Frequently Asked Questions

How does the Randomize Numbers tool work?

The tool uses the Fisher-Yates shuffle algorithm to randomly reorder your numbers. You can enter numbers separated by commas, spaces, or line breaks. The tool also supports generating random numbers from a specified range, sorting results, removing duplicates, and exporting in multiple formats.

Is the randomization truly random?

The tool uses Python's random module which implements the Mersenne Twister pseudo-random number generator, one of the most widely tested and reliable PRNGs available. It provides excellent randomness for general-purpose shuffling, simulations, and games.

What output formats are available?

Results can be displayed in five formats: one number per line, comma-separated, space-separated, CSV (download-ready), and JSON array. All formats support one-click copy to clipboard.

Can I generate random numbers without duplicates?

Yes. In Generate mode, numbers are unique by default. You can enable "Allow Duplicates" if you need repeated values. In Shuffle mode, you can enable "Remove Duplicates" to eliminate any repeated numbers from your input before shuffling.
