        Workbook wb = new Workbook();
        File file = new File("C:\\Users\\17240\\Downloads\\1.xml");
        //将File转为inputstream流
        InputStream is = null;
        try {
            is = new FileInputStream(file);
        } catch (FileNotFoundException e) {
            throw new RuntimeException(e);
        }
        wb.loadFromXml(is);
        //转为2013版xlsx格式的Excel
        wb.saveToFile("C:\\Users\\17240\\Downloads\\2.xlsx", FileFormat.Version2013);
    }
}
