About Randomize Numbers
The Randomize Numbers tool lets you shuffle and reorder a set of numbers instantly. Whether you need to randomize a list of numbers for a raffle, create random test data, shuffle quiz answers, or generate random sequences, this tool provides fast and reliable results with multiple output formats and handy options.
Two Powerful Modes
Shuffle Mode
Paste or type your numbers, and the tool will randomly reorder them using the Fisher-Yates shuffle algorithm. This mode is ideal for:
- Randomizing the order of existing numbers
- Shuffling raffle tickets or lottery draws
- Creating random question orders for quizzes
- Reordering data for randomized experiments
Generate Mode
Specify a range (minimum and maximum) and how many numbers you need. The tool generates random numbers for you. Options include allowing or preventing duplicates.

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.
