将数据帧解析为 Google API 时出错

Question

我想执行一项日常工作，将数据框解析为 Google 表格。 代码从第一个空行开始进入 Google 工作表并添加数据。 我有两个案例。如果我以 json 格式上传数据，它可以工作，但它是 1 行数据，不可读。我希望格式为数据框，但如果我从代码中删除语句BTCJPY = BTCJPY.to_json()，则会出现以下错误：

  File "test_cmc.py", line 121, in <module>
worksheet.update_acell("A{}".format(next_row), BTCJPY)
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/gspread/models.py", line 715, in update_acell

TypeError: Object of type DataFrame is not JSON serializable

我的代码：

def next_available_row(worksheet):
    str_list = list(filter(None, worksheet.col_values(1))) 
    return str(len(str_list)+1)

scope = ["https://spreadsheets.google.com/feeds",'https://www.googleapis.com/auth/spreadsheets',"https://www.googleapis.com/auth/drive.file","https://www.googleapis.com/auth/drive"]
os.chdir(sys.path[0])
creds = ServiceAccountCredentials.from_json_keyfile_name("client_secret1.json", scope)
client = gspread.authorize(creds)
sheet = client.open("Market_data")
worksheet = sheet.worksheet('BTCJPY')
next_row = next_available_row(worksheet)

###GET THE BTC JPY###
url = 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/ohlcv/historical'
parameters = {
  'symbol':'BTC',
  'count':'90',
  'interval':'daily',
  'convert':'JPY'
}
headers = {
  'Accepts': 'application/json',
  'X-CMC_PRO_API_KEY': 'XXXXXXXXXXXXXXXXXXXXXXXXXX',
}
    session = Session()
session.headers.update(headers)
response = session.get(url, params=parameters)
data = json.loads(response.text)
used_list = [
    item['quote']['JPY']
    for item in  data['data']['quotes']
]
BTCJPY = pd.DataFrame.from_records(used_list)
BTCJPY = BTCJPY.set_index('timestamp')
spread = Spread(creds, 'Market_data')
BTCJPY = BTCJPY.to_json()
worksheet.update_acell("A{}".format(next_row), BTCJPY)

Answer 1

此代码删除错误是：

spread = Spread(creds, 'Market_data')
spread.df_to_sheet(df= BTCJPY, headers= False, start= "A{}".format(next_row), sheet= 'BTCJPY', replace= False, freeze_headers= False)

代替：

worksheet.update_acell("A{}".format(next_row), BTCJPY)
