How to use Generate Random Numbers
- 1. Set how many numbers. Enter How many numbers to decide the length of the list, from a handful for a quick dice roll simulation to hundreds for a sample dataset.
- 2. Set the value range. Enter Minimum value and Maximum value to bound the random numbers, matching whatever range your use case calls for, from a 1 to 6 die to a 1 to 100 raffle range.
- 3. Choose a separator and copy. Set Separator to a comma or newline, then copy the random numbers into your worksheet, script or randomized test data.
When to use Generate Random Numbers
Generate Random Numbers produces a list of random integers within a range you choose, all in your browser without a server round trip. Use it whenever a game, a lesson or a piece of test data needs unpredictable numbers without rolling dice or flipping coins by hand.
- Simulating dice rolls or raffle draws. Someone running a board game night or raffle without physical dice sets the range to 1 through 6, or 1 through however many entries there are, and generates the needed rolls or draws.
- Seeding test data for a script. A developer testing how a script handles arbitrary numeric input generates a batch of random numbers within an expected range to feed through the function during development.
- Picking a random sample for a lesson. A teacher wanting to call on students in random order, or assign random values for a probability exercise, generates a quick list instead of drawing names from a hat.
- Creating placeholder values for a mockup. Someone building a chart or dashboard mockup that needs sample numeric data pastes a batch of random numbers instead of manually typing plausible-looking values.
Examples
Five random numbers from 1 to 100
Output
42, 7, 89, 3, 56
Three dice rolls (1 to 6)
Output
4, 1, 6
About the Generate Random Numbers tool
Generate Random Numbers is a free online tool that works entirely inside your web browser. Quickly generate random numbers. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 234 Math utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 4 settings, including How many numbers, Minimum value, Maximum value and Separator, and the result refreshes the moment you change one. 2 worked examples further down the page show exactly what the tool produces for real inputs.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.

How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
