How to Convert JSON to Go Structs - Step by Step Guide

Step 1

Input Your JSON Data

Start by adding your JSON data that needs to be converted to Go structs. The tool analyzes the structure to generate appropriate struct definitions.

Example: Try This JSON Data

Copy and paste this JSON example to see how it works: 🐹

{
  "server": {
    "id": 42,
    "name": "web-server-01",
    "hostname": "api.example.com",
    "port": 8080,
    "isActive": true,
    "tags": [
      "production",
      "api",
      "critical"
    ],
    "config": {
      "maxConnections": 1000,
      "timeout": 30,
      "enableLogging": true
    }
  }
}
Step 2

Configure Go Options

Customize how your JSON is converted to Go structs! ⚙️ Choose naming conventions and features.

•
JSON tags: Generate JSON tags for marshaling and unmarshaling
•
Struct generation: Create clean Go structs with proper field types
•
Nested structures: Handle complex JSON hierarchies with embedded structs
•
Type mapping: Automatic Go type mapping from JSON data types
Step 3

Get Generated Go Code

Watch the transformation! ✨ Your JSON structure becomes clean, idiomatic Go structs.

Go Code Output

Your JSON becomes these Go structs:

package main

type Config struct {
    MaxConnections int  `json:"maxConnections"`
    Timeout        int  `json:"timeout"`
    EnableLogging  bool `json:"enableLogging"`
}

type Server struct {
    ID       int      `json:"id"`
    Name     string   `json:"name"`
    Hostname string   `json:"hostname"`
    Port     int      `json:"port"`
    IsActive bool     `json:"isActive"`
    Tags     []string `json:"tags"`
    Config   Config   `json:"config"`
}

type Root struct {
    Server Server `json:"server"`
}
Step 4

Copy or Download Go Code

Perfect! Now you can use your Go structs in your applications for JSON processing. 🚀

What is JSON to Go Conversion? 🔄

JSON to Go conversion transforms JSON data structures into Go structs with proper JSON tags for marshaling and unmarshaling. This process analyzes JSON structure and generates idiomatic Go code that can parse, validate, and work with JSON data using Go's built-in encoding/json package.

The generated Go structs include proper field names, JSON tags, and type mappings, enabling seamless JSON serialization and deserialization in Go applications and microservices.

Frequently Asked Questions

What Go struct tags are generated for JSON?

The tool generates JSON struct tags like `json:"fieldName"` for each field following Go's encoding/json standards. These tags enable Go's encoding/json package to properly marshal and unmarshal JSON data, handling field name mapping between JSON and Go conventions. Make sure to validate your JSON before generating structs.

Can I use the generated structs with popular Go frameworks?

Yes! The generated Go structs work seamlessly with Gin, Echo, Fiber, and other Go web frameworks. They integrate perfectly with middleware, validation libraries, and database ORMs like GORM for complete application development.

How are nested JSON objects handled in Go structs?

Nested JSON objects become separate Go struct types with proper relationships. The tool creates a struct hierarchy that mirrors your JSON structure, with parent structs containing fields of child struct types.

What Go data types are used for JSON values?

JSON strings become Go string, numbers become int/float64, booleans become bool, arrays become []T slices, and objects become custom structs. The tool follows Go conventions for idiomatic type mapping.

Are the generated structs compatible with Go modules?

Absolutely! The generated Go structs follow standard Go conventions and work perfectly with Go modules, go.mod files, and modern Go development practices. They're ready for production use in any Go project.

Is the JSON to Go converter free to use?

Yes, completely free with no limitations on JSON complexity, struct generation, or usage frequency. No registration required, and you can generate unlimited Go structs from JSON data at no cost.
