JSON → Go
JSON Input
Go Output
Generate Go structs from JSON instantly. Includes JSON struct tags and handles nested objects and arrays. Runs in your browser — your data never leaves your machine.
All conversion happens in your browser using JavaScript. Nothing is uploaded to any server. Safe for sensitive business data.
Every field includes a JSON struct tag so your Go structs work seamlessly with encoding/json marshal and unmarshal.
Nested JSON objects are automatically extracted into separate Go structs. Arrays of objects get their own typed structs too.
Paste your JSON into the left panel and Go struct code appears instantly on the right. The converter maps JSON objects to Go structs with exported fields and json:"..." struct tags. Nested objects become separate structs, and arrays are typed as slices. You can customize the root struct name and copy or download the generated code.
Use this tool when building Go APIs or microservices that consume or produce JSON, when you need request/response structs for HTTP handlers, or when working with JSON configuration files in Go applications. The generated structs include proper JSON tags and work directly with Go's encoding/json package for marshaling and unmarshaling.
`json:"fieldName"`) that map directly to your JSON keys.[]T) with the appropriate element type inferred from the array contents.
