Convert JSON to Idiomatic Go Structs

Generate Go (Golang) structs with json struct tags, nested structs, and standard acronym casing.

JSON to Go Struct Generator

Convert JSON payloads into idiomatic Go (Golang) structs with json struct tags.

JSON Input

Root Go Struct Name

Generated Go Structs (Golang)

type UserPayload struct {
	UserID           int64          `json:"user_id"`
	UserName         string         `json:"user_name"`
	EmailAddress     string         `json:"email_address"`
	IsActive         bool           `json:"is_active"`
	HourlyRate       float64        `json:"hourly_rate"`
	IPAddress        string         `json:"ip_address"`
	APIKeys          []string       `json:"api_keys"`
	ServerConfig     ServerConfig   `json:"server_config"`
}

type ServerConfig struct {
	HTTPPort         int64          `json:"http_port"`
	EnableTls        bool           `json:"enable_tls"`
}

About This Tool

JSON to Go Struct Generator parses JSON objects and creates strongly-typed Go struct declarations with json struct tags, aligning field names with Go naming conventions and standard acronyms (ID, URL, IP).

Key Features

Generates Go struct tags (json:"...")

Idiomatic PascalCase naming with acronym capitalization (ID, IP, URL)

Supports nested structs and primitive slices ([]string, []int64)

How to Use This Tool

Paste your JSON payload into the input area.
Enter the root Go struct name.
Copy the generated Go struct code.

Why Use This Tool

Save time writing boilerplate structs when building Golang microservices and API clients.
Follows Go standard library conventions including uppercase acronyms (ID, URL, API).

Pro Tips

Pass structs directly into json.Unmarshal(data, &payload) for zero-boilerplate decoding

Frequently Asked Questions

How does the tool handle unknown or null values in Go?

Null or untyped fields default to interface{} (or any in Go 1.18+), allowing flexible unmarshaling.
