如何将csv转换为复杂的json

import csv
import json

def csv_to_json(csv_file):
    # 读取CSV文件
    with open(csv_file, 'r') as file:
        reader = csv.DictReader(file)
        # 解析CSV数据
        data = [row for row in reader]

    # 构建JSON数据结构
    json_data = {
        'data': []
    }
    for row in data:
        json_row = {
            'id': int(row['id']),
            'name': row['name'],
            'age': int(row['age']),
            'email': row['email'],
            'address': {
                'street': row['street'],
                'city': row['city'],
                'state': row['state'],
                'zip': row['zip']
            }
        }
        json_data['data'].append(json_row)

    # 导出为JSON字符串
    json_str = json.dumps(json_data, indent=4)
    return json_str

# 示例用法
csv_file = 'data.csv'
json_str = csv_to_json(csv_file)
print(json_str)
