Generate an Integer Sequence

Generate an Integer Sequence gives you a fast way to list out numbers between two points. Just type a range like 1 to 10 or 20-5, and it’ll fill in every number in that span forward or backward. The sequence appears instantly, one number per line.

You can use it to make test data, number lines, iteration sets, or just when you need a clean list without typing it all out yourself. Once the sequence shows up, you can copy it with a click or download it as a .txt file.

Paste your input above or import a file below.

How to Use:

  1. Type a range using “to” or a dash. For example: 1 to 10 10-1
  2. Click “Generate” or just type the sequence appears live.
  3. View the full number list in the output box.
  4. Click “Copy Output” to copy to clipboard.
  5. Click “Export to File” to download the sequence as text.
  6. Click “Clear All” to start over.

Example:

Input:

3 to 7

Output:

3  
4  
5  
6  
7

It works the same in reverse too. Just enter 10 to 6.

Common Use Cases:

Generate an Integer Sequence is great for developers needing number input, teachers making worksheets, or anyone doing quick data work. It’s also useful for spreadsheet tasks, loop testing, and creating sample datasets. You type the range the tool does the work. No formulas, no scripts, just numbers.

Useful Tools & Suggestions:

If you’re working with integer sequences, Slice a List helps you pull out just the part you want to focus on. And for a more visual spin, Create a Number Spiral turns that sequence into something you can actually see take shape.
