List Randomizer

Shuffle any list into random order

Paste one item per line and generate a randomized order for names, teams, tasks, songs, presentation slots, classroom turns, seating lists, or test cases.

• Empty rows are ignored and leading or trailing spaces are trimmed.
• Copy the output with or without numbering.
• Download TXT or CSV results.
• Use a seed to reproduce the same order for the same list.
• Optionally avoid adjacent duplicate text or avoid keeping items in their original positions.

How the shuffle works

The standard shuffle uses the Fisher-Yates algorithm: it walks backward through the list, chooses a random index from the remaining range, and swaps the two items.

If no seed is provided, the browser Math.random source is used. It is suitable for casual list shuffling, not cryptographic or audited draws.

Fairness limits

For prizes, money, regulated contests, gambling, or legally meaningful selection, use a process designed for those requirements.
