' as less than '2'. For true numeric sort, pad numbers with leading zeros first.
How is dedup detected?
Exact line match after optional case normalisation. Whitespace is significant — ` apple` and `apple` are different lines.
Are blank lines kept?
Sorted with everything else by default. Strip them first if you want them removed.
Is the data sent anywhere?
No — sorting happens entirely in your browser.
