Features

  • JSON File Upload: Upload a .json file directly — read locally in your browser, nothing is sent to any server.
  • Drag & Drop: Drag and drop a JSON file onto the drop zone for quick loading.
  • Struct Generation: Creates Go struct definitions compatible with standard encoding/json.
  • Tagging: Automatically adds `json:"key"` tags.
  • Nested Structs: Handles nested objects by defining inline array rules or sub-structs (simplified).
  • Type inference: Maps JSON types to Go types (string, int, float64, bool, []interface{}).

How to Use

  • Upload a JSON file using the file picker, or drag & drop a file onto the drop zone.
  • Alternatively, paste JSON into the input area.
  • The tool generates the corresponding Go struct.
  • Copy the code to your Go application.
