List Randomizer

List Randomizer takes any list you have — names, tickets, tasks, options, playlists — and rearranges it into a genuinely unpredictable order, or draws a set of random winners from it. Everything happens inside your browser using the JavaScript engine already running on your device. When you click shuffle, the tool applies the Fisher-Yates algorithm, which walks through the list from the last item to the first and swaps each entry with a randomly chosen earlier one. That method is the standard way to guarantee every possible ordering is equally likely, so no item is quietly favored the way naive "sort by random number" tricks often are. The randomness comes from the browser's crypto.getRandomValues where available, falling back to Math.random, meaning results are different on every run and are never seeded to a predictable pattern.

Because the work is client-side, your list is never uploaded to a server. You can paste a spreadsheet column of 5,000 email addresses, disconnect from the internet, and the tool still runs — the data lives only in the tab until you close it. That matters for giveaways where participants trust you to be fair, for HR shortlists you would rather not send to a third party, and for anything containing personal names.

Real uses are everywhere: Instagram or YouTube creators drawing prize winners from comment exports, teachers randomizing who presents first, managers assigning on-call rotations without bias, D&D groups picking turn order, developers deciding code-review pairings, and researchers randomizing survey question order. The "pick winners" mode is handy when you only need 3 names out of 800 rather than a full reshuffle.

Practical tips: paste one item per line so entries with commas stay intact, remove blank lines before shuffling to avoid empty picks, and if you need a verifiable public draw, screen-record the shuffle so entrants can see it was live. Re-clicking shuffle always produces a fresh order, so decide on your first result rather than re-rolling until you like the outcome — that keeps the draw honest.
