We have been working with some customers needing to update Google sheets directly from emails that come in (payment confirmations) and other applications. This has been great as we had not done a lot of work in Google Sheets so this was a nice dive into Google sheets.
This particular application was when customers received payments from Stripe.com payment processor, we automated updating payments into Google sheets so they were able to see who has paid and who has not. This was a faily simple application and we will be doing a lot more deep dives into automating Google sheets since it is wildly popular.
