List Shuffle
Free online list shuffle tool. Randomly reorder items using the Fisher-Yates algorithm with custom separators and result limit. No signup, 100% browser-based for complete privacy.
How does the list shuffle tool work?
Paste or type your list items, and the tool uses the Fisher-Yates algorithm to randomly reorder them. Every possible arrangement has an equal chance of appearing.
What is the Fisher-Yates shuffle algorithm?
Fisher-Yates (also called Knuth shuffle) is a classic algorithm for generating a random permutation. It guarantees that every possible ordering is equally likely, making it perfectly unbiased.
Is my data private and secure?
Yes. All processing happens locally in your browser. No data is ever sent to any server, so your lists remain completely private.
What are common use cases for list shuffling?
Common uses include organizing raffles and giveaways, creating randomized seating charts, dividing teams fairly, generating random samples, and making unbiased decisions.
Can I use custom separators between items?
Yes, you can choose from multiple separator types including newlines, commas, semicolons, and more to match how your list is formatted.
How does the result limit feature work?
Set a limit number to return only that many items from the shuffled result. Useful for picking a specific number of winners or selecting random samples.
Are duplicate values preserved after shuffling?
Yes, all items including duplicates are preserved. If your input contains A, A, B, the output will still contain two A's and one B in a random order.
Is the shuffle truly random?
The algorithm itself is mathematically perfect. It uses JavaScript's Math.random() which provides good statistical randomness suitable for everyday use, though not cryptographically secure.
Is this tool free to use?
Yes, the tool is completely free with no registration or sign-up required. You can use it as many times as you need.
Does it work offline?
Yes, since all processing happens in your browser, the tool works even without an internet connection once the page is loaded.
