About JSON to Go Struct
When building APIs, SDKs, and backend services in Go, one of the repetitive tasks is turning JSON payloads into usable struct definitions. Hand-writing those types becomes slow once nested objects, arrays, and optional values start piling up.
This generator reads your sample JSON and turns objects into structs, arrays into slices, and primitive values into practical Go types with `json` tags ready for production code. It includes optional omitempty tag support to handle optional fields based on your API schema design.
It is not meant to replace full schema management, but extremely useful for creating reliable first drafts, documentation snippets, and mock structures. You can customize the root type name to match your naming conventions. All processing runs locally in your browser, making the tool suitable for internal payloads and sensitive business data that should never be uploaded to external services.
How to use JSON to Go Struct
- Paste a sample JSON payload into the input area.
- Customize the root struct name and optionally enable omitempty tags.
- Copy the generated Go structs into your codebase.
Benefits of JSON to Go Struct
- Create a practical first draft of Go types in seconds.
- Optional omitempty tags support flexible API schema modeling.
- Generate copy-paste-ready structs with json tags while keeping sensitive data secure in-browser.
