About Random Team Generator

Random Team Generator helps turn a class list, workshop roster, game night guest list, volunteer group, study circle, or meeting attendee list into balanced groups in a few seconds. Paste one name per line, or use commas when the names already come from a spreadsheet or email. Choose how many teams you need and press Generate teams. The tool first reads the non-empty entries, then randomizes the roster and places every entry into one team. If the number of people does not divide evenly, the largest team has only one more person than the smallest team. For example, seven people split into three teams becomes group sizes of three, two, and two. This is a partitioning tool: it creates several groups. It is not a list shuffler, which only changes the order of one list, and it is not a random name picker, which selects one winner.

Everything happens in the current browser. The roster is not posted to a server, saved to an account, or sent to an organizer. That is useful when a list contains classmates, colleagues, children, clients, club members, or any other names you would rather not upload to a third-party service. Randomness is generated with the browser's cryptographically secure random source at the moment you click the button. The page does not choose a team while it is loading, and it does not quietly reuse a previous result. Generate again when you want a fresh grouping.

Each non-empty comma-separated or line-separated entry is treated as one place in the roster. Leading and trailing spaces are removed, while repeated names are preserved as repeated entries. That makes it possible to give a deliberately repeated entry more chances in a casual activity, but it also means you should remove accidental duplicates before generating if every person must appear only once. Blank lines and extra commas are ignored so you can format a long list for readability. The requested number of teams must be a positive whole number and cannot be larger than the number of entered names. These checks prevent empty groups and make the result easy to use immediately.

A practical workflow is to decide the number of groups before sharing your screen, paste the roster, verify that the visible count makes sense, and generate the teams once for the room. Read each team aloud or copy the displayed names into a chat, document, whiteboard, or sign-up sheet. If attendance changes, edit the roster and generate a new set rather than trying to move people between old groups by hand. For a large event, keep the original list elsewhere so you can repeat the draw if a participant arrives late. The result is intentionally simple: it balances headcount, but it does not infer skills, friendship preferences, accessibility needs, conflicts, or demographic information.

Use a different planning method when groups must meet those real-world constraints. A random draw can be a transparent and fast starting point, but it cannot guarantee that every team has a facilitator, a specific skill mix, compatible schedules, equal experience, or a safe pairing. Review the result before assigning work that affects evaluation, pay, safety, legal obligations, or personal wellbeing. For ordinary games, icebreakers, study sessions, classroom practice, and informal workshops, balanced random groups often remove the awkwardness of choosing people manually. Keep the tool focused on that purpose: it distributes the names you provide once each, keeps team sizes close, and leaves human judgment in charge of any important final adjustments.

Methodology & sources

The tool trims and filters comma- or line-separated entries, performs an unbiased Fisher-Yates shuffle using browser cryptographic random values, randomizes which team labels receive any remainder, and slices the shuffled roster into non-empty groups whose sizes differ by at most one.

Frequently asked questions

Does this only shuffle my list?
No. It partitions the roster into the number of groups you choose. Use List Randomizer when you only need a new order.
Will every person appear once?
Yes. Every non-empty entry is assigned to exactly one team, and team sizes differ by at most one.
Are names uploaded or stored?
No. The roster and generated teams stay in your browser.
