如何将json类型的数据转换为csv格式

import csv
import json

# JSON数据
json_data = '''
[
    {
        "name": "John",
        "age": 30,
        "city": "New York"
    },
    {
        "name": "Jane",
        "age": 25,
        "city": "San Francisco"
    },
    {
        "name": "Tom",
        "age": 35,
        "city": "Seattle"
    }
]
'''

# 解析JSON数据
data = json.loads(json_data)

# 创建CSV文件并打开以便写入数据
with open('output.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)

    # 写入CSV头部
    writer.writerow(data[0].keys())

    # 遍历JSON数据并写入CSV文件
    for item in data:
        writer.writerow(item.values())

# 关闭CSV文件
csvfile.close()
