About the Algorithm
This tool uses the Fisher-Yates (Knuth) shuffle algorithm, which guarantees a perfectly uniform random distribution. Every possible permutation has an equal probability of occurring.

What is a List Shuffler?
A list shuffler is a tool that randomizes the order of items in a list. This is useful for creating random sequences, fair selections, or simply mixing up the order of things for variety.
Our list shuffler uses the Fisher-Yates (also known as Knuth) shuffle algorithm, which is the gold standard for producing truly random permutations. This algorithm ensures that every possible ordering of your list has an equal probability of occurring.
Whether you need to randomize a playlist, create random team assignments, shuffle flashcards for studying, or determine a random order for any purpose, this tool provides a fair and unbiased result.
Features
Multiple Separators
Support for various list formats including new lines, commas, semicolons, tabs, spaces, or any custom separator you need.
Data Cleaning Options
Automatically trim whitespace, remove empty items, and optionally remove duplicates before shuffling.
Undo History
Made a shuffle you want to reverse? Use the undo feature to go back to previous results (up to 10 history entries).
Use as Input
Quickly use your shuffled result as the new input to continue shuffling or make modifications.
Frequently Asked Questions
Is the shuffle truly random?
Yes! We use the Fisher-Yates shuffle algorithm, which mathematically guarantees that every possible permutation has an equal probability of occurring. This is the most reliable shuffling method available.
What's the maximum list size I can shuffle?
There's no strict limit, but for best performance we recommend lists under 10,000 items. The tool runs entirely in your browser, so very large lists may cause slower performance.
Is my data secure?
Absolutely. All processing happens locally in your browser. Your list data is never sent to any server or stored anywhere. Once you close the page, your data is gone.
Can I shuffle the same list multiple times?
Yes! Just click the "Shuffle List" button again to get a new random order. You can also use the "Use as Input" button to take your shuffled result and shuffle it again.
