如何使用循环从JSON提取多个数据以创建CSV

Question

如何使用for从JSON中提取name和value并将所有数据输入CSV中？

我希望从代码中得到CSV中的名称和值列表。喜欢：

代码：

        if valueselector == 'PRINT':
           idMag = json_dict['data']['archivingLegal']['idMag']
           roomid = json_dict['data']['archivingLegal']['roomid']
           safeid = json_dict['data']['archivingLegal']['safeid']
           serieID = json_dict['data']['archivingLegal']['serieID']
           serieCode = json_dict['data']['archivingLegal']['serieCode']
           fdr = json_dict['data']['archivingLegal']['fdr']
           createSafe = json_dict['data']['archivingLegal']['createSafe']
           fromGif = json_dict['data']['archivingLegal']['fromGif']
           indexFileName = json_dict['data']['archivingLegal']['indexFileName']
           originalName = json_dict['data']['archivingLegal']['originalName']
           xmlns = json_dict['data']['archivingLegal']['archives']['-xmlns']
           for i in range(0, 8):
               indexName = json_dict['data']['archivingLegal']['archives']['archive']['index'][i]['name']
               indexValue = json_dict['data']['archivingLegal']['archives']['archive']['index'][i]['value']
           recordId = json_dict['data']['archivingLegal']['dataMode']['recordId']
           raw_data_archivingLegal = [idMag, roomid, safeid,
                                      serieID, serieCode, fdr,
                                      createSafe, fromGif, indexFileName,
                                      originalName, xmlns, indexName,
                                      indexValue, recordId, '',
                                      '', '', '',
                                      '', '', '']

我的DataFrame配置索引：

"----": ['idMag', 'roomid', 'safeid',
         'serieID', 'serieCode', 'fdr',
         'createSafe', 'fromGif', 'indexFileName',
         'originalName', 'xmlns', 'indexName',
         'indexValue', 'recordId', '',
         '', '', '',
         '', '', ''],
"archivingLegal": raw_data_archivingLegal,

JSON：

            }
        },
        "createSafe": " ",

我的实际输出csv：

将它们迭代到列表中。然后，您可以保留为列表，或将值连接到单个字符串中（如预期输出所示：

json数据

json_dict = {"data": {
    "archivingLegal": {
        "archives": {
            "-xmlns": "google.com",
            "archive": {
                "index": [{
                        "name": "FILENAME",
                        "value": " "
                    }, {
                        "name": "TYPEDOC",
                        "value": " "
                    }, {
                        "name": "ORGANISATION",
                        "value": " "
