Hi,
I just worked on same functionality where i used a button to create excel file with context data and save in local system.
Use the following code under a button, So on click of button you can directly get the excel file saved in to your desktop without saving on the server
String ordcaeno="000"sysdate".XLS";
String str = "";
for(int j = 0; j< wdContext.nodeZflash_File().size(); j++)
str =str"\n" wdContext.node<<ABC_File().getABC_FileElementAt(j).getRecord();
try
IWDCachedWebResource resource = WDWebResource.getWebResource
  str.getBytes("UTF-8"), WDWebResourceType.UNKNOWN
resource.setResourceName(ordcaeno);
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(resource.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal()),
resource.getResourceName()); 
window.show();
catch(Exception ex)
wdComponentAPI.getMessageManager().reportException( new WDNonFatalException(ex), false );
