誰かがこのコードを送って、json から csv 形式に変換しました。
json2csv のコードは次のとおりです。
import sys, json, csv
input = open(sys.argv[1])
json_array = json.load(input)
input.close()
item_data = json_array
if len(item_data) >= 1:
first_item_id = item_data[0]['item_id']
columns = item_data[0].keys()
csv_file = open(sys.argv[2], "wb")
writer = csv.writer(csv_file)
# there is currently a known bug where column names are partially uppercase, this will be fixed soon. the "map(lambda x: x.lower(), columns)" fixes this issue in the mean time
writer.writerow(map(lambda x: x.lower(), columns))
# here .items() is a standard python function
for item in item_data:
row = []
for column_name in columns:
if column_name.lower() == 'name_part': # lower required due to above issue
row.append(" ".join(item[column_name]))
else:
row.append(item[column_name])
writer.writerow(row)
これが私のjsonデータです。これをtransaction.jsonとして保存しました

私はやってc:\python.exe c:\json2csv.py c:\transaction.json c:\transaction.txt
みましたが、エラーが発生しました
Extra data line2 column 1 - line 12 column1 (char 1105 - char 11267)
誰かがすべてのフィールドを取得するようにコードを修正できれば、それは素晴らしいことです。私はcsvのすべてのフィールドさえ必要としません。client_external_id
, invoice_clinician_id
, invoice_id
, , location
i tem_name
, item_unit_price
, item_description
,だけが必要です。quantity
billing_date
これは長い間保留されていました。今日これを完了する必要があります。助けてください。
