About this Tool

Convert JSON objects into Golang struct definitions with standard json struct tags instantly and privately.

Why Generate Go Structs from JSON?

In Golang, parsing JSON payloads using json.Unmarshal requires strongly-typed struct definitions decorated with json:"..." struct tags. Writing these manually for complex, multi-level REST APIs is error-prone and time-consuming. Our tool automates the process with strict Go types (int64, float64, string, bool, []T).

Recursive Struct Decomposition

Nested objects are automatically separated into distinct PascalCase Go struct types, allowing seamless reuse across your backend codebase.

100% In-Memory Processing

Your API payloads remain strictly confidential on your computer with zero telemetry.

Privacy Guarantee

The JSON to Go Struct Generator operates 100% locally in your web browser. Your JSON objects, arrays, and keys are processed entirely in-memory using Web Workers and JavaScript. No JSON data is ever transmitted across the network or stored on external servers, making it completely safe for sensitive enterprise payloads.
