Import or feed Google Sheets data to automatically update Squarespace page's fields (i.e., title, etc.)

Is there a way to upload/import/feed in data from Google Sheets to a Squarespace website so that certain fields are automatically updated?  (fields like title, home page image, etc.) Basically I want to enable a "demo" website for clients or myself to easily enter information and have the website populate with the updated data so clients can see in either real-time (or at least cut my manual entering time down) their customized web page. 

There is no automatically way, you got to use javascript to achieve
