Writing .gdoc files from a web browser

.gdoc files are converted to Word but the format is very simple

{"url": "**URL**", "resource_id": "document: **ID**" }

in which the URL contains the ID:

https://docs.google.com/document/d/**ID**/edit?usp=docslist_api

thus the files can be written knowing just the ID ($ID):

{"url": "https://docs.google.com/document/d/`$ID`/edit?usp=docslist_api", "resource_id": "document: `$ID`" }
