'Embed spreadsheet in a powerpoint in sharepoint

I want to embed specific cells from a spreadsheet in a powerpoint presentation. I have seen this done before with macros (I think), but I have never done it myself. I have done a little googling and am coming up with 50 solutions. Can someone help me narrow it down.

The big gotcha here is that both of these files will be in one folder in a document library in a sharepoint site. The other gotcha, which is kind of a given, is that I want the ppt to update to latest excel data when it is opened.
