Open documents, ppt and excel sheets directly into google docs/driver

I do not want to use libreoffice and not able to find lightweight alternative for excel and ppt viewers.

So could you please tell me how can trick nautilus to open these files directly into google docs/drive using my default browser.

nautilus-gdoc seems to add this functionality, but it can not open it seemlessly. i.e. double clicking does not take me to browser and open the document.
