Everything you need to know about using this tool effectively

What is List Randomizer?

The List Randomizer shuffles items into a random order. You paste a list with one item per line, and the tool rearranges them using the Fisher-Yates algorithm. Each item has an equal probability of appearing in any position. You can optionally set a seed for reproducible results. All processing happens in the browser.

This tool takes a line-separated list and applies the Fisher-Yates shuffle to produce a uniformly random permutation. It treats each line as a separate item, so duplicate lines are shuffled as distinct entries. A seed option lets you reproduce the same shuffle order when needed.

Pro Tips
1

Each shuffle produces a different order unless you use the same seed.

2

Remove empty lines before shuffling to get a cleaner result.

3

For extra randomness, shuffle twice.

4

The seed option is useful when you need the same order on different devices.

Frequently Asked Questions
How random is the shuffle?

The tool uses the Fisher-Yates algorithm, which guarantees a uniform distribution. Every item has an equal chance of ending up in any position.

Can I reproduce the same shuffle?

Yes. Enter the same seed value and the tool produces the same order every time. This is useful for testing or when multiple parties need the same result.

What happens to duplicate items?

Each line is treated as a separate item. If you have duplicate lines, they appear multiple times in the shuffled output.

Is there a limit on list size?

There is no hard limit. The tool handles thousands of items, though very large lists may take a moment depending on your device.

Is my list uploaded to a server?

No. All processing happens in your browser using JavaScript. The list never leaves your device.
