It sounds like what you'll wan to do is make a HTTP request a remote server to send your data. I don't know enough about Godot to tell you how to specifically do it. Trying to do it with a bat or vbs file probably isn't the best idea, it might be picked up by a virus scanner as being suspicious.

I know avast doesn't detect it as such. Windows defender flags it when you open the bat directly but when the vbs opens the bat it doesn't have a problem with it. As for HTTP I have tried it somewhat but it confuses me. Also part of the reason I am attempting to do this through google scripts is due to the infinite space I get as long as it is in a google format. Although I think I might have been attempting to use the http client rather then request. Here is the documentation on both if you are curious http://docs.godotengine.org/en/2.1/classes/class_httpclient.html , http://docs.godotengine.org/en/2.1/classes/class_httprequest.html .
