Create an Integer ZigZag

The Create an Integer ZigZag tool lets you generate a wave-like integer pattern that climbs up, reverses, and climbs again repeating this zigzag cycle however many times you want. Just set a range using Start, End, and Step, then define the width (how many full up/down cycles), and you’ll get a smooth, repeating sequence like 1 2 3 2 1 2 3 2 1.

You can customize the output to be one number per line, a CSV, or a JSON array. It updates live as you type and supports full import/export features, so it’s flexible enough for developers, students, and data folks alike.

How to Use:

  • In the Input Pattern box, enter at least: Start: 1 End: 5 Step: 1 Width: 3
  • Or import a .txt or .csv file with similar lines
  • Use the Output format toggles to choose:
    • One per line
    • CSV
    • JSON array
  • Use Maximize output if you’re generating a long pattern
  • The output updates automatically, with a flash to show changes
  • Click Copy Output to copy it to your clipboard
  • Use Export to File to save the pattern
  • Click Clear All to reset everything

What Create an Integer ZigZag can do:

  • Generate smooth zigzag number patterns across any custom range
  • Repeat the up-and-down cycle as many times as needed using Width
  • Choose output style: line-by-line, CSV, or JSON
  • Copy or export results in one click
  • Import input from safe plain-text files
  • Display the total number of integers generated
  • Work completely client-side for speed and safety

Example:

Input:

Start: 1
End: 3
Step: 1
Width: 2

Output (One per line):

1
2
3
2
1
2

1

Common Use Cases:

Need a loop-like number pattern for a game, animation cycle, or mock data? This tool makes that quick and easy. It’s also great for teaching sequences, generating wave signals, or just experimenting with numeric patterns no programming required.

Useful Tools & Suggestions:

If you’re experimenting with Create an Integer ZigZag, try Generate Oscillating Integers to play with a back-and-forth number flow. And if you want to line things up nicely, Center Integers helps keep the pattern visually clean.
