I have made a small example on how you easily can do it
here is a link to a google sheet
and here is a link to a bss design
so you can see how it works open the two links and fill in name country website and email in the google sheet and then refresh the bss design and what you wrote will show up in the table you can download the bss design and see how I made it.
step 1 go to your google sheet make a new sheet
step 2 Publish it on the web
step 3 Share it public or everybody with the link. Your link will look something like this https://docs.google.com/spreadsheets/d/1mSFfX6l5PThhdbimE4cUg6jXQ10J1faqlQYDJsB0lUw/edit#gid=0
copy the id part of the link and paste it in the untiled.js
have fun and stay safe
