FAQ
Common questions and answers about this topic.
How does a Go struct relate to JSON?
A Go struct defines a typed data structure with named fields, while JSON is a text-based data format. Go's encoding/json package maps struct fields to JSON keys using field names or json struct tags. This converter generates sample JSON output that matches your struct definition.
How are struct tags handled?
The converter reads json struct tags to determine the JSON key name. For example, a field with `json:"user_name"` will appear as "user_name" in the JSON output. Fields tagged with `json:"-"` are omitted. If no json tag is present, the field name is used as-is.
Are nested structs supported?
Yes, the converter fully supports nested struct definitions, slices of structs, maps, and embedded structs. Each nested struct is converted to a corresponding nested JSON object with appropriate sample values for each field type.
Is my data sent to any server?
No, the Go struct to JSON conversion runs entirely in your browser. Your Go struct definitions are parsed locally with JavaScript and never sent to any server.
