Generate Go Structs from API Response

This example generates Go structs with JSON tags from a typical REST API response. The pre-filled JSON represents a user object with nested address, array of roles, and array of post objects. Switch to Go mode to see the generated structs.

What You Get

The tool produces:

How to Use

  1. The example loads with a sample API response and Go mode pre-selected
  2. Inspect the generated Go structs and their JSON tags
  3. Copy the structs and paste them into your Go project
  4. Replace with your actual API response to generate structs for your endpoints

Real-World Pattern

Go structs with JSON tags are the standard way to deserialize API responses in Go. The generated code works directly with json.Unmarshal and json.NewDecoder. Use omitempty for fields that may not always be present in the response.
