JSON → Go Struct Generator
Paste JSON data and generate Go structs with proper json tags. Handles nested objects, arrays, and Go naming conventions.
JSON
Go Struct
💡 Definition
Go Structs
- Go structs define the shape of data objects with type annotations and json tags for serialization.
- This tool converts JSON to properly formatted Go structs following Go naming conventions (PascalCase) with json field tags.
📖 How to use
Step by Step
- Paste a JSON object in the left panel
- Go struct with json tags appears on the right
- Nested objects become separate structs
- Field names follow Go conventions (PascalCase)
🎯 Use cases
When to use
- Building Go APIs from JSON specifications
- Converting API responses to Go types
- Learning Go struct syntax
- Prototyping Go data models
Frequently Asked Questions
How are Go types inferred?▾
Strings → string, integers → int64, decimals → float64, booleans → bool, null → interface{}, arrays → []Type, nested objects → separate structs.
What are json tags?▾
json tags like `json:"field_name"` tell Go's JSON encoder/decoder how to map struct fields to JSON keys. They handle the naming difference between Go's PascalCase and JSON's camelCase/snake_case.
