JSON to Go Struct
Paste any JSON object or array and generate matching Go structs. Field names are capitalized to be exported and the original keys are preserved in the `json:` tag. Nested objects are extracted into their own top-level structs, mixed-type or null fields fall back to `interface{}`. Arrays of objects produce a `[]Struct` slice, with element type inferred from the first object. Runs entirely in your browser — free, online, no upload.
