Cómo usar: JSON to Go
- Paste a JSON sample in the input — Go is already selected.
- Set the root type name and options such as optional fields and date detection.
- Copy the generated Go code into your project.
JSON to Go structs
Each JSON object becomes a Go struct with exported (capitalized) field names and json:"key" tags, so encoding/json maps the original keys — including snake_case and keys that aren’t valid Go names. Numbers become int64 or float64, arrays become slices, and optional fields get omitempty or pointer types so a missing value can be told apart from zero.
Decoding the JSON
Use json.Unmarshal(data, &v) or a json.Decoder for streams. Add DisallowUnknownFields() on the decoder when you want unexpected keys to fail loudly.
Private by design
The conversion runs entirely in your browser — API responses with customer or internal data are never uploaded.

Preguntas frecuentes
How are nested JSON objects converted to Go?
Each nested object becomes its own named struct, named after its key, and referenced from the parent. Arrays become typed lists of the element type.
What happens with fields that are missing or null in some items?
When you paste an array of objects, fields that are missing or null in some items are marked optional (nullable), so the generated code matches real API responses.
Is my JSON uploaded?
No. The conversion runs entirely in your browser, so API responses with private data never leave your device.
¿Puedo instalar JSON to Go como aplicación web y utilizarla sin conexión?
Sí. JSON to Go es una aplicación web instalable (PWA): se instala desde el navegador, no se descarga desde una tienda de aplicaciones. Haz clic en «Instalar aplicación» en la parte superior de esta página en Chrome o Edge (Windows, macOS, Linux, ChromeOS) o, en Android, utiliza «Compartir» → «Añadir a la pantalla de inicio» en iPhone y iPad, o «Archivo» → «Añadir al Dock» en Safari 17+ en un Mac. A continuación, se abrirá en su propia ventana con su propio icono y, como se ejecuta íntegramente en tu navegador, seguirá funcionando sin conexión. Firefox en el ordenador de sobremesa no permite instalar aplicaciones web. Cómo funciona la instalación.
