How to embed an excel iframe so that it resizes to fit to 100% the width/height of the container?

I have embedded an excel sheet on my website using iframe.  I have set the container size to be 100% of the browser page and set the iframe width/height to be 100%. 

The width of the excel sheet goes to 100%, but then since the excel file is wider than the webpage, it extends past the end and you have to scroll to view the whole document.  I want the document to resize to be 100% of the width automatically without having to scroll to view the parts of the documents that are cut off.

Also, when I set the height to be 100%, for some reason, the height is just a small sliver of the document, maybe 200 pixles in height when the entire document is closer to around 3000 pixles.

I am assuming I am adding those values to the html for the iframe?  

Now that I am looking at it again, I do notice that the iframe itself fits to 100% the size of the container, but the excel document itself is actually what's not resizing.  I am guessing that might just be a limitation in the excel document/file itself and nothing can be done?
