Generate Go struct declarations from a representative JSON object or array, including nested types, exported field names, and original-property json tags.
Choose the package and root type names, then generate a complete Go source file with valid exported fields and original-property json tags. Review sample-dependent choices before using the types in an application.
Use one JSON object or any non-empty JSON array. A top-level array becomes a named slice, and every object item in an array contributes to the inferred fields. Property names must be representable by Go's standard encoding/json struct tags; unsupported names produce an error instead of being silently changed.
Object arrays are merged across all supplied items. A field seen in only some items is still generated from the values that are present. The omitempty option changes every json tag; it does not add pointers or validate required fields.
A null value, an incompatible mixture of value types, or an array containing incompatible values becomes any. An empty array becomes []any because the sample does not reveal its element type.
Treat the result as a sample-based starting point. Check optional fields, time strings, map-like objects, numeric ranges, and identifiers that may exceed the exact range of a JSON number before adding the types to your project.
No. The JSON is parsed and converted in this browser tab by this tool. It is not uploaded to a server.
