JSON to Go Struct Generator

Generate Go structs with JSON tags from any JSON object.

JSON Input

Go Struct Output

type Root struct {
	UserName string `json:"user_name"`
	Age int64 `json:"age"`
	Email *string `json:"email"`
	Scores []int64 `json:"scores"`
	Address Address `json:"address"`

Go uses struct types with field tags for JSON serialization. The encoding/json package reads the json:"..." struct tags to map between JSON keys and Go field names. This generator converts JSON keys to PascalCase Go field names while preserving the original JSON key names in the struct tags, following Go conventions.
