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": "my-service-account@clear-heaven.iam.gserviceaccount.com",
  "client_id": "abcxyz",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",

}

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
