Is it possible to use quip as data base ?
quip? not directly. You can use S3 and a Lambda function with Python to pull data from Quip and serve it to Quicksight.
To extract data from Quip, do a google search for Python and Quip integration. There is an API that can help.
Once you pull the data from Quip (either running the script on your local machine or using a Lambda function to run the Python code) save it in S3 and connect Quicksight to S3.
Hope it helps,
