In this tutorial, I'll show you how to set up a Google Form and use Google App Scripts to store results directly to a CartoDB. As a bonus, we also will use a function to geocode location data using the Google service.
In the end we will have:
A form: docs.google.com/forms/d/1KmHy6EBmwdBHrPHfIvRiZgwZxVNj7_fjSk6Um2EHENM/viewform
A map: bl.ocks.org/andrewxhill/raw/5579335/
