Rotate a Number

Rotate a Number lets you shift each number’s digits by a custom amount. You control how many digits to rotate and in which direction. Whether you’re scrambling input, testing logic, or formatting data, this tool gives you live control over the output.

What Rotate a Number can do:

The tool shifts the digits of each number line by the amount you choose. For example, rotating 123456 by 2 digits to the right becomes 561234. Rotating left would give you 345612. It works line-by-line and ignores empty input.

You can process bulk numbers easily with live feedback and a counter showing how many lines were handled.

Example:

Input:

123456
908172

Settings: Rotate by: 2, Rotate right: ON, Trim whitespace: ON

Output:

561234
729081

Common Use Cases:

Use this tool to create scrambled IDs, simulate number shifts in logic problems, or prep numeric data with cyclic transformations. It’s ideal for developers, educators, and anyone needing to rotate numbers without formulas or scripts.

Useful Tools & Suggestions:

If you’re rotating digits, Reverse a List is a great sidekick it flips the order completely instead of cycling it. And when you want to take those reordered numbers and format them visually, Change Number Font gives them a bold or stylized twist.
