Sort & Dedupe Lines
Sort, deduplicate, shuffle, and clean a list of lines
About Line Sorting
A simple but commonly needed tool: take a list of lines and sort, deduplicate, or clean them. Useful for tidying up word lists, log entries, todo lists, CSV columns, or anywhere you need a clean unique-and-sorted set of strings.
Sorting uses locale-aware comparison so accented characters and Unicode are ordered correctly. Deduplication keeps the first occurrence of each line. Everything runs in your browser; nothing is sent over the network.
Frequently asked questions
Does it preserve the original order on duplicates?
When deduplicating, the first occurrence of each line is kept and subsequent duplicates are removed. Sorting is then applied to the deduplicated list.
How big a list can it handle?
Tens of thousands of lines should process instantly in any modern browser. Larger files may briefly hang the tab while sorting.
