如何使用 Python 将这个嵌套的 JSON 转换为 Excel 或 CSV 文件

Question

所以我有这个嵌套的 json，由于它的形状，我正在努力转换成表格形式，它可能会变成 .xslx 或 .csv。

我试过这样做，但我没有工作。

# Load the JSON data into a pandas DataFrame
df = pd.read_json(response_data, typ='series')

# Convert the DataFrame to a flattened dictionary
flat_dict = pd.json_normalize(df.to_dict())

# Export the flattened dictionary to an Excel file
flat_dict.to_excel('output.xlsx', index=False)

json：

理想情况下，输出应该是这样的：

关于如何使用 Python 转换它有什么建议吗？可以是熊猫或任何其他模块。

Answer 1

您可以迭代第一级记录以创建单独的数据帧，然后将它们连接起来以获得预期的输出：

import json
import pandas as pd

data = json.loads(response_json)
df = pd.concat({k: pd.json_normalize(v) for k, v in data.items()}).droplevel(1)

输出：

>>> df
   Price  category  service.id service.name service.description  ... creditTO.duration  creditTO.Type creditTO.Tax  creditTO.total  creditTO.promotion
A    200       620          15          KAL         Description  ...                 6       standard           51             400               False
B    200       620          15          BTX         Description  ...                 9       standard           51             400               False
C    600       620          15          FLS         Description  ...                12       standard           51             400               False
D    705       620          15          TRW         Description  ...                18       standard           67             245               False

Answer 2

扩展到 Corralien 写的内容，尝试这样的事情：

import json
import pandas as pd

data = json.loads(response_json)
df = pd.concat({k: pd.json_normalize(v) for k, v in data.items()}).droplevel(1)

df = pd.concat((df, pd.concat({k: pd.json_normalize(v) for k, v in df['service.services'].items()}).droplevel(1).add_prefix('service.')), axis=1).drop(columns='service.services')

假设您总是在

service.services

列下有一个列表。

输出：

|    |   Price |   category |   service.id | service.name   | service.description   | service.Validity   |   service.order | service.selection   |   creditTO.id |   creditTO.duration | creditTO.Type   |   creditTO.Tax |   creditTO.total | creditTO.promotion   |   service.id | service.financeable   | service.Execution   |   service.serviceId | service.label   |   service.benefit.id | service.benefit.name   | service.benefit.Priced   |
