Here are some things you might want to try.
There are plenty of open source readers for excel. You can try the Java API
http://www.andykhan.com/jexcelapi/index.html. There are php readers out there that work a little better with databases and webservers, but you might need to do some digging to find them.
As for working with seperate sheets, you might want to consolidate them all into one book. This way when you hit save you save all ten sheets at once.
Once you get a reader working, all you then need to do is make a script or a file you can run from the command file that handles the connection from the webserver to the database.
