Go's strict typing requires struct definitions for JSON parsing. Our generator creates idiomatic Go structs with proper json tags from your API response data.

Example Generation

Input JSON:

{
  "user_id": 123,
  "full_name": "John Doe",
  "is_admin": false,
  "tags": ["developer", "admin"]
}

Generated Go:

type Root struct {
    UserID   int      `json:"user_id"`
    FullName string   `json:"full_name"`
    IsAdmin  bool     `json:"is_admin"`
    Tags     []string `json:"tags"`
}

Key Features

PascalCase: Field names converted to Go conventions
JSON Tags: Original JSON keys preserved in tags
Type Inference: Correct Go types for all JSON values
Nested Structs: Complex objects become separate types

Using Generated Structs

package main

import (
    "encoding/json"
    "fmt"
)

func main() {
    jsonData := `{"user_id": 123, "full_name": "John"}`
    
    var user Root
    json.Unmarshal([]byte(jsonData), &user)
    
    fmt.Println(user.FullName) // "John"
}

Type Mappings

JSON strings → string
JSON integers → int
JSON floats → float64
JSON booleans → bool
JSON arrays → []Type
JSON objects → Nested structs
