在 python3 中将 JSON 转换为 CSV

Question

我有一个 JSONObject 需要与标题一起写入 CSV 文件。

我的错误：

` File "/usr/local/Cellar/python/3.7.5/Frameworks/Python.framework/Versions/3.7/lib/python3.7/json/__init__.py", line 341, in loads
    raise TypeError(f'the JSON object must be str, bytes or bytearray, '
TypeError: the JSON object must be str, bytes or bytearray, not list`

我的 JSONObject（更新记录）：

[
      "{\"name\": \"Anu Ghosh\", \"email\": \"abcd@gmail.com\", \"mobile_number\": \"99999999\", \"skills\": [\"Recruitment\", \"International\", \"Coding\", \"Wifi\", \"Programming\", \"Training\", \"Mobile\", \"Sourcing\", \"Email\", \"English\", \"Design\", \"Electronics\", \"System\", \"Strategy\", \"Content\", \"Scheduling\", \"Technical\", \"Hardware\", \"Lighting\", \"C\"], \"college_name\": null, \"degree\": [\"Bachelor of Technology in \\nElectronics and \\nTelecommunication(B.Tech)\"], \"designation\": [\"Internet of Things (IOT)\"], \"experience\": \"1\", \"company_names\": null, \"no_of_pages\": 2, \"total_experience\": 0, \"fullName\": \"Anu Ghosh\", \"emailId\": \"abcd@gmail.com\", \"phoneNumber\": \"23454654434\", \"currentLocation\": \"Mumbai\", \"closestCity\": \"Mumbai\", \"resumeLink\": \"/Users/abc/Downloads/aaa.pdf\", \"applicationJobCode\": \"DEF\", \"applicationJobTitle\": \"HR\"}",
      "{\"name\": \"Prakash\", \"email\": \"sdsn@gmail.com\", \"mobile_number\": \"+99877678888\", \"skills\": [\"Scala\", \"Google drive\", \"Database\", \"Rest\", \"Communication\", \"Zookeeper\", \"Programming\", \"Sql\", \"Python\", \"Agile\", \"Javascript\", \"Mobile\", \"Mysql\", \"Json\", \"Compliance\", \"Hotels\", \"Fabric\", \"Architecture\", \"Api\", \"Requests\", \"Reporting\", \"Operations\", \"Pycharm\", \"Troubleshooting\", \"Html\", \"Ui\", \"Video\", \"C++\", \"English\", \"Gap analysis\", \"Java\", \"Cloud\", \"Design\", \"Windows\", \"Visual\", \"Click\", \"Oracle\", \"Jira\", \"Scrum\", \"System\", \"Hadoop\", \"Security\", \"Schedules\", \"Ibm\", \"Spark\", \"Analysis\", \"Linux\", \"Project planning\", \"Intranet\", \"Postgresql\", \"Css\", \"Process\", \"Software development life cycle\", \"Technical\", \"Js\", \"Aws\", \"Sdlc\", \"C\", \"Certification\", \"Test cases\"], \"college_name\": null, \"degree\": [\"M.S (IT)\"], \"designation\": null, \"experience\": \"4\", \"company_names\": [\"Oracle\"], \"no_of_pages\": 7, \"total_experience\": 0.0, \"fullName\": \" prakash\", \"emailId\": \"bbbb@gmail.com\", \"phoneNumber\": \"99998898998\", \"currentLocation\": \"Mumbai\", \"closestCity\": \"Mumbai\", \"resumeLink\": \"/Users/abc/Downloads/v_cv.pdf\", \"applicationJobCode\": \"ABVC\", \"applicationJobTitle\": \"Developer\"}"
]

我写了这个不起作用的代码块。

def writeToCSV(updatedDBRecord):
record = json.dumps(updatedDBRecord)
record = json.loads(record)
f = csv.writer(open('/Users/varunprakash/Documents/candidate.csv','w'))
f.writerow(['Name','EmailId','PhoneNumber','Experience','Skill','CurrentLocation','ClosestCity','ResumeLink','ApplicationJobCode','ApplicationJobTitle'])
for data in record:
    print(data)
    f.writerow(data['fullName'],data['emailId'],data['phoneNumber'],data['experience'],data['skill'],data['currentLocation'],data['closestCity'],data['resumeLink'],data['applicationJobCode'],data['applicationJobTitle'])
f.close()

