What is List Shuffler?
This shuffler randomly reorders input list items. Supports multiple delimiters: newline (default), comma, semicolon, space, and more. Uses the Fisher-Yates shuffle algorithm to ensure true randomness. Results update in real time, ready to copy with one click. Perfect for lotteries, random grouping, test data generation, and game randomization. All processing runs locally in your browser — your list content is never uploaded.

What is this list shuffler?
An online list randomization tool. Input: list items (one per line or separated by delimiter). Output: the list in random order. Used for lotteries, grouping, and test data. All processing runs locally in your browser.
What randomization algorithm does it use?
It uses the Fisher-Yates shuffle algorithm (also called Knuth shuffle). This is the industry-standard algorithm for random permutations, ensuring each permutation is equally likely — truly random.
What delimiters are supported?
Newline (default, one item per line), comma, semicolon, space, tab, and more. You can also specify a custom delimiter.
Is each shuffle result different?
Yes. Each click of the "Shuffle" button generates a new random permutation. It uses the browser's cryptographically secure random number generator (crypto.getRandomValues) to ensure randomness.
How many items can it handle?
Theoretically unlimited, but keep it under 10,000 items for best performance. Large datasets may take a few seconds on lower-end devices.
Is my list content uploaded?
No. All randomization happens locally in your browser. Your list content never leaves your device.
