Increment Integer Digits

Increment Integer Digits is a fast browser tool that increases each digit of every number you enter turning 123 into 234, or 908 into 019. You can choose whether 9 wraps to 0 or stays capped, and it works with negative numbers too. The tool handles files, filters duplicates, and shows live results as you type. Changes happen live, so you always know what your final result will look like.

Paste your input above or import a file below.
No file chosen
Supported file types: .txt, .csv, .json, .log, .md, .html, .htm
Total items: 0
Options
Wrap 9 to 0
Ignore non-integers
Remove duplicates
Maximize output

How to Use:

  • Paste integers into the input box one number per line
  • Or use Choose File to import from .txt, .csv, .json, etc.
  • Use the Options toggles to customize:
    • Wrap 9 to 0 – makes 9 → 0 instead of staying at 9
    • Ignore non-integers – skips invalid input lines
    • Remove duplicates – prevents repeat outputs
    • Maximize output – expands the result view area
  • Results update instantly when you type or toggle anything
  • Click Convert to re-process your input
  • Use Copy Output to copy results
  • Use Export to File to save the output as a .txt
  • Hit Clear All to reset input, output, and toggles

What Increment Integer Digits can do:

Need to mutate digits for obfuscation, generate shifted number series, or teach number manipulation? Increment Integer Digits gives you complete control over how each digit transforms. It works line-by-line, handles signs properly, and respects your choice to wrap digits or not.

Because you can import and export data, it’s ideal for batch tasks or data preprocessing. Great for math educators, programmers testing input patterns, or anyone working with numeric strings.

Example:

Input:

123
908
-321
440

Output (with wrap on):

234
019
-432
551

Output (with wrap off):

234
919
-432
551

Common Use Cases:

Use this when creating transformed number sets for practice drills, pseudorandom values, or simply exploring how digits shift across inputs. Because it preserves formatting and supports toggles for cleanup and export, it’s great for anyone working with numbers in bulk educators, testers, devs, or data nerds.

Useful Tools & Suggestions:

After using Increment Integer Digits, try Decrement Integer Digits to reverse the effect and compare outcomes. And if you’re making lots of changes, Clamp Integer Digits can help keep the results within valid digit limits.
