Convert JSON to Go Struct Online
Defining Go structs by hand from a JSON API response is repetitive and time-consuming when payloads have many fields. This tool generates idiomatic Go struct definitions complete with json tags from any JSON object, handling nested objects, arrays, and primitive types correctly. Paste your JSON and get ready-to-use Go structs with proper PascalCase field names and snake_case JSON tags. Everything runs in your browser — no server, no data retention. This is especially useful when consuming external APIs or working with large configuration payloads in Go services.

FAQ
- Are json struct tags included?
- Yes. Each field includes a `json:"field_name"` tag matching the original JSON key, following Go conventions.
- How are nested objects handled?
- Nested JSON objects become nested Go structs, each defined separately so they can be reused across your codebase.
- What happens with arrays?
- JSON arrays become Go slices. The element type is inferred from the array contents.
