提前感谢。您的数据中缺少字段，如果有，我建议使用
。获取词典的选项
诸如此类
jsonfile = open('data.json', 'r').read()
csvfile = open('data.csv', 'w', newline='')
rows = json.loads(jsonfile)
output = []
for row in rows:
outrow = [row.get('name'),
row.get('title'),
row.get('emails'),
row.get('updateTime'),
row.get('roles')]
output.append(outrow)
writer = csv.writer(csvfile)
writer.writerows(output)
对于放置整数的版本，您在之前缺少了一个]谢谢您的评论。我的坏消息我错过了它，我更新了它，现在它给出了以下错误------------------------------------------------------------------->13 csv_文件。writerow（[item['name'，item['title'，item['emails'，item['updateTime'，item['roles'][1] ]）索引器错误：列表索引超出范围更新您的问题-可能对于此条目item['roles']
只有一个条目，即索引0。最初我尝试使用item['roles']但在这种情况下，所有与角色相关的值都会出现，因此认为应该使用索引来更新它，但使用索引0时，它也会给出索引超出范围的错误。也许角色是一个空列表-IDK您必须检查它-这是您的数据！
