Line sorter & deduplicator
Paste a list of lines and run operations in order: trim, drop empties, filter, dedupe, sort, add prefix/suffix. Live stats show lines in vs out.
Your data never leaves the browser — all processing runs locally.
Input
Operations (applied top to bottom)
Sort
Natural sort treats item2 before item10. Shuffle uses crypto.getRandomValues.
Output
lines in lines out duplicates removed
About this tool
Handy when cleaning log exports, URL lists, email addresses, or any newline-separated blob. Operations stack in a fixed order so results are predictable — trim and filter before deduping, sort last (except prefix/suffix, which runs after sort).
