I am wondering if its possible for me to connect my form from google forms to the wix database?
I dont think so. Has to be wix forms.
There is no builtin feature.
The only thing you can do that is easy is to create an account at Zapier and hook that to your Google Form Submissions and then use ACTION Webhook to POST the results to http-functions.js file and a function in that from Zapier and then use wixData.insert your data into your Wix Data Collections.
Way easier to just make a form on a page in Wix and connect it to a Dataset with Write Only settings and voila, done.
