List Randomizer
A high-performance Online List Randomizer designed to shuffle names, lists, or any text-based data with zero bias. Simply paste your items—whether one per line or separated by a custom character—and let our algorithm reorder them instantly. Perfect for picking winners, creating random sequences, or unbiased sampling. All randomization happens locally in your browser for total privacy and speed. The shuffle uses the Fisher-Yates algorithm, which walks the list backward and swaps each item with a randomly chosen position among the items that have not been placed yet, so every possible ordering is equally likely. Blank lines are dropped before shuffling, and the output rejoins with the same separator you picked — newline, comma, semicolon, or your own — making it easy to paste the result into another tool.

Using List Randomizer
It's straightforward — here's how it works.
Paste your list into the input area.
Select your item separator (usually 'New Line').
Click 'Shuffle List' to randomize the order.
Re-shuffle as many times as needed to get a new sequence.
Copy the randomized list or download it as a text file.
Questions People Ask
Honest answers about how this works.
How many items can it handle?
The tool can comfortably handle thousands of items in a fraction of a second, since a shuffle only reorders an array already in memory. Extremely large lists in the hundreds of thousands still work but depend on your device; pasting them gradually or splitting the list keeps things responsive on a phone.
Is the shuffle permanent?
No. Clicking Shuffle again runs the algorithm on the same items and produces a fresh order, and you can do that as many times as you like without re-entering the list. The input text itself never changes, so the original sequence is always available to compare against.
Does my list get uploaded anywhere?
No. The text you paste is split and shuffled in your browser's memory, and the result stays in the output box until you copy it or download it as a text file. Nothing is sent to a server, stored, or logged, so name lists and internal data never leave the machine.
