IIRC the Drive API does not support those conversion options. The way forward would be for an xlsx parsing JS library to convert it into CSV or a stream of Javascript objects. I didn't find any GPL-compatible library last time I checked.

See https://developers.google.com/drive/web/manage-downloads for a list of export format possibilities. For spreadsheets, the only options are xlsx, odt and pdf.

Google Drive document can be embedded as iframes. Wouldn't this solve this problem?

Here's a proof: http://www.cellmaster.com.au/example.html

not for retrieving the juicy data inside the spreadsheet as objects.

Oh, I didn't read the whole thread, I was just thinking about my own experience with `cat gdrive/something` showing me a lot of unreadable bytes when it could show an iframe.
