JSON to Go Struct Converter
Developer
Paste any JSON object or array and get a ready-to-use Go struct definition with the correct field types (string, int64, float64, bool), nested structs, slices, and `json:"..."` tags. Everything runs locally in your browser — your JSON is never uploaded.
How to use
- Paste or type your JSON into the input box.
- Optionally rename the root struct (defaults to AutoGenerated).
- Copy the generated Go struct from the output box.
Frequently asked questions
- How are numbers typed?
- Whole numbers become int64 and numbers with a decimal point become float64. Adjust manually if you need a narrower type.
- What happens with null or empty arrays?
- null values and empty arrays map to interface{} since their type can't be inferred from the sample.
- Is my JSON sent anywhere?
- No. Conversion happens entirely in your browser; nothing is uploaded.
