List Randomizer
Enter names or items one per line to shuffle them into a random order. Turn on group splitting to divide them evenly into several groups. Great for deciding order, splitting teams, and presentation order. All results are generated in your browser.
Enter items and press Shuffle to see the result.
How to use
- Enter names or items, one per line.
- Turn on group splitting if you want and set the number of groups.
- Press "Shuffle" to show the random order (or groups).
Frequently asked questions
How does group splitting work?
It shuffles the items randomly, then divides them as evenly as possible into the number of groups you specify. Handy for splitting teams or forming groups.
Is the result really random?
Yes. Each shuffle uses the browser's randomness with the Fisher-Yates method, and results are generated only in your browser and never sent to a server.
Practical example and verification criteria
List Randomizer: First define the draw population—such as a candidate list, numeric range, or number of dice—and check whitespace, duplicates, and whether minimum and maximum values are inclusive. Before running it, agree whether repeated winners are allowed, whether selected entries are removed, and when a redraw occurs so rules do not change to fit the result.
List Randomizer: For a quick check, start with A,B,C,D → 4 items as a small input whose result relationship you can verify directly. Confirm that the input summary, units, and options match your intent before applying the tool to real values or a copy of the source; this reduces setup mistakes.
List Randomizer: Record the input list and options, then verify that the result is among the candidates or within the range and that nothing is missing or duplicated. Different results under identical conditions are normal. Browser randomness is for casual choices; regulated prizes, lottery prediction, cryptographic keys, or auditable drawings require local-rule compliance and a validated purpose-built system.
List Randomizer · Work record: For real work, record the input conditions, selected options, and result together. Do not assume the same state will remain after a refresh or device change. Preserve important results separately using copy, download, a screenshot, or another method the page supports, then reopen them in the target environment.
List Randomizer · Error check: If an error or unexpected result appears, reduce the input, run again with default options, and then change one condition at a time. Recording error messages and boundary values helps distinguish format issues, unsupported cases, and browser resource limits, and prevents an empty result from being mistaken for success.
List Randomizer · Scope of use: Check the page guidance for browser processing versus server lookup, storage location, and supported scope. Use sensitive source material or secrets only when strictly necessary. High-impact work such as legal, financial, or medical decisions or changes to an operational system requires current authoritative information and a separate verification process.
