Increment Integers

Got a list of numbers you want to bump up by 1… or 10… or 0.5? The Increment Integers tool lets you do exactly that. Drop in your list, pick the separator, set how much to add, and it updates everything live. You can format the result, copy it, or download it all without refreshing the page.

How to Use:

  • Paste your list of numbers into the Input Text box
  • Set your Increment by value (defaults to 1)
  • Use the Input is options to tell the tool how your list is separated:
    • Comma-separated
    • Space-separated
    • One per line
    • Custom delimiter
  • Flip the Maximize output switch if you want more space to see results
  • Click Convert to apply the increment
  • Use Copy Output to copy your result
  • Click Export to File to save it as a .txt
  • Use Clear All to reset everything
  • You can also import a .txt or similar file to process the input

What Increment Integers can do:

This tool updates a batch of numbers in one shot no formulas, no code. You can apply any increment you want (including negatives), choose how the input is split up, and get a clean list of new values. If the input includes non-numbers, the tool leaves them as-is so you don’t lose formatting or notes. It’s quick, simple, and all client-side.

Example:

Input Text:
10, 20, 30

Increment by:
5

Output:
15, 25, 35

Common Use Cases:

It’s great for offsetting datasets, adjusting numeric sequences, creating shifted test inputs, or updating values without doing it all manually. Whether you’re working on a spreadsheet, editing logs, or prepping test cases, this tool saves time and lets you control the format.

Useful Tools & Suggestions:

Once you’ve used Increment Integers, try Decrement Integers to reverse the operation and compare shifts. And if you’re tracking changes over time, Find the Running Total is a solid way to keep tabs on how values evolve.
