Marshmallow (the server)

Marshmallow is a Python library that helps developers organize and manage data serialization in web applications. It allows you to convert complex data types, like objects or database records, into formats suitable for transfer over the internet, such as JSON. Marshmallow also validates incoming data to ensure it meets specified criteria before processing. Think of it as a translator and validator that streamlines the process of sending structured data between different parts of an application or between systems, making data handling more reliable and efficient.
