The Change Integer Sign tool flips the sign of every number in your list. Whether you’re working with positives, negatives, or zeroes, it quickly reverses the sign of each integer with live updates and smart filters. Use it to clean up data, prep for formulas, or just invert a set of values in seconds all right in your browser.
How to Use:
- Paste your list of integers into the left box, one per line or separated by spaces.
- Or import a file using the Choose File button.
- Below the input box, you’ll find:
- Ignore non-integers (toggle): skips anything that isn’t a valid integer.
- Remove duplicates (toggle): keeps only one of each output after flipping.
- Maximize output (toggle): makes the output box larger for long lists.
- The output updates instantly as you type or adjust toggles.
- Use Copy Output to copy results, or Export to File to save them.
- Hit Clear All to reset everything.
What Change Integer Sign can do:
This tool instantly changes the sign of every integer you give it. It flips negative numbers to positive, and positive numbers to negative while zero stays unchanged. You can clean input by ignoring invalid entries and even remove duplicate results. It’s super lightweight, runs entirely in your browser, and works great with imported .txt or .csv files too.
Example:
Input:
15
-42
banana

0Common Use Cases:
Perfect for data cleanup, test data inversion, or prepping lists for subtraction or mirroring tasks. You might use this when you want to reflect values across zero, flip financial gains to losses, or standardize list formats before using them elsewhere.
Useful Tools & Suggestions:
After using Change Integer Sign, try Take Absolute Value of Integers if you want to strip away all signs completely. And if you’re preparing data for that change, Filter Integers can help you isolate just the positives or negatives first.
