You have multiple problems in your code,

This loop Element table : doc.select("gridMarket") Result might not come, so use doc.getElementById(<>) to fetch the info.

  Element table = doc.getElementById(<<Id of table>>);
  if(table != null) {

    int rownum = 0;
        for (Element row : table.select("tr")) {
            HSSFRow exlrow = sheet.createRow(rownum++);
            int cellnum = 0;
                 for (Element tds : row.select("td")) {
                     StringUtils.isNumeric("");
                     HSSFCell cell = exlrow.createCell(cellnum++);
                     cell.setCellValue(tds.text());
                 }

  }

Once you wrote the data to the sheet you have to flush it to file system something like follows and should close the workbook.

        File file = new File("Report" + new Date().getTime() + ".xlsx");

        System.out.println(file.getAbsolutePath());
        FileOutputStream outputStream = new FileOutputStream(file);
        workbook.write(outputStream);
        workbook.close();
