Convert JSON to Go online, free. JSON is the dominant data-interchange format for web APIs and config. Go structs with field tags marshal cleanly to and from data formats. JSON to Go conversion parses your JSON against the ECMA-404 / RFC 8259 grammar (https://www.rfc-editor.org/rfc/rfc8259), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Go types as structs with json field tags following the The Go Programming Language Spec conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Go microservices, CLIs and encoding/json struct mapping.
It maps the full structure of your JSON onto idiomatic Go types, following the The Go Programming Language Spec conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste JSON and generate Go types from Go immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested JSON objects, tables and arrays are mapped faithfully onto Go, including nested types and optional fields.
Your JSON never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
Example: JSON → Go
type User struct {
Name string `json:"name"`
Age int `json:"age"`
Email string `json:"email,omitempty"`
}Converting JSON to Go is simple with our free online tool. Just paste or upload your JSON data, click the "Convert to Go" button, and get instant results. The conversion happens in your browser, ensuring privacy and speed. No registration or installation required.
Yes! Our JSON to Go converter is completely free to use with no limitations. You can convert unlimited files, and there are no hidden fees, registration requirements, or usage restrictions. All processing happens locally in your browser for maximum privacy.
Yes, our tool can handle JSON files of various sizes. Since the conversion happens in your browser, the limit depends on your device's memory. Most modern browsers can handle files up to several megabytes without issues. For very large files, ensure you have sufficient RAM available.
Absolutely! Your data never leaves your device. All JSON to Go conversion happens locally in your browser using JavaScript. We don't upload, store, or transmit your data to any server. This ensures complete privacy and security for sensitive information.
JSON (JavaScript Object Notation) (JSON) and Go (Golang) structs (Go) are different serialization formats, each with its own syntax and strengths. Data often needs to move between them when integrating tools, APIs, or configuration systems that expect a specific format. This converter maps the structure of your JSON onto valid Go so you can use it wherever Go is required.
Yes! Our JSON to Go converter works perfectly on mobile devices (smartphones and tablets) as well as desktop computers. The responsive design ensures a smooth experience on any screen size. Just open https://tools.seagit.com/json-to-go in your mobile browser.
Yes, our tool includes built-in JSON validation. If your JSON data contains syntax errors, you'll receive clear error messages indicating what needs to be fixed. This helps ensure your converted Go output is accurate and valid.
