将目录中所有 .json 文件的 JSON 转换为 XLSX

Question

面临读取与程序可执行文件位于同一目录下的所有json文件的问题，选择这些文件中的某些元素并将它们保存在一个Excel文件中.

例如，我有很多 JSON 个文件，例如：

第一个文件

{"General":{"Code":"AAIC-PB","Type":"Preferred Share","Name":"Arlington Asset Investment Corp"}, "Highlights":{"MarketCapitalization":211528800,"MarketCapitalizationMln":211.5288}}

第二个文件

{"General":{"Code":"A","Type":"Common Stock","Name":"Agilent Technologies"}, "Highlights":{"MarketCapitalization":567456,"MarketCapitalizationMln":222.567}}

我想获取特定键及其值并将其放入 excel。例如，从 General 中获取 CODE，从 Highlights 中获取 MarketCapitalization所以最后肯定是这样的:

本人是python新手，求懂的人帮忙。谢谢！

Answer 1

这应该适合您，使用 glob 查找目录中的所有 json 文件，然后对每个文件使用 json 打开这些文件并组合“亮点” " 和 "General" 键并将所有生成的词典添加到列表中，然后保存到 csv

import csv
import json
from glob import glob

# function to open json files
def read_json(path):
    with open(path, 'r') as file:
        return json.load(file)

# function to save csv files
def write_csv(data, path):
    with open(path, 'w') as file:
        # get all the keys
        fieldnames = set().union(*data)
        writer = csv.DictWriter(file, fieldnames=fieldnames, lineterminator='\n')
        writer.writeheader()
        writer.writerows(data)

# use glob to find all the *.json files in the folder named json_dir
json_files = glob('./json_dir/*.json')

rows = []

for json_file in json_files:
    # read the json file
    json_data = read_json(json_file)
    # combine General and Highlights into the same dictionary
    rows.append({**json_data['General'], **json_data['Highlights']})

# write the csv to json_data.csv
write_csv(rows, './json_data.csv')

输出：
