Go Struct ⇄ JSON Converter
Instantly generate production-ready Go struct definitions from any JSON payload, complete with typed fields and custom JSON tags. Bi-directional parsing allows you to perfectly render JSON responses directly from nested Golang structs.

Guide & Insights
The Ultimate Golang Type Studio
Stop manually typing out massive Go structs for random API responses. Our Go Struct ⇄ JSON Engine works as a dual-directional compiler running directly in your browser. Seamlessly paste a huge JSON payload and instantly get production-ready structs, or define complex Go types and effortlessly scaffold mock JSON responses.
Instant Inference Engine
Paste any valid JSON object or array, and we'll instantly infer Golang scalar types, nested structs, and slices. We automatically convert snake_case keys into standard Go CamelCase struct fields with proper `json:"..."` metadata tags.
Reverse Architecture
Developing a new API endpoint? Write out your Golang structs first, click Go → JSON, and we'll traverse your custom types and slices to generate a perfectly mapped, deeply nested mock JSON hierarchy filled with safe default values.
Client-Side Guarantee
Whether you are converting highly sensitive customer information payload or proprietary internal schemas, all parsing happens 100% locally in your browser memory. No data is ever transmitted to external servers.
