How to pull cell data from Excel Online into Swift application

I have an Excel Online spreadsheet that is embedded on a webpage using http://ift.tt/1E18RaS. It is updated throughout the day.

I want to create a simple Swift application that pulls a number from a particular cell on that spreadsheet and displays it in the Swift app.

That's it.

I have read been reading previously posted questions and I'm confused if I should be reading up on how to use ODBC, Jquery, XML parsing, CSV parsing, NSString url parameters, etc. I'm a n00b and I need to be pointed in the right direction.

I would be especially grateful for example implementations.
