Fisher-Yates algorithm
Randomize in one click
Data never leaves your browser
Paste your list above to sort, clean, and transform. All processing happens in your browser — your data never leaves your device.
Proper randomization for any list, using algorithms that ensure every possible order is equally likely.
Randomize your entire list instantly with a single click. No configuration needed - just paste and shuffle.
Fisher-Yates algorithm ensures every possible ordering has equal probability. Truly fair randomization.
Don't like the result? Shuffle again for a completely new random order. Each shuffle is independent.
Use shuffling to pick random winners or samples. The first N items after shuffle are your random picks.
Works with lists of any size - from a few items to thousands. Browser-based processing handles it all.
All randomization happens in your browser. Your list is never uploaded or stored anywhere.
Randomize all items in your list. Every item moves to a random new position for complete reordering.
Need to select one random item? Shuffle and take the first item for an unbiased random selection.
Select N random items without replacement. Shuffle and take the first N items from the result.
Click shuffle again for an entirely new random order. Previous results don't affect new shuffles.
Pick random students to answer questions, form groups, or determine presentation order fairly.
Randomize the order of presenters, topics, or agenda items for meetings and conferences.
Shuffle question order to reduce bias in surveys, tests, and questionnaires.
Select random winners from a list of participants for contests, raffles, and promotions.
Divide a group into random teams by shuffling names and splitting into equal groups.
Randomize song lists, reading lists, or any sequential content for variety.
Create fair seating charts by randomly assigning seats to attendees or students.
When multiple options are equally valid, randomize to make fair, unbiased choices.
ListWrangler uses pseudo-random number generation (PRNG), which means the random numbers come from a deterministic algorithm rather than physical randomness (like atmospheric noise or radioactive decay). For most practical purposes, this distinction doesn't matter.
Modern PRNGs, including JavaScript's Math.random() that we use, produce results that are statistically indistinguishable from true randomness for applications like shuffling lists, picking winners, or creating random groups. The Fisher-Yates shuffle algorithm we implement ensures that every possible ordering has exactly equal probability.
For cryptographic applications (like generating passwords or encryption keys), you would need a cryptographically secure random number generator. But for classroom activities, giveaways, and general randomization, ListWrangler's shuffle is more than fair and random enough.
ListWrangler uses JavaScript's Math.random() combined with the Fisher-Yates shuffle algorithm, which produces a uniform random distribution. Every possible ordering has an equal probability of occurring. While it's pseudo-random (not cryptographically secure), it's more than sufficient for classroom activities, giveaways, and general randomization needs.
Yes! After shuffling your list, you can take the first N items as your random selection. For example, shuffle a list of 30 students and take the top 5 for a random group. Each shuffle produces a new random order, giving you a fair selection every time.
It's pseudo-random, which means it's generated by an algorithm rather than true physical randomness. However, modern pseudo-random number generators are excellent for practical purposes like random selection, shuffling game cards, or creating fair orderings. For cryptographic purposes, you'd need a different tool.
Absolutely! Click the shuffle button again to get a completely new random order. Each shuffle is independent - the previous order doesn't affect the next one. You can shuffle as many times as you like until you're satisfied with the result.
Mathematically, yes, it's possible but extremely unlikely for lists of any reasonable size. A 10-item list has over 3.6 million possible orderings. A 20-item list has over 2 quintillion possibilities. The chance of getting the exact same order twice is astronomically small.
Yes, shuffling is a fair way to select random winners. For complete transparency in public contests, you might want to record the shuffle on video or use a dedicated lottery tool. But for classroom activities, team assignments, and informal giveaways, ListWrangler's shuffle is perfectly fair.
