Google Sheets API with Python

Question

I am attempting to connect to this Google Sheet: https://docs.google.com/spreadsheets/d/1u3Ql_Rs19PEe0mwqpsiw2wf2cUEbnSG4vZL63rh_OaE/edit?usp=sharing

Both the .json file and the .py file are saved to my desktop.

The email in the .json has been shared with the Google Sheet

I am getting a 'JSONDecodeError: Expecting value' and cannot figure out why.

I have revised the client id and key info in the .json for pirvacy as I am new to this and was not sure if sharing this was wise

Any help is greatly appreciated. thank you

python:

import gspread

gc = gspread.service_account(filename = 'credentials.json')

sh = gc.open('User')

worksheet=sh.sheet1

res=worksheet.get_all_records()

print(res)

credentials.json:

{
  "type": "service_account",
  "project_id": "clear-heaven-331616",
  "private_key_id": "abcxyz",
  "private_key": "-----BEGIN PRIVATE KEY-----\abcxyz=\n-----END PRIVATE KEY-----\n",
  "client_email": "[email protected]",
  "client_id": "abcxyz",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",

  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/my-service-account%40clear-heaven-331616.iam.gserviceaccount.com"
}

JSONDecodeError: Expecting value

what line are you getting the error on? paste in the full stacktrace. Also, have you tried using open_by_key instead? — howMuchCheeseIsTooMuchCheese

I did try the open_by_key and had the same result. I have updated the post to show the traceback (I believe this is what you were after? new to this...). — ah2Bwise

First off I would double check that you created service account credentials on google cloud console.

Then I would consider using the Google-api-Python-client library this is googles official client library.

Then you should consider using from_json_keyfile_name

"""Hello Sheets API V4."""

from apiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials


SCOPES = ['https://www.googleapis.com/auth/drive']
KEY_FILE_LOCATION = '<REPLACE_WITH_JSON_FILE>'
VIEW_ID = '<REPLACE_WITH_VIEW_ID>'


def initialize_sheets():
  """Initializes an sheets API V4 service object.

  Returns:
    An authorized sheets API V4 service object.
  """
  credentials = ServiceAccountCredentials.from_json_keyfile_name(
      KEY_FILE_LOCATION, SCOPES)

  # Build the service object.
  sheets = build('sheets', 'v4', credentials=credentials)

  return sheets
