How does the randomizer shuffle a list?
It uses the Fisher-Yates shuffle, which iterates from the last item to the first and swaps each one with a randomly chosen earlier item. This algorithm produces a uniform distribution over all permutations, meaning every possible order is equally likely. Naive sort-by-random methods are biased and should not be trusted for fairness-sensitive applications.
Is the randomness truly random?
It uses the browser's built-in pseudo-random number generator, which is seeded from system entropy and is good enough for games, picking winners, and casual ordering. It is not cryptographically secure, so do not rely on it for high-stakes draws like lotteries or legally binding raffles. For those cases use a verifiable random source backed by a server with audit logs.
Can I shuffle a list without losing duplicates?
Yes - duplicates remain in the output exactly as many times as they appeared in the input. The shuffler does not deduplicate. If you want unique items only, run the duplicate remover first, then shuffle. Keeping duplicates is useful for randomizing tasks where some items legitimately appear more than once, like a quiz with repeated practice questions.
How large a list can I shuffle?
The Fisher-Yates algorithm runs in linear time, so tens of thousands of items shuffle instantly in the browser. Memory is the main constraint - extremely long lists with thousands of characters per line eventually exceed what a tab can hold. For most use cases like shuffling names, tasks, or trivia questions you will not approach any limit.
Does the tool keep blank lines?
By default blank lines are kept and treated as items, so they end up randomly distributed in the output. If you want them stripped first, run the multiple whitespace remover or filter empty lines before shuffling. Keeping blanks is occasionally useful when you want random spacing in a list of poetry stanzas or questions with intentional gaps.
When is randomizing a list useful?
Pick a winner from a list of contest entries, randomize the order of survey questions to avoid bias, shuffle a playlist by hand when your music app does not, mix flashcards for studying, randomize player order in a game, or anonymize a sample by breaking the original sort order before sharing it. The list is endless.
