UUIDs are commonly used in databases, APIs, and application development. But depending on the workflow, you may need the same UUID in different formats.
For example, you might need a standard UUID with hyphens, an uppercase representation, or a format without hyphens.
Instead of converting these manually, you can use an online tool.
Meet the UUID Formatter
The UUID Formatter by UUIDTools.online helps you format UUID values into different representations.
What can you do with it?
- Standard format: Keep the familiar hyphenated representation.
- Without hyphens: Get a compact representation.
- Uppercase and lowercase: Change letter casing as needed.
- URN format: Represent the UUID using the URN notation.
- Validation: Check UUID values.
- Quick copying: Copy formatted output for use in your workflow.
When is it useful?
A UUID formatter can be handy when preparing database test data, debugging API responses, working with logs, or matching an identifier format expected by an application.
It is a small utility, but it can save repetitive manual work during everyday development.
