JSON to Go Struct
Convert JSON to Go struct definitions instantly. Paste JSON and get clean Go code with proper types and tags.
How does JSON to Go struct conversion work?
The tool parses your JSON data and automatically generates Go struct definitions with proper field types, PascalCase naming, and optional json tags. Nested objects become separate structs or inline definitions.
What Go types are used for JSON values?
Strings map to string, numbers to int64 or float64 (your choice), booleans to bool, null to interface{}, arrays to []Type, and objects to nested structs. Mixed arrays use []interface{}.
What are json tags in Go structs?
Json tags like `json:"fieldName"` tell Go how to map struct fields to JSON keys during marshaling/unmarshaling. Adding omitempty skips zero-value fields in the output.
What does "pointers for optional" mean?
When enabled, nullable fields (with null values in JSON) use pointer types like *string instead of string, allowing you to distinguish between zero values and missing/null values in Go.
