I spent some time to google it, but have not found an answer.
Installed Goggle drive locally, but there are only links (1K-size) to real docs and sheets.
If I drag'n'drop that link (in example lhnet.gsheet) into alfresco document library, alfresco can't identify it as google sheet.
But there was no solution.
I tried https://community.alfresco.com/thread/214692-alfresco-chrome-extension-to-upload-files but could not specify the directory:)
Than I found 2 things: 1) https://github.com/Alfresco/google-docs/tree/V3.0.3 and
And which one of that and how could I use to place my existing google doc into alfresco?
