What is JSON to Go Converter?
Need to generate Go structs from your JSON (JavaScript Object Notation) data? This tool does that instantly. Perfect for Go developers working with microservices, APIs, or cloud applications who need to deserialize JSON into strongly-typed Go structs. Generate structs, tags, and type definitions automatically.
According to Go documentation, structs and tags are essential for JSON marshaling and unmarshaling. Our converter analyzes your JSON structure and generates proper Go structs. First, validate your JSON using our JSON Validator, then convert it to Go. You can also format your JSON with our JSON Formatter first if needed.
Everything happens in your browser – your JSON never leaves your computer. Convert, download, and use your Go structs right away.
What Makes This Tool Different
Automatic Struct Generation
We analyze your JSON structure and automatically generate Go structs. JSON objects become structs, arrays become slices, everything gets proper Go types.
JSON Tags
Generate Go structs with JSON tags for proper marshaling and unmarshaling. Works great with Go's encoding/json package for JSON processing.
Package Support
Configure package names to match your project structure. Generate code that fits seamlessly into your existing Go project organization.
File Upload Support
Got a big file? Just upload it. Works great for converting those massive JSON configs or data files without copy-pasting.
Download Go
One click to download your Go file. Drop it into your Go project and start using it. Perfect for microservices, APIs, or cloud applications.
Clean Code Output
The generated Go code is clean and well-formatted. Structs are properly named, fields are typed correctly, and the code follows Go conventions.
How It Works
Paste or Upload JSON
Paste your JSON into the left editor, or click "Upload" to load a file. The JSON should be valid – use our JSON Validator first if you're not sure. You can also click "Sample" to see an example.
Configure Options
Set your struct name, package name, and choose whether to use JSON tags or pointers. These settings customize the generated Go code to match your project's conventions.
Download or Copy
Click "Download" to save the Go file, or "Copy" to copy it to your clipboard. The Go code is ready to use in your project. Drop it into your Go project and start using it.
When You'd Actually Use This
Microservices
Generate Go structs from JSON API responses for microservices. Create data models for JSON-based APIs or configurations. Perfect for Go's microservices architecture.
API Development
Create Go structs from JSON data for API development. Generate data models for JSON-based APIs or integrations. Perfect for Go's API development needs.
Cloud Applications
Generate Go structs from JSON data for cloud applications. Create data models for JSON-based cloud services or configurations. Perfect for Go's cloud-native development.
Code Generation
Generate Go code from JSON data structures. Perfect for creating data models, DTOs, or entity structs from JSON schemas or API responses.
Common Questions
Is my JSON data stored?
Nope. Everything happens right in your browser. Your JSON never leaves your computer – we don't even see it.
How are JSON objects handled?
JSON objects become Go structs. Properties become struct fields, and nested objects become nested structs or references. Arrays become Go slices.
Can I use the generated Go code?
Yes. The generated Go code is valid and ready to use. Drop it into your Go project and start using it. You may want to review and refine the structs for your specific use case.
What about JSON tags?
You can enable JSON tags in the configuration options. This generates Go structs with JSON tags for proper marshaling and unmarshaling with Go's encoding/json package.
Does it work with large JSON files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium JSON structures convert instantly. Really huge structures might take a few seconds.
What Go version is supported?
The generated code works with Go 1.13 and later. It uses standard Go features and follows Go conventions for maximum compatibility.
Other JSON Tools You Might Need
Conversion is just one JSON task. Here are other tools that work well together:
