Google Sheets can act as a database for your app; you can send data to a Sheet, or pull data from a Sheet into your app. The Google Sheets integration requires a Standard subscription.
By default, sending data to Google Sheets will create a new row. You can also update an existing row. Also, if you're sending a lot of data, you can skip the task of manually specifying what data to send over and just send all data that matches your google column headers.
