Frequently asked questions

Is the shuffle truly random?

Yes. We use the browser's crypto.getRandomValues API, which provides cryptographically secure random numbers suitable for lotteries, raffles, and scientific sampling.

Can I shuffle comma-separated values?

Absolutely. Choose Comma as the delimiter and the tool will treat each CSV field as a separate item.

Does removing duplicates preserve order?

Deduplication happens before shuffling, so the first occurrence of each item is kept. The final order is then randomized.

Is there a limit to list size?

The tool runs entirely in your browser and can comfortably handle lists with tens of thousands of items.
