FAQ
Common questions and answers about this topic.
How does the JSON to Go type mapping work?
JSON strings map to Go string, numbers to float64 (or int if whole numbers), booleans to bool, null to a pointer type, arrays to slices, and nested objects to nested structs. The converter analyzes your JSON data to infer the most appropriate Go type for each field.
How are nested JSON objects handled?
Each nested JSON object is converted into a separate Go struct type. The converter automatically generates meaningful struct names based on the field names and creates proper type references between parent and child structs.
Are json tags automatically generated?
Yes, the converter automatically adds json struct tags to every field, using the original JSON key name. For example, a JSON field "user_name" generates a Go field with the tag `json:"user_name"`, ensuring correct serialization and deserialization.
Is my data sent to any server?
No, the JSON to Go struct conversion is performed entirely in your browser using JavaScript. Your JSON data stays on your device and is never uploaded to any server.
