Generate Random Vectors

Need a quick list of random numbers? This tool makes it dead simple. Just say how many values you want like 50 or 500 and you’ll get a live vector right away. You can control the format (commas, spaces, or new lines), choose whether you want only whole numbers or decimals, and even fix the decimal length. Want negative values in the mix? Just toggle it on. It updates instantly, and you can copy or export it in one click.

How to Use:

  1. Type how many values you want into the input box (like 25).
  2. Choose your output format: comma, space, or one-per-line.
  3. Flip on any settings you need:
    • Allow decimals
    • Include negatives
    • Fixed decimal length

Example:

Input:

10

Settings:

  • Format: Space-separated

Output:

91.137 -20.57 8.9 -0.1 37.4 -6.78 92.3 -42.8 18.7 0.44

Common Use Cases:

Great for generating mock data, testing functions, or seeding simulations. You can go full precision with decimals or keep it clean with integers. The live formatting lets you preview exactly what you’ll use, whether you’re feeding it into a spreadsheet, script, or machine learning model. Just set your rules and go.

Useful Tools & Suggestions:

After generating random vectors, Flatten a List is helpful if you’re prepping the data for calculations or analysis elsewhere. And if you want to display or explore the structure visually, Visualize a List gives you a clear, easy-to-scan layout of the values.
