Thank you, Monish.

Are you able to view it using Safari on the phone or does it say "unsupported format"?

Try another file that works in Safari and then try in UIWebView.

Also see this: http://developer.apple.com/iphone/library/qa/qa2008/qa1630.html

First make sure you are able to view the xls in Safari then try code like this:

- (void)viewDidLoad {
    [super viewDidLoad];

    NSURL *url = [NSURL URLWithString:@"http://www.yourwebsite.com/good.xls"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webView loadRequest:request];
}
