How to use Create Random Integers
- 1. Set how many numbers to generate. Enter How many numbers to control the size of the generated list, whether you need a handful of values or a large batch.
- 2. Set the value range and separator. Enter Minimum value and Maximum value to bound the random integers, and choose a Separator to control how the values are joined in the output, such as a comma and space.
- 3. Generate and copy the list. Click generate to produce a fresh set of random integers, then copy the result into your test data, spreadsheet, or wherever sample numbers are needed.
When to use Create Random Integers
Create Random Integers generates a list of random whole numbers within a range you choose, useful whenever you need sample data quickly without writing a script. Adjust the count, range and separator to match exactly what you need.
- Populating a spreadsheet with test data. A spreadsheet template needs realistic-looking sample numbers, like five values from 1 to 100, to demonstrate a formula or chart before real data is available.
- Rolling dice or picking random values for a game. A tabletop game session or app prototype needs a quick way to generate random dice-like rolls or lottery-style picks within a defined range.
- Seeding a database or test fixture. A test suite needs a batch of random integers to populate a column for load testing or to exercise edge cases in a query.
- Picking a random winner or sample from a range. A giveaway or raffle needs a random number picked from a range of ticket numbers, generated on the spot without opening a separate script or app.
Examples
Five random integers from 1 to 100
Output
42, 7, 89, 3, 56
Three dice rolls (1 to 6)
Output
4, 1, 6
About the Create Random Integers tool
Create Random Integers runs as plain JavaScript in your browser tab, with no server behind it. Generate a list of random integers. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Integer Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
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.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Create Random Integers free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
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.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
