How to use Generate Random Points
- 1. Set dimensions and range. Enter Dimensions to choose how many coordinate values each point has, then set Minimum value and Maximum value to bound what each coordinate can be.
- 2. Set precision and quantity. Enter Decimal places to control coordinate precision and How many points to set the batch size, then choose a Separator for how points are joined.
- 3. Copy the generated points. Copy the coordinate list and paste it into a plotting script, a test dataset for a clustering algorithm, or anywhere n-dimensional sample points are needed.
When to use Generate Random Points
Generate Random Points produces n-dimensional coordinate tuples within a range you set, useful whenever an algorithm or visualization needs sample point data at any dimensionality, not just 2D or 3D.
- Testing a clustering algorithm. You are implementing k-means or a similar clustering method and want a batch of random points at a chosen dimensionality to confirm the algorithm converges on synthetic data.
- Populating a scatter plot demo. You are building a charting library example and need sample 2D points scattered within a set range to show off how the plot renders and scales axes.
- Fuzz testing a distance function. You wrote a Euclidean distance function meant to work at any dimension count, and want generated points at varying Dimensions values to confirm it handles each case.
- Generating sample input for a machine learning demo. A tutorial on nearest-neighbor search needs quick sample data points at a specific dimensionality and decimal precision to plug into the example code.

About the Generate Random Points tool
Generate Random Points runs as plain JavaScript in your browser tab, with no server behind it. Generate random n-dimensional points. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Random Tools section, 120 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 6 settings, including Dimensions, Minimum value, Maximum value and Decimal places, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
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
Does Generate Random Points cost anything?
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?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
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?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
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.
