JSON to Go — Generate Structs with json Tags Instantly

Unmarshaling JSON into Go requires a struct where every field has the right json:"field_name" tag. Paste your JSON here and get idiomatic Go code back: camelCase and snake_case keys are mapped to exported PascalCase struct fields, and every field gets the correct tag appended automatically.

Arrays become []T slices. Nested objects become their own named structs. Numbers are mapped to int64 or float64 based on whether the value contains a decimal. The output is ready to drop into your Go project and pass to json.Unmarshal().
