无法使用python将完整的json转换为正确的csv

Question

我正在使用python将复杂的json转换为csv

              I want to convert complex json into csv using python      
               sample json :
                {
                    "data":[
               {
           "filter":"tags",
            "cost":1234,
          "values":[
           {
          "count":13,
         "subvalues":[
            {
              "count":1,
             "subvalue":"goat",
             "cost":227.576
             },
              "storage":[
                {
            "resource_id":"1234343413",
          "cost":25.047,
             "running_hours %":61.52777777777778,
           "created_in":"asd ",
             "account_name":null,
                "service":"csdsae",
                etcc...

我编写的代码如下：                我的python代码：

                        import json
                       import csv

                  f = open('file.json')

                 data = json.load(f)
                s=csv.writer(open('test6.csv','w'))
               count = 0
                for item in data["breakdown"]:
              s.writerow([item])

                if count == 0:
                    header = item.keys()

                    s.writerow(header)

                    count += 1

                    s.writerow(item.values())

但是我没有在csv文件中获得正确的输出只获得一行但完整的json不会出现
