Untested, and no guarantees, but try something like this:
String mimeList = "application/vnd.ms-excel,application/
msexcel,application/x-msexcel,application/x-ms-excel,application/
vnd.ms-excel,application/x-excel,application/x-
dos_ms_excel,application/xls,application/vnd.openxmlformats-
officedocument.spreadsheetml.sheet";
myFileUploadWidget.getElement().setPropertyString("accept", mimeList);
