The Decrement Integers tool subtracts 1 or any step you choose from each number in your list. It updates live in your browser and gives you clean, ready-to-use output. You can paste values, import a file, and tweak settings to ignore non-integers or remove duplicates.
How to Use:
- Paste or type one integer per line into the input box.
- Or use Choose File to import from a supported text file.
- Adjust the Step value to change how much is subtracted from each number.
- Use the toggles in the Options box:
- Ignore non-integers – skips invalid lines.
- Remove duplicates – filters repeated results after decrementing.
- Maximize output – enlarges the output area.
- Output updates live as you type or adjust settings.
- Click Copy Output to copy results.
- Click Export to File to download the decremented list.
- Hit Clear All to reset everything instantly.
What Decrement Integers can do:
This tool takes each number you give it and subtracts a fixed amount (default is 1). So 10 becomes 9, or 42 becomes 40 if your step is set to 2. It handles full lists, updates live, and can clean up duplicates and non-numeric input on the fly.
It’s great for counting logic, reversing increments, or transforming datasets in bulk all in your browser, no setup needed.
Example:
Input:
10
banana
5
3
5Step:
1Output (with ignore + dedupe on):
9
4
2Common Use Cases:
Use this to reverse offset values, step back through sequences, or prep data for loops, flags, or test logic. It’s ideal for developers, students, or anyone working with structured number lists who wants fast in-browser results.
Useful Tools & Suggestions:
After running Decrement Integers, try Increment Integers to flip the change and compare results. And if you’re testing bounds, Clamp Integers can help keep values within your desired range.
