JSON to Go Converter

Why Convert JSON to Go Structs?

Proper JSON Tags

Automatically generates correct `json:"field"` struct tags for seamless marshaling and unmarshaling.

Type Safety

Go's strong typing catches errors at compile time. Work with JSON data safely and confidently.

Idiomatic Go

Generated code follows Go conventions with PascalCase exported fields and proper formatting.

Nested Support

Handles nested objects and arrays automatically, creating separate struct types as needed.

How to Convert JSON to Go

1

Paste JSON

Paste your JSON data into the editor or drag and drop a .json file

2

Click Generate

Navigate to the "Generate" tab in the output panel

3

Select Go

Choose "Go" from the language dropdown menu

4

Copy Code

Copy the generated Go structs to your project

Example: JSON to Go Conversion

Input JSON

{
  "user": {
    "id": 123,
    "name": "John Doe",
    "email": "john@example.com",
    "is_active": true,
    "roles": ["admin", "editor"],
    "profile": {
      "bio": "Software developer",
      "avatar_url": "https://example.com/avatar.jpg"
    }
  },
  "created_at": "2024-01-15T10:30:00Z"
}

Generated Go Structs

type Profile struct {
    Bio       string `json:"bio"`
    AvatarURL string `json:"avatar_url"`
}

type User struct {
    ID       int      `json:"id"`
    Name     string   `json:"name"`
    Email    string   `json:"email"`
    IsActive bool     `json:"is_active"`
    Roles    []string `json:"roles"`
    Profile  Profile  `json:"profile"`
}

type Root struct {
    User      User   `json:"user"`
    CreatedAt string `json:"created_at"`
}

JSON to Go Converter Features

Automatic JSON Tags

Every field gets the correct `json:"fieldname"` tag for proper marshaling with encoding/json.

Proper Go Types

Generates string, int, float64, bool, slices, and custom struct types based on your JSON data.

Nested Struct Support

Nested JSON objects become separate Go structs with proper type references.

PascalCase Fields

Field names are automatically converted to exported PascalCase while preserving original names in tags.

Array Handling

JSON arrays become Go slices ([]T) with proper element types inferred from the data.

100% Private

All processing happens in your browser. Your JSON data never leaves your computer.

Common Use Cases

REST API Development

Create request and response structs for your Go REST APIs. Works great with Gin, Echo, Fiber, and the standard library.

Microservices

Generate types for inter-service communication. Ensure type safety across your Go microservices architecture.

Configuration Files

Convert JSON config files to Go structs for type-safe configuration management with Viper or similar libraries.

Third-Party API Integration

Quickly create structs for external API responses. Parse JSON from any API into strongly-typed Go code.

Frequently Asked Questions

Is this JSON to Go converter free?

Yes, completely free. No registration required, no usage limits. Use it for any personal or commercial Go project.

Does it generate proper json tags?

Yes, all struct fields include proper `json:"fieldname"` tags that match the original JSON keys. This ensures correct serialization and deserialization with encoding/json.

Can it handle nested JSON objects?

Yes, nested objects are automatically converted to separate Go structs with proper type references. The generated code maintains the hierarchical structure of your JSON data.

What Go types are generated?

We generate appropriate Go types: string for strings, int/float64 for numbers, bool for booleans, []T for arrays, and custom struct types for nested objects.

Is my data secure?

Yes, all processing happens directly in your browser. Your JSON data is never sent to any server. The conversion runs entirely client-side using JavaScript.
