Loading JSON to Go Converter...
Convert JSON to Go structs instantly with proper types, JSON tags, and nested structs. Perfect for API integration and data modeling.
After years of manually writing Go structs for API responses, I decided to build a better solution.
Let me be honest — writing Go structs by hand is tedious and error-prone. Especially when dealing with complex nested JSON structures.
Working on a large Go microservices project with 50+ API endpoints, I found myself spending hours manually typing out structs for every API response. Every time the API changed, I had to update all my structs. It was tedious, frustrating, and a huge productivity killer.
I built this tool to solve my own problem. After 850,000 struct generations and counting, it's clear that many Go developers face the same challenge. This tool automatically generates accurate Go structs from any JSON, saving hours of manual work.
Under the hood, I built a recursive JSON parser that analyzes value types and creates appropriate Go type definitions. The parser handles edge cases like empty arrays, null values, and deeply nested structures gracefully.
The editor uses CodeMirror 6, a powerful and lightweight code editor that provides excellent syntax highlighting, auto-completion, and a smooth editing experience right in your browser. All processing happens locally using Web Workers for optimal performance.
From solo developers and freelancers to teams at Fortune 500 companies. Anyone working with Go who needs to convert JSON to type-safe structs without the boilerplate.
No account needed. No tracking. No AI training on your data. No data collection. Just a tool that does one thing exceptionally well — converting JSON to Go structs.
— Built by a Go developer, for Go developers
Transform your JSON into Go structs in just a few clicks
Enter Your JSON Paste your JSON data, upload a .json file, or click on any example. Our editor supports syntax highlighting and auto-formatting.
Configure Options Set your package name and root struct name. The package defaults to 'main' for standalone apps.
Click Convert Hit the Convert button or use ⌘+Enter (Ctrl+Enter). Our parser analyzes your JSON and generates proper Go structs.
Copy or Download Copy the generated struct to your clipboard or download as a .go file. Use it immediately in your Go project.
Everything you need to generate perfect Go structs
How developers use JSON to Go Converter
Stop writing Go structs manually. Generate them instantly from JSON and focus on building your application.
Eliminate manual typing mistakes. Our generator creates accurate Go types that match your data structure.
Your JSON never leaves your browser. No server uploads, no tracking, complete privacy.
Perfect for beginners learning Go. See how JSON structures translate to Go structs.
Generate structs for REST APIs, GraphQL responses, or any JSON data source.
Generated structs follow Go best practices and are ready to use in production.
Automatic JSON tags mean you can marshal/unmarshal without extra work.
No installation required. Use it directly in your browser, anywhere, anytime.
Everything you need to know about JSON to Go conversion
JSON to Go converter is a developer tool that automatically transforms JSON data into Go struct definitions. It analyzes your JSON structure and generates accurate Go code that you can use in your projects for type safety.
Yes, completely free! No signup required, no hidden costs, and no limitations on usage. We believe in making developer tools accessible to everyone.
Full support for string, int, float64, bool, nested structs, and slices. The tool automatically detects the correct type based on your JSON values.
Absolutely! Our converter recursively processes deeply nested JSON objects, generating proper nested Go structs for all levels.
JSON arrays become Go slices with the appropriate element type. If the array contains objects, it generates a slice of structs.
Yes! Your data never leaves your browser. All conversions happen locally on your device. We don't store, process, or transmit your JSON data to any server.
Yes! The generated Go structs follow Go best practices and are production-ready. They include JSON tags for marshaling/unmarshaling.
Empty arrays become []interface{} since Go can't infer the type. You can easily replace 'interface{}' with the correct type after generation.
Yes! Use the Package Name input field to set your preferred package name. Default is 'main' for standalone applications.
We automatically add json:"fieldname" tags to all fields. This allows you to marshal and unmarshal JSON directly with the generated structs.
Our tool can handle JSON files up to 10MB efficiently. For larger files, we recommend splitting them into smaller chunks.
Yes! The generated code works with any Go module. Just copy the structs into your existing codebase.
