Offering to maintain sheets

Thanks for the request. This module is meant to host the base code for the Commerce Sheets → module. That module was started for Commerce Drupal applications, but ended up providing a generic mechanism for importing/exports spreadsheets. After some clean up, the code will therefore here as Sheets to offer a more generic solution. I expect that to be done at some point this year, at which point I will update this module's page.

What you propose does not fit here, it seems that it is more specific to Google spreadsheets and you may want to talk with the maintainer of the Google Sheets module.
