- Use the struct in your Go project for JSON marshaling/unmarshaling
What are json tags in Go structs?
Json tags are annotations that tell Go's encoding/json package how to map struct fields to JSON keys. They're specified using backticks like `json:"fieldName"` and enable proper JSON serialization and deserialization.
How does the tool handle nested JSON objects?
The converter creates separate struct definitions for each nested object. For example, if your JSON has a user with an address, it generates both User and Address structs with proper type references.
What Go types are generated for JSON values?
The tool maps JSON types to Go types: strings become string, integers become int, decimals become float64, booleans become bool, arrays become slices, and objects become nested structs.
How are null values handled?
Null values in JSON are converted to interface{} in Go, which can hold any value including nil. For more specific handling, you may want to use pointer types or custom nullable types.
Can I use this for API response modeling?
Absolutely! This is one of the most common use cases. Simply paste a sample API response and get instant Go structs ready for use with json.Unmarshal() in your Go code.
Are the field names properly capitalized?
Yes! Go requires exported fields to start with uppercase letters. The tool automatically capitalizes field names while preserving the original JSON key names in the json tags.

JSON
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is based on a subset of JavaScript syntax but is language-independent.
Go
Go (also known as Golang) is a statically typed, compiled programming language designed at Google. It emphasizes simplicity, efficiency, and built-in support for concurrent programming through goroutines and channels.
Autonomous Driving
Autonomous Driving is a technology that enables vehicles to navigate and operate without human intervention by using a combination of sensors, artificial intelligence, and control systems. It encompasses various levels of automation defined by SAE International, ranging from Level 0 (no automation) to Level 5 (full automation), where the vehicle can handle all driving tasks in all conditions without any human input.
Bearer Token
Bearer Token is an access token type used in HTTP authentication where the client presents a token to access protected resources. The term 'bearer' means that any party holding the token can use it to access the resource, without needing additional proof of identity.
JSON Schema
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It describes the structure, constraints, and documentation of JSON data, enabling automated validation and documentation generation.
