Generate an Integer Vector

The Generate an Integer Vector tool lets you quickly create a list of integers based on a start, end, and step value. Whether you’re building arrays for testing, feeding a model, or generating values for calculations, this tool gives you total control over how your vector looks with real-time preview and formatting options.

You can paste or import input, choose between CSV, JSON, or line-by-line output, and even maximize the output view for working with long vectors. It’s clean, fast, and works entirely in your browser no setup, no server roundtrips.

Paste your input above or import a file below.

How to Use:

  • Paste values like this into the Input Range box: Start: 1 End: 100 Step: 5
  • Or import a file with that structure
  • Choose your Output format:
    • One per line
    • CSV (comma-separated)
    • JSON array
  • Toggle Maximize output if you need more space
  • Click Generate to update the result (or it updates live as you type)
  • Use Copy Output or Export to File to grab your vector
  • Hit Clear All to reset the tool completely

What Generate an Integer Vector can do:

  • Build a numeric vector using just Start, End, and Step
  • Support both ascending and descending sequences
  • Format the output for scripts (CSV), data structures (JSON), or reading (lines)
  • Work entirely client-side all updates happen as you type
  • Copy and export the final output in one click
  • File import support with real-time parsing
  • Live count of how many integers were generated

Example:

Input:

Start: 10
End: 0
Step: 2

Output (One per line):

10
8
6
4
2
0

Common Use Cases:

This tool is ideal for anyone working with datasets, automating tests, generating stubs, or needing fast, clean number sequences. You can skip scripts or spreadsheets just enter your range and step, and the vector is ready to use, however you need it.

Useful Tools & Suggestions:

After using Generate an Integer Vector, try Create an Integer Array if you want a more structured format with rows and columns. Or go with Generate Integer Triples to build grouped sets from that vector data.
