JSON to Go Struct
Generate Go structs with json tags from JSON. Free and private: runs in your browser.
Paste sample JSON to get Go struct definitions with idiomatic field names (ID, URL).
Runs entirely in your browser. Nothing you paste is uploaded or stored.
Use cases
- Move data between APIs, config files and databases.
- Bootstrap models from a sample API response.
- Save time on repetitive hand-written boilerplate.
Frequently asked questions
Why are null fields pointers?
A pointer distinguishes "missing or null" from the zero value, and omitempty leaves it out when marshalling.
Is the JSON to Go Struct free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Should I use the generated output as-is?
Treat it as a strong starting point. Types are inferred from your sample, so review nullability, naming and edge cases before committing it.
