List Randomizer
Shuffle your lists and pick random items.
Enter the values and review the result.
Enter one item per line. Comma-separated lists also work when pasted as a single line.
Calculation assumptions
- *The list is shuffled with browser pseudo-random behavior.
- *Duplicate entries stay duplicated unless you remove them before shuffling.
- *Use this for simple random ordering, not audited contests, legal drawings, or regulated lotteries.
Enter your values and press Randomize List.

How list randomizing works
Paste items one per line, or paste a comma-separated list on one line. The tool trims blank spaces, removes empty lines, and shuffles the remaining items into a new order.
Example: enter Alice, Bob, Charlie, and Dana to create a random presentation order or chore order.
Assumptions and common mistakes
Duplicate items are kept as separate entries. If the same name appears twice, it can appear twice in the randomized output.
- Enter at least two items; one item cannot be meaningfully shuffled.
- Remove duplicates first if each person or option should appear only once.
- Use one item per line for best readability.
- Do not use this for audited contests, legal drawings, or regulated lotteries.

Accuracy and limitations
Calzivo tools are built for practical estimates, conversions, and checks. Some tools use standard formulas or simplified assumptions, and results can be affected by input accuracy, rounding, units, local rules, or changing official requirements.
Results depend on the values you enter and any simplified assumptions used by the tool. Verify important results before making decisions or submitting official information.

Frequently Asked Questions
Common questions about List Randomizer and how to read the result.

Are duplicate items removed?
No. Duplicate items stay in the list unless you remove them before shuffling.
Can I shuffle just one item?
