JSON to Go Struct
JSON to Go Struct is a free online generator that converts JSON data into Go struct definitions in real time. It produces field names, types, and json tags automatically, handles nested structures, and offers an inline-struct option to choose between inlined anonymous structs and separate named ones.
The conversion runs entirely in your browser — your JSON is never uploaded, so internal API data stays private. It's free with no sign-up, perfect for Go developers generating unmarshal-ready structs from API responses without hand-writing json tags.
How to Use
- Paste or type your JSON into the left editor
- The Go struct code is generated automatically on the right
- Toggle the inline-structs option to change how nested objects are rendered
- Copy the generated structs into your Go project
FAQ
Is the JSON to Go Struct converter free?
Yes, it's completely free with no limits and no account required.
Is my JSON data uploaded to a server?
No. Everything runs locally in your browser, so even internal API payloads never leave your machine.
Do the generated structs include json tags?
Yes. Every field gets a matching json tag, and field names are converted to Go-style CamelCase, so the output works directly with encoding/json.
What does the inline-structs option do?
When enabled, nested objects are embedded as anonymous structs inside the parent; when disabled, they become separate named structs referenced by the parent. Pick whichever matches your code style.
