🔬Mini Tutorial

JSON to Go Struct Conversion PrincipleThis tool uses advanced JSON parsing algorithms to analyze JSON structure and generate corresponding Go struct definitions. It handles nested objects, arrays, and complex data types, automatically inferring appropriate Go types. The converter supports JSON struct tags, omitempty tags, and provides clean, formatted Go code that follows Go best practices and conventions.

Type Inference and MappingThe converter automatically analyzes JSON data structures and maps JSON types to corresponding Go types. Strings are mapped to string, numbers to int or float64, booleans to bool, and arrays to slice types.

Nested Structure HandlingFor nested JSON objects, the converter generates corresponding Go struct definitions and automatically handles reference relationships between structs. It supports complex nested hierarchies and array structures.

JSON Tags and MetadataThe converter supports adding JSON struct tags, including field mapping and omitempty options. These tags ensure that Go structs can be correctly serialized and deserialized with JSON data.
