About Randomize List
Randomize List is a free web tool for shuffling lists, drawing winners, and splitting people into teams, pairs or a running order. Every draw is computed in your browser from a seed shown next to the result, and the lists you paste are not uploaded to a server or kept anywhere except your own browser.

What it does
Randomize List takes a list you paste and gives it back shuffled, or picks winners from it, or splits it into teams, pairs or a running order. A separate page makes lists of random numbers, and a guide shows how to do the same inside Excel and Google Sheets.
How results are made
Each draw starts from a seed that your browser’s cryptographic generator picks, and the same list, settings and seed always give the same result. That is what lets a share link replay a draw for someone else. The full method, with its limits, is on how the draw works.
How the site is checked
Every build runs 18 automated checks before it can be published, among them text uniqueness and length, titles and descriptions, canonical addresses, internal links, the sitemap, structured data against the visible text, and the size of the scripts. An error stops the release.
The sample draws and tables on each page are computed during the build by the same code your browser runs, and that code is covered by unit tests; browser tests then run the tools themselves. Before a release a script opens every external source again and reports any that do not answer, which is why each one on how the draw works carries the date it was checked. Before a group of pages goes live, a sample of them is read in full and every number on it is recalculated separately, without the site’s code.
Who runs it
The site is run under the name Randomize List. It has no accounts, no sign-up and no fees. Questions and bug reports go to contact@randomizelist.com.
What it does not do
It does not upload your list, keep it on a server or show it to anyone you have not sent a link to. It does not claim certified randomness: a seed proves that a result can be reproduced, not that nobody drew twice.
