Grabbing information from .xls with javascripts

[Wilson Mui]

Does anybody know if there is a good way to grab information from an xls sheet with javascripts. Or in general if there is a good way to grab information so that I can create one of those windows on a webpage that has changing text. Like on Msnbc.com or something.
I can't do server-side code, because I am not running a real webserver to do this. So I would imagine my options are greatly limited.
But if somebody wants to give me a headsup in terms of how a website like msnbc.com does those internal windows (not the pop-ups) that have changing information depending on where you click (like population of US States) I would appreciate that as well.

Server side code would make this easier!
JavaScript can not read anything really other then a js file. There are tricks you can use to load the page into a hidden frame and read the innerHTML and rip it apart, but that is not efficient.

I hope you ment ".xsl" when you mentioned "xls" stylesheets... If you have access to the creation of the xsl you could arrange it to write html code for you, if html is what you want... more details would be welcomed...
