Android tablet spreadsheet editor: Google Docs (Google Drive)
Google Docs offers very limited spreadsheet editing capabilities. First and foremost, only spreadsheets saved in Google Docs format will open in the app, rendering it useless for editing of any desktop-created documents.

More advanced features like text formatting, calculations, and multiple worksheet toggling are all missing in action.
