How do I show an embedded excel file in a WebPage?

I want to allow an Excel report to be viewed embedded in a WebPage... is there a way?

I don't want to use an ActiveX, or OWC (Office Web Components), I just want to open an existing file from the internet explorer application.
I don't want users to download and then open it.

Using an iframe wouldn't be a problem, but my preliminary tests weren't successful

Any ideas? Is it at all possible?

Solution

This has to do with the local person's browser set up and not really anything you can do on your end. If they click a link with the .xls(x) extension, the browser determines if it wants to open it itself or in a new window.

Here 2 microsoft pages on how to change these settings:
