Should I build an army of Google Sheets data add-ons?

I have a MVP I am working on right now that will allow an Etsy Seller to link their store(s) and import their shop data directly into Google Sheets for accounting and management.

I am not sure if it will work out, but I got to thinking: I could probably reuse 80% of the code and basic framework to import all kinds of data into Google Sheets. The set up would be as follows:

• Landing page and payment portal
• Basic app frontend for linking accounts and authenticating APIs
• Serverless backend to handle the data fetching and manipulation
• Google Sheets add-on to pull data from the backend
• Google Sheets starter template for working with the data

To me the possibilities are really endless as far as what could be pulled in. From Etsy to Shopify to Twitter analytics.

I would love to get feedback from the community on this. Do you think there is something here? Any ideas of useful data that you would want in Google Sheets automatically? All feedback is welcome!
