Without worrying about HOW it will be implemented, can you describe in words, what you would like to achieve by linking spreadsheets with a mobile friendly interface and what would be the benefit to users?
Example:
First I want the user to select a customer from a database then select stock items from another database, add volume to quote on. OR
I need my remote workers to complete a time sheet based on the work they have completed and when.
OR I'd like my prospective clients to tell me what they are interested in / buying or attending an event or completing a survey on any device.
