Excel Tool That Downloads & Displays Wordpress Stats API Data

I need an Excel user defined function that pulls in data from the Wordpress Stats API ([login to view URL]) and displays it in Excel. The input variables should be the user's api_key, blog_uri & period, which can be defined in a cell on the spreadsheet. The user should be able to enter multiple blog_uri's and display stats for all blogs over the available date range. The data should be visible by day, week or month, depending on the variable selected for "period". I'm not sure if there's a way to do this, but if it is possible to pull all blog_uri's associated with a user without having to enter them as values, that should also be an option. Authentication is required. The tool should authenticate to a mySQL database in order to work. In other words, someone shouldn't just be able open up the excel doc, manipulate it and get it to work without an OK from my database.
