I didn't want to have my own server..
I think it is possible with this.
developers.google.com/sheets/api/guides/batchupdate
But I don't understand how to do and what to do..My programming knowledge is very low. I don't know how to integrate this with my construct 3 project.
I don't understand most of the things advanced topics in Construct 3.
Well these are out of my scope I s'pose.
