Validobj is library that takes semistructured data (for example JSON and YAML configuration files) and converts it to more structured Python objects. It places the emphasis on:

• Good error messages (rather than avoiding extra work in the error handling code).
• Schema defined in terms of dataclasses and other high level objects such as enums, as well as a subset of the typing module.
• Simplicity of implementation (rather than full generality).

Validobj requires Python 3.7 and has no other dependencies.
