将 Json 转换为 CSV

Question

我有 json 这种格式，想转换成 CSV 文件。

{
  "extrapolationLevel": 1,
  "columnNames": [
    "name",
    "usersession.country",
    "application",
    "usersession.osFamily",
    "usersession.startTime",
    "visuallyCompleteTime"
  ],
  "values": [
    [
      "pdp",
      "Serbia",
      "Desktop",
      "Windows",
      1573215462076,
      1503
    ],

  ]
}

我想将这个 json 转换成 CSV 格式这是我的脚本

import csv
import json

with open('response_1573222394875.json') as infile:
    Data = json.loads(infile.read())

with open("q.csv", "w") as outfile:
    f = csv.writer(outfile)
    f.writerow(["name","usersession.country","application","usersession.osFamily","usersession.startTime","visuallyCompleteTime"])
    f.writerow([Data["name"], Data["usersession.country"],
                Data["application"],
                Data["usersession.osFamily"],
                Data["usersession.startTime"],
                Data["visuallyCompleteTime"]])

预期输出

 name usersession.country application usersession.osFamilyusersession.startTime visuallyCompleteTime
      pdp      Serbia      Desktop      Windows      1573215462076      1503

    startpage  uk            Site         Windows      1573215462076      1639

       pdp     Vietnam      APP         Windows        1573215462076      3299

谁能帮帮我。

Answer 1

Data的键是"extrapolationLevel"、"columnNames"、"values"，没有别的。 Data["usersession.country"]，例如，没有意义，因为不存在带有该键的字典。这些值只是存储在列表中。以下是您需要做的所有事情：

with open("q.csv", "w") as outfile:
    f = csv.writer(outfile)
    f.writerow(Data["columnNames"])
    f.writerows(Data["values"])

Answer 2

import json

json_str = '''
{
  "extrapolationLevel": 1,
  "columnNames": [
    "name",
    "usersession.country",
    "application",
    "usersession.osFamily",
    "usersession.startTime",
    "visuallyCompleteTime"
  ],
  "values": [
    [
      "pdp",
      "Serbia",
      "Desktop",
      "Windows",
      1573215462076,
      1503
    ]
  ]
}
'''

data = json.loads(json_str)

csv_row = lambda v: ('"{}",' * len(v)).format(*v)[:-1] # remove trailing comma

print(csv_row(data["columnNames"]))
for value in data["values"]:
    print(csv_row(value))
