Create an Integer Array

The Create an Integer Array tool builds a clean, customizable list of integers based on your start, end, and step values. Whether you’re generating test data, ranges for scripts, or just need a quick array, this tool makes it super easy and it runs entirely in your browser.

End:
Step:
Total items: 0
Options
Remove duplicates
Reverse order
Maximize output

How to Use:

  • Enter a Start, End, and Step value in the top input fields.
  • Use the Generate button or just start typing the output updates instantly.
  • Toggle options under the Options box:
    • Remove duplicates – filters repeated numbers from the final array.
    • Reverse order – outputs the array in reverse.
    • Maximize output – expands the output area for large lists.
  • Use Copy Output to copy the result, or Export to File to download it.
  • Hit Clear All to reset everything back to default.

What Create an Integer Array can do:

This tool builds a dynamic array of integers you set the range and step, and it handles the rest. It supports both increasing and decreasing sequences, so you can go from 1 to 100 or 50 down to -50 with whatever step value you need. The output is comma-separated and updates live.

Use the built-in options to filter duplicates (useful with custom data), flip the array, or maximize the view. You can instantly copy or export your result, and the tool keeps a live count of how many items are in your array.

Example:

Settings:

Start: 2
End: 10
Step: 2

Output:

2, 4, 6, 8, 10

Common Use Cases:

This is great for developers needing test arrays, data scientists prepping quick input, or anyone working with number sets. It’s also handy for learning loops or checking sequence logic. You don’t need to code anything just input the numbers and go.

Useful Tools & Suggestions:

If you’re building grids with Create an Integer Array, try Generate an Integer Matrix when you need multiple rows and columns instead of just a single dimension. And for tighter formatting, Center Integers can help align everything cleanly.
