Script for repeated automated data import

I need a script that imports data at the end of each day (23:59 central european time) and puts it into a spreadsheet. This can be Excel or Google Spreadsheet (Each day into a new sheet). The source of the data can be found here: [login to view URL] The page behaves a bit special, because once it is past midnight, the page for the new day sets up and there is no archive function. So with the standard import functions of excel and google you would lose the data. So the script has to maneuvre around that and save every day into a new sheet.
