Converting .gdoc files to .docx format.
It is not possible to directly to convert Google Docs Shortcuts to Microsoft Word Documents (.gdoc to .docx conversion), since .gdoc files only contain references to documents it is meant to open, as well as the appropriate Gmail account link to the document.
You can, however, use the .gdoc link to open the actual Google Document, and then download it to MS Word format, in this case, .docx.
There are no online converters capable of converting .gdoc to .docx.
