✨ Why Developers Choose This JSON → Go Generator

  • 🚀 Instant conversion – Paste JSON, click Convert, get ready‑to‑use Go structs.
  • 🧠 No duplicate types – Nested objects are detected and reused; each unique structure becomes a separate Go struct.
  • 📦 ZIP export (models folder) – Download all generated structs as separate `.go` files inside a `models/` folder.
  • 🎨 Ace editor with syntax highlighting – Edit JSON and Go with full highlighting.
  • 🔒 100% client‑side – No data leaves your browser. Perfect for API specs or configs.
  • 📂 Upload JSON file – Load any `.json` file directly; auto‑prettified and ready.

📖 How to Convert JSON to Go Structs

1. Enter your JSON

Paste JSON into the left editor, or click “Upload JSON” to load a file.

2. Choose options

Select JSON tag options: omitempty, string tag for numbers, pointers for nullable fields, and set a package name.

3. Convert & export

Click Convert to Go – the right panel shows your Go code. Use Copy or Export ZIP to download a `models/` folder with each struct as a `.go` file.

🎯 Common Use Cases for JSON to Go Conversion

  • API integration – Generate Go structs from API response JSON for type‑safe decoding.
  • Microservices – Convert OpenAPI/Swagger JSON to Go models.
  • Configuration – Create Go structs for JSON config files.
  • Testing – Quickly create mock structs from example JSON.

❓ Frequently Asked Questions About JSON to Go Conversion

Does this tool handle nested objects and arrays?

Yes. The converter recursively creates separate Go structs for nested objects. Arrays become slices; arrays of objects become slices of the appropriate struct type.

What JSON tag options are available?

You can add omitempty to skip zero values during marshaling, and ,string to force numeric fields to be encoded as JSON strings. Pointers can be used for nullable fields.

Can I set a custom package name?

Yes – the “package name” text field lets you set any valid Go package identifier (default is `main`).

Is my JSON data sent to any server?

Never. Everything runs locally in your browser – 100% client‑side.

Can I export all structs as separate files?

Yes. Click Export ZIP to download a `models/` folder with each generated Go struct as a separate `.go` file.
