Linking Excel spreadsheets to intranet site

Is there any way that I can link to an Excel spreadsheet and have it open in Excel, rather than open inside the browser viewer? The macros that I have in the spreadsheet will not run inside the viewer, only in Excel.

function openIt(){
if(is.ns4){
netscape.security.PrivilegeManager.enablePrivilege('UniversalExecAccess');
java.lang.Runtime.getRuntime().exec ('excel');
} else if(is.ie4){
var sh = new ActiveXObject('WScript.Shell');
sh.Run ('excel');
}
}