任何想法表示赞赏。

Answer 1

一开始你搞砸了负载和转储，但你的逻辑是合理的。

import csv
import json
from pprint import pprint

def writeToCSV(updatedDBRecord):
    for data in updatedDBRecord: 
        record = json.loads(data)
        with open(r'c:\tmp\tmp.csv','w') as fp:
            f = csv.writer(fp)
            f.writerow(['Name','EmailId','PhoneNumber','Experience','Skills','CurrentLocation','ClosestCity','ResumeLink','ApplicationJobCode','ApplicationJobTitle'])
            f.writerow([record['fullName'],record['emailId'],record['phoneNumber'],record['experience'],record['skills'],record['currentLocation'],record['closestCity'],record['resumeLink'],record['applicationJobCode'],record['applicationJobTitle']])

data = [
      "{\"name\": \"Anu Ghosh\", \"email\": \"abcd@gmail.com\", \"mobile_number\": \"99999999\", \"skills\": [\"Recruitment\", \"International\", \"Coding\", \"Wifi\", \"Programming\", \"Training\", \"Mobile\", \"Sourcing\", \"Email\", \"English\", \"Design\", \"Electronics\", \"System\", \"Strategy\", \"Content\", \"Scheduling\", \"Technical\", \"Hardware\", \"Lighting\", \"C\"], \"college_name\": null, \"degree\": [\"Bachelor of Technology in \\nElectronics and \\nTelecommunication(B.Tech)\"], \"designation\": [\"Internet of Things (IOT)\"], \"experience\": \"1\", \"company_names\": null, \"no_of_pages\": 2, \"total_experience\": 0, \"fullName\": \"Anu Ghosh\", \"emailId\": \"abcd@gmail.com\", \"phoneNumber\": \"23454654434\", \"currentLocation\": \"Mumbai\", \"closestCity\": \"Mumbai\", \"resumeLink\": \"/Users/abc/Downloads/aaa.pdf\", \"applicationJobCode\": \"DEF\", \"applicationJobTitle\": \"HR\"}",
      "{\"name\": \"Prakash\", \"email\": \"sdsn@gmail.com\", \"mobile_number\": \"+99877678888\", \"skills\": [\"Scala\", \"Google drive\", \"Database\", \"Rest\", \"Communication\", \"Zookeeper\", \"Programming\", \"Sql\", \"Python\", \"Agile\", \"Javascript\", \"Mobile\", \"Mysql\", \"Json\", \"Compliance\", \"Hotels\", \"Fabric\", \"Architecture\", \"Api\", \"Requests\", \"Reporting\", \"Operations\", \"Pycharm\", \"Troubleshooting\", \"Html\", \"Ui\", \"Video\", \"C++\", \"English\", \"Gap analysis\", \"Java\", \"Cloud\", \"Design\", \"Windows\", \"Visual\", \"Click\", \"Oracle\", \"Jira\", \"Scrum\", \"System\", \"Hadoop\", \"Security\", \"Schedules\", \"Ibm\", \"Spark\", \"Analysis\", \"Linux\", \"Project planning\", \"Intranet\", \"Postgresql\", \"Css\", \"Process\", \"Software development life cycle\", \"Technical\", \"Js\", \"Aws\", \"Sdlc\", \"C\", \"Certification\", \"Test cases\"], \"college_name\": null, \"degree\": [\"M.S (IT)\"], \"designation\": null, \"experience\": \"4\", \"company_names\": [\"Oracle\"], \"no_of_pages\": 7, \"total_experience\": 0.0, \"fullName\": \" prakash\", \"emailId\": \"bbbb@gmail.com\", \"phoneNumber\": \"99998898998\", \"currentLocation\": \"Mumbai\", \"closestCity\": \"Mumbai\", \"resumeLink\": \"/Users/abc/Downloads/v_cv.pdf\", \"applicationJobCode\": \"ABVC\", \"applicationJobTitle\": \"Developer\"}"
]

writeToCSV(data)

这按预期工作。

Answer 2

json 格式不正确。

样品 json：

[
 {"name": "Anu Ghosh", "email": "abcd@gmail.com"},
 {"name": "Prakash", "email": "sdsn@gmail.com"}
]
