JSON to Go Struct Generator
Convert JSON data to Go struct definitions with JSON tags. Generate idiomatic Go code with proper field names and types.
Generated Go struct will appear here...
Field names are converted to PascalCase following Go conventions. Nested objects become separate structs unless inline mode is enabled.
Why Use JSON to Go Struct?
When working with JSON APIs in Go, you need to define struct types to marshal and unmarshal data. This tool automatically generates idiomatic Go structs from JSON samples, including proper JSON struct tags and type inference, saving you time and reducing errors.
Frequently Asked Questions
What are JSON struct tags?
JSON struct tags in Go tell the encoding/json package how to map struct fields to JSON keys. They're essential for proper serialization when field names differ between Go (PascalCase) and JSON (camelCase or snake_case).
When should I use omitempty?
Use omitempty when you want to exclude zero-value fields from JSON output. This is useful for optional fields that shouldn't appear in the JSON when not set.
Should I inline nested structs?
Inline structs are useful for simple, one-off nested objects. For reusable types or complex structures, separate struct definitions are cleaner and more maintainable.
