Clamp Integer Digits

Clamp Integer Digits is a tool that lets you restrict each digit in a list of integers to stay within a defined range. For example, you can clamp all digits to fall between 1 and 7 any digit outside that range gets snapped to the nearest boundary. It’s a fast way to reduce digit variance, shape patterns, or clean up a list without changing the overall structure.

You can preserve negative signs, optionally clamp those too, and even strip out non-digit characters entirely. The output updates as you type or change options. And like all tools here, it runs 100% in your browser. Nothing leaves your device.

Paste your input above or import a file below.

Supported file types: .txt, .csv, .tsv, .log, .json, .xml, .md, .ini, .yaml, .yml, .html, .htm, .css

How to Use:

  • Paste or type numbers into the Input Integers box.
  • Or use the Choose File button to import a file (.txt, .csv, etc.).
  • Set the Min Digit and Max Digit (must be between 0–9).
  • Use the toggles:
    • Preserve sign: Keeps negative signs intact.
    • Clamp negative digits: Applies clamping to numbers starting with -.
    • Remove non-digits: Strips out characters that aren’t numeric.
    • Maximize output: Expands the output box for better visibility.
  • The output updates live with every change or keypress.
  • Use Copy Output to grab the results.
  • Use Export to File to save them.
  • Hit Clear All to reset everything, including file and toggles.

What Clamp Integer Digits can do:

  • Force every digit in a number to stay within a min–max range.
  • Optionally preserve negative signs while clamping.
  • Remove non-digit noise like letters, spaces, or symbols.
  • Clamp inputs from files just as easily as pasted text.
  • Preview results instantly as you type or toggle.
  • Keep everything fast and secure runs fully in your browser.
  • Show character count below the output window.
  • Copy or export the results with a single click.

Example:

Input:

5198
2043
-7931

Min Digit: 1 Max Digit: 7

Output:

5177
2143
-7731

Common Use Cases:

Clamp Integer Digits is perfect when you want to sanitize data, enforce digit bounds, or make numeric patterns more predictable. It’s great for testing algorithms, compressing values, or visually standardizing datasets. Whether you’re processing real data or experimenting, it’s a handy utility to keep around.

Useful Tools & Suggestions:

Once you’ve used Clamp Integer Digits, try Decrement Integer Digits or Increment Integer Digits to nudge values before clamping them. If you’re cleaning up messy inputs, Separate Integer Digits is a good way to check what’s getting clipped.
