Randomize List - Shuffle List Items Randomly Online

What Is a List Randomizer?

A List Randomizer is a free online tool that shuffles the order of items in a list randomly. Whether you have a list of names, numbers, tasks, or any text entries, this tool uses the Fisher-Yates shuffle algorithm to produce a truly randomized order. You can customize how items are separated in both input and output, making it flexible for any formatting need.

How to Use the List Randomizer

Enter your list — Paste or type your items into the input textarea, one per line or separated by your chosen delimiter.
Configure separators — Set the input separator (how your items are currently divided) and the output separator (how you want them joined after shuffling). Use \n for newline, \t for tab, or any custom character. Switch to Regex mode for advanced splitting.
Adjust options — Toggle "Preserve empty lines" to keep blank entries, or "Trim whitespace" to strip surrounding spaces from each item.
Get your randomized list — The output updates instantly. Copy the result to your clipboard or download it as a text file.

Frequently Asked Questions

Is the shuffle truly random?

Yes. This tool implements the Fisher-Yates (also known as Knuth) shuffle algorithm, which produces an unbiased permutation. Every possible ordering of your items is equally likely.

Can I shuffle by something other than newlines?

Absolutely. The default separator is \n (newline), but you can change it to any character, string, or even a regular expression (by toggling Regex mode). For example, use , to split by commas or \s+ to split by any whitespace.

Will the shuffle produce the same result twice?

No. Each time you change the input or click any option, the list is re-shuffled randomly. The output will almost certainly be different each time, giving you a fair random ordering every use.

What happens to empty lines in my list?

By default, empty lines are removed before shuffling. If you need to preserve blank entries (for example, to maintain position placeholders), uncheck "Preserve empty lines" and they will be kept and shuffled along with the rest.

Is there a limit to how many items I can shuffle?

There is no hard limit. The Fisher-Yates algorithm runs in O(n) time, so even lists with thousands of items are shuffled instantly in your browser.
