json转excel python

pip install pandas openpyxl

简单实现

import pandas as pd# JSON 数据
data = [{"id": 1,"age": 3,"male": True,"address": "shanghai"},{"id": 2,"age": 50,"male": True,"address": "Washington D.C."},{"id": 3,"age": 15,"male": False,"address": "hongkong"},{"id": 4,"age": 19,"male": False,"address": "newyork"},{"id": 5,"age": 38,"male": True,"address": "beijing"}
]# 转换为 DataFrame
df = pd.DataFrame(data)# 保存为 Excel 文件
df.to_excel("output.xlsx", index=False)print("✅ JSON 数据已成功保存为 output.xlsx")
