About this tool
The Random Number Generator produces one or more random integers or decimals within a range you define. Set a minimum, set a maximum, choose how many numbers you need, and get results instantly. It is useful for developers, teachers, designers, researchers, and anyone who needs unbiased numerical values without pulling out a spreadsheet or writing a script.
Reach for this tool when you need a quick lottery draw, random sample selection, test data, dice roll simulations, or any situation where human-picked numbers introduce bias. It saves the five minutes you would otherwise spend opening Excel or writing a one-off code snippet just to get a handful of values.
How to use it
- Enter your minimum value in the Min field, such as 1.
- Enter your maximum value in the Max field, such as 100.
- Set how many random numbers you want generated at once.
- Choose integer or decimal output depending on your use case.
- Click Generate to produce your results immediately.
- Copy the output directly or regenerate for a fresh set.
Pro tips
- Set min and max to the same value temporarily to sanity-check that your form inputs are wired correctly before running real tests.
- Generate a large batch at once and paste into a spreadsheet column to build randomized test datasets without writing any code.
FAQ
Are the numbers truly random?
The generator uses your browser's built-in cryptographic or pseudo-random functions, which are statistically random enough for most practical purposes. For cryptographic security requirements, consult a dedicated library instead.
Can I generate duplicate numbers in a batch?
By default duplicates are possible, mimicking a real random draw with replacement. If you need unique values only, check the no-duplicates option if available, or reduce your batch size relative to your range.
