JSON schema allows checking the validity of JSON objects against a manually specified schema. It can power autocompletion and hover annotations for a wide range of text editors and IDEs.

The JSON Schema Store provides a repository of many pre-made schemas.

The website provides the documentation about the standard.

There are also a couple of websites which provide online editors for those schemas.

These websites provide tools, which convert JSON data to structs in different programming languages.
