My seriously awesome Google Sheet has 2 user-defined functions. One for bringing in a lot of stock data...

...and one for filtering/sorting that data to find "good" stocks.

To accomplish this feat, I use Google Apps Script...

...a MySQL database...

...Flask, SQLAlchemy, some webscraping (with BeautifulSoup), an API endpoint that returns a csv representation of the data...

...and some more Flask.
