json2go
A Go package and CLI tool that generates accurate Go struct types from JSON input, ensuring proper marshaling/unmarshaling.
What is json2go?
json2go is a Go package and command-line tool that converts JSON data into accurate Go struct type definitions. It solves the problem of manually writing Go types for JSON APIs or documents by automatically generating types that guarantee proper marshaling and unmarshaling, even for complex nested structures with optional fields.
Go developers working with JSON APIs, document-oriented databases, or any system requiring reliable serialization/deserialization between JSON and Go structs.
Developers choose json2go because it produces correct, production-ready type definitions that handle edge cases like null values, optional fields, and mixed document structures—unlike simpler converters that often generate incomplete or incorrect code.
