Developer Toolbox: JSON, UUIDs, and JWTs Explained

3/6/20261 min readDeveloper tools, APIs, Debugging

How to use common developer tools like JSON formatters, UUID generators, and JWT decoders.

If you build or debug APIs, you will use JSON, UUIDs, and JWTs daily. These tools save time and reduce mistakes.

JSON Formatter

Unformatted JSON is hard to read and easy to break. A formatter validates and pretty-prints the data.

UUID Generator

UUIDs are unique identifiers. You often need them for test data, mock records, or API requests.

JWT Decoder

JWTs are encoded. A decoder helps you verify payloads, expiry, and claims without copying into scripts.
