Python 从 JSON 转换为 CSV 时出现 3 个编码问题

Question

Python3

我看过其他解决方案，但他们似乎没有涵盖我的情况。我负责编写脚本以获取 JSON 并将其转换为 CSV 文件。

我已经完成了大部分工作，但在写入数据时遇到了问题。我收到的数据与写入的不符。下面是一个例子。我不知道如何才能保留编码。

我应该提到默认编码是 UTF-8

输入：necesitará

输出：necesitar×

import csv
import json
import sys
import sys
print(sys.getdefaultencoding())
stuff = open('data.json')

jsonStuff = json.loads(stuff.read(), encoding="utf-8")
with open('output.csv', 'w', newline='\n', encoding='utf-8') as csvfile:
    writer = csv.writer(csvfile, delimiter=",",quotechar='"',quoting=csv.QUOTE_MINIMAL)

    for element in jsonStuff:
        row = ""
        key = element['key']
        values = element['valuesRow']

        row = element['key']
        # values[0]['value'], values[1]['value'], values[2]['value'], values[3]['value'],

        writer.writerow([element['key'], values[3]['value']])

Answer 1

删除 open('output.csv', 'w', newline='\n', encoding='utf-8') 中的 encoding='utf-8' 应该可以修复它。

data.json (utf-8): {"first": "necesitará", "second": "bodø"}

以下...

import csv
import json

with open('data.json') as stuff, open('output.csv', 'w', newline='\n', encoding='utf-8') as csvfile:
    jsonStuff = json.loads(stuff.read(), encoding="utf-8")
    writer = csv.writer(csvfile, delimiter=",", quotechar='"', quoting=csv.QUOTE_MINIMAL)
    first = jsonStuff['first']
    second = jsonStuff['second']
    writer.writerow([first, second])

... 给出 output.csv: necesitarÃ¡,bodÃ¸

然而...

import csv
import json

with open('data.json') as stuff, open('output.csv', 'w', newline='\n') as csvfile:
    jsonStuff = json.loads(stuff.read(), encoding="utf-8")
    writer = csv.writer(csvfile, delimiter=",", quotechar='"', quoting=csv.QUOTE_MINIMAL)
    first = jsonStuff['first']
    second = jsonStuff['second']
    writer.writerow([first, second])

... 产生 output.csv：necesitará,bodø

话虽如此。当您有 json.load() 时，没有理由使用 json.loads()，并且您定义的大部分内容都是默认值。我只是做...

import csv
import json

with open('data.json') as jsonfile, open('output.csv', 'w') as csvfile:
    json_data = json.load(jsonfile)
    writer = csv.writer(csvfile, quoting=csv.QUOTE_MINIMAL)
    first = json_data['first']
    second = json_data['second']
    writer.writerow([first, second])
