I solved a problem in my workplace. As in, people were bookings rooms using a book. So I made a booking system. Have a think about problems people are solving with spreadsheets. This may give you some ideas. Also consider integrations. For example, I have another product which exports timetable data from spreadsheets to Google Calendar. Why are people putting timetable data in spreadsheets? That's not the problem I am getting paid to solve :-)
