Tutorial: How to Retrieve Data from Google Sheets and Insert It into PostgreSQL Using Python

In this blog post, I will explain step-by-step how to retrieve data from Google Sheets, set it up on Google Cloud, and use Python to insert the data into a PostgreSQL database. This process is useful for automating the transfer of data from Google Sheets to your database for further analysis and processing.

I have used this script on several occasions, with few columns, few records and also with many columns and many records, so I can assure you that it works.

Step 1: Create and Set Up Your Google Sheet

First, create a spreadsheet in Google Sheets with the following column structure: Concept, Quantity, Amount, Date and Category

Step 2: Set Up the Google Sheets API in Google Cloud

Create a New Project:

• Go to Google Cloud Console.
• Click on the project dropdown and select “New Project”.
• Name your project and click “Create”.

Enable the Google Sheets API:

• In the Google Cloud Console, navigate to the “APIs & Services” > “Library”.
