JSON to Go Struct
Convert JSON objects to Go struct definitions with proper types and json tags.
Frequently Asked Questions
How does the JSON to Go conversion work?
The tool parses your JSON input, inspects each key-value pair, and infers the corresponding Go type. Nested objects become nested structs, arrays become slices, and primitive types map to string, int, float64, or bool. JSON struct tags are automatically added.
How are field names converted?
JSON keys are converted from camelCase or snake_case to PascalCase for Go exported fields. For example, 'firstName' becomes 'FirstName' and 'user_id' becomes 'UserID'. Common abbreviations like ID, URL, API, HTTP are uppercased.
How are null values handled?
JSON null values are mapped to pointer types in Go (e.g., *string, *int). If a value is null, the tool uses *interface{} by default since the actual type cannot be determined from null alone.
Does it handle arrays with mixed types?
Yes. If an array contains elements of different types, the tool uses []interface{} as the Go type. If all elements share the same type, it uses a typed slice like []string or []int.
Can I use this for production code?
The generated structs are a great starting point. You may want to review pointer types, add omitempty tags, or adjust naming conventions for your project. Always validate the output matches your actual data model.
