我有更复杂的 JSON，我正在尝试将其转换为 CSV。
我从这里和其他页面尝试了几个示例，但我无法弄清楚一些细节。我尝试使用熊猫，但我不确定如何处理嵌套列表。
以下示例是 Zendesk 的一张票。我将有一个文件，其中每一行是一张票。
我想以 CSV 格式获取每张票的字段，其中每一行代表该字段的值。基本扁平结构。示例：
id,via,created at,subject,description,自定义字段id1,自定义字段id2,请求者等

我想出了如何打印 JSON 中的记录。
import pandas as pd
df = pd.read_json('./test.json', orient='records')
df.to_csv('json_converted_to_csv.csv', index = None, header=True)
现在我想弄清楚如何展平特定的数组。例如，如何将“custom_fields”展平并以平面结构中的 id 和 value 结束。
感谢您的帮助。
答案 0 :(得分：0)
获得一个 253 列的数据框。 df.to_csv() 获取 CSV
null = None
false = False
true = True
js = # the JSON in your question
df = pd.json_normalize(js)
答案 1 :(得分：0)
我发现这个解决方案是将更复杂的 JSON 转换为 CSV 的通用方法，包括扁平化 JSON。
import json
import pandas as pd
#read JSON from file
with open('./export-2021-02-03-0452-1094680-36000530163187bb.json') as f:
data = json.load(f)
#flatten the JSON to any level. In this case level 2.
df = pd.json_normalize(data,max_level=2)
#save it to CSV
df.to_csv('file.csv', index = "none", header="true")
