This tool converts JSON data into Go struct definitions.

Overview

The JSON to Struct Generator is a simple tool written in Go that generates Go struct definitions based on JSON input. It's useful for quickly creating Go struct types that match the structure of JSON data.

Features

• Converts JSON data to Go struct definitions
• Handles nested structures, arrays, and complex JSON data
• Copies generated struct definitions to the clipboard

Usage

Clone the repository and run the tool with the following command:

go run main.go <json-file path>

sample.json

{
  "name": "John",
  "age": 30,
  "cars": {
    "car1": "Ford",

        3
      ],
      "address": {
        "city": "New York",
        "zip_code": "10001",
        "coordinates": {
          "latitude": 40.7128,
          "longitude": 74.0060
