How to Use
Paste the text on the left, one item per line.
Choose sort (alphabetical, by length, or shuffle), case, trim, drop empty, dedupe, reverse, and number — combine as needed.
The result updates live on the right. Original and final line counts are shown; copy in one click.
FAQ
In what order are options applied?
1) trim → 2) drop empty → 3) case → 4) sort (or shuffle) → 5) reverse → 6) dedupe → 7) number. This order produces the most predictable result.
How is sort done across scripts?
It uses the browser's `localeCompare`, so Hangul, English, and digits sort in a natural locale-aware order.
Is dedupe order-aware?
Yes. With sort, identical items group up and one of each remains. Without sort, dedupe preserves first-seen order and removes later duplicates.
Is shuffle truly random?
It uses Fisher–Yates with Math.random(). Not cryptographically random, but plenty for raffles or test data.
Is anything sent to a server?
No. All processing happens in your browser; nothing leaves the page.
