Format & developer tools
Format and developer tools transform or inspect representations directly in the browser. They cover JSON, Base64, URL components, UUIDs, timestamps, text, color notations, and cryptographically generated constrained passwords.
Common uses
- Inspect or prepare a value while debugging an application.
- Perform a local text, format, identifier, or password-generation task without sending the input to an external service.
These tools operate on representations and identifiers. Unit converters change measurement units, and calculators evaluate numeric scenarios.
