Step 5: Share Google Sheets with Service Account

• Go to your Google Drive and create a new Google Sheet. Name the spreadsheet Redshift-to-Google-Sheet or any other suitable name.
  
• Open the client_secretkey.json file and copy the value of the client_email field. Share the Google Sheet with this client_email with edit permissions so the service account can write data to it.

Step 6: Install Required Libraries

• At this point, you have set up the necessary credentials and shared the Google Sheet with the service account. Now you can write your Python script to extract data from Amazon Redshift and push it to Google Sheets.
  
• Open the terminal and run the following commands to install the necessary Python libraries:

python
pip install gspread
pip install oauth2client
pip install sqlalchemy
pip install df2gspread

Step 7: Create Python Script

• Create a new Python file and name it redshift_to_spreadsheet.py. Copy and paste the following code into the script:

python
import gspread
from oauth2client.service_account import ServiceAccountCredentials
import pandas as pd
from sqlalchemy import create_engine
from df2gspread import df2gspread as d2g
 
# Set the scope for Google Sheets API
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"]
 
# Upload the DataFrame to the specified Google Spreadsheet
def write_googlesheet(df, spreadsheet_key, sheet_title, starting_cell, overwrite):
d2g.upload(df, spreadsheet_key, sheet_title, credentials=credentials, col_names=overwrite, row_names=True, start_cell = starting_cell, clean=overwrite)
 
if __name__ == "__main__":
# Connecting to the Amazon Redshift database
engine = create_engine('postgresql://user:password@host:5439/database')
data_frame = pd.read_sql('SELECT * FROM article_sales;', engine)
print(data_frame)
credentials = ServiceAccountCredentials.from_json_keyfile_name('client_secretkey.json', scope)
client = gspread.authorize(credentials)
            write_googlesheet(data_frame, 'SPREADSHEET_KEY', 'Sheet1', 'A1', True)

• Replace the details such as client_secretkey.json, user:password@host:5439/database, SELECT * FROM article_sales, and SPREADSHEET_KEY with your respective actual values for service account credentials, Amazon Redshift database connection, SQL query, and Google Spreadsheet key.

Step 8: Run the Script

• Run the Python script. Now, Open the Google Sheet you specified with the spreadsheet key. You will see that your Google Sheet is updated with the content fetched from Amazon Redshift.

Limitations of Using Python Scripts 

There are, however, a few downsides to using Python scripts to move data from Redshift to Google Sheets: 

• Technical expertise: This method requires technical expertise in Python programming, making it challenging for non-technical users to implement and maintain the script due to complexities in understanding Python concepts, libraries, APIs, and managing dependencies.
  
• Real-Time Updates: This method does not offer real-time updates to the Google Sheet, meaning that the data in the Google Sheet will not automatically reflect changes made in the Redshift database after the initial run of the script. Nevertheless, you can set up real-time updates but that would require more technical expertise. 
  
• Maintenance and Error Handling: The script may require additional error handling and maintenance, as any changes in the database schema or API behavior could lead to errors or inconsistencies in the data extraction process, requiring periodic updates and monitoring.
