Most of the clients are very used to an "Excel" like interact for their backend. I am not using excel per se, but using excel to manipulate data and seamlessly push the changes to e-commerce. So the user uses google docs and all its rich UI to manipulate data very quickly and with the click of a button (inside google spreadsheet) the data gets pushed to the ecommerce (after validation). The status of each update is then pushed back to the spreadshet. The goal here is to let users use their familiar UI for managing their e-commerce backend. It was my mistake to say that I am using excel as the backend. The correct phrase is that I am using the google spreadsheet as the data manipulation UI for ecommerce and then sync-ing it to the ecommerce backend.
