JSON to Go

Generate Go structs with JSON tags from any JSON sample. Handles nested objects, arrays and slices automatically.

Go types
package main

type Profile struct {
	Email string `json:"email"`
	Verified bool `json:"verified"`
}

type Root struct {
	Id int64 `json:"id"`
	Name string `json:"name"`
	Roles []string `json:"roles"`
	Profile Profile `json:"profile"`
}
