Overview: Text Sort / Unique sorts and deduplicates text line by line. It supports ascending, descending and random ordering, and offers optional case sensitivity, duplicate removal and natural sort so that item2<item10. It is a great tool for line-oriented data such as configuration entries, word lists, log lines or code snippets.

How to use: Step 1 — paste the text you want to sort on the left (one item per line). Step 2 — pick the sort mode in the toolbar: A→Z is ascending, Z→A is descending, "Shuffle" randomises the order. Step 3 — tick "Case-sensitive" to sort with case (uppercase letters come first) or leave it off to compare after lower-casing; tick "Remove duplicates" to keep only the first occurrence of each line; tick "Natural sort" so that item2<item10 instead of dictionary order. Step 4 — the right panel shows the result live.

Typical scenarios: Organise IP allow-lists, domain lists or word lists alphabetically; deduplicate column names exported from a database for documentation; shuffle lottery names or question banks; sort package.json dependencies; count unique error lines from log analysis; sort file-name lists in natural order.

Technical notes: Sorting uses JavaScript’s localeCompare (with { numeric: true } for natural sort) which handles mixed Chinese/English correctly. Shuffling uses the Fisher-Yates algorithm for a uniform distribution. Deduplication uses a hash set for good performance. Blank lines participate in sorting and deduplication as normal lines. Only the order of lines is changed — line content is preserved.

Privacy: Sorting, deduplication and shuffling all happen locally in your browser and no text is uploaded, so it is safe to use with internal lists or word lists.
