Apache POI Excel XLSX save as PDF - excel

Question

Currently I work using Spring Framework. I was asked to print a report with a PDF output that retrieves data from a SQL database, but the project I'm working on has Apache POI installed where the output is Excel XLSX.
Is there a way to convert Excel XLSX format to PDF?
I already have Apache POI and recently added iTextPDF.

EDIT : This is the code to generate XLSX file
#RequestMapping(value = "/download", method = RequestMethod.POST)
#PreAuthorize("hasAuthority('CTRL_REPORT_READ')")
#ResponseBody
public void download(#Valid #ModelAttribute ReportForm reportForm, BindingResult result, RedirectAttributes redirectAttrs, HttpServletRequest request, HttpServletResponse response) throws IOException {
logger.debug("IN: reimbursement/dowload report-POST");
XSSFWorkbook workbook = null;
try {
workbook = new XSSFWorkbook();
downloadExcel(reportForm, workbook);
response.setContentType("application/vnd.ms-excel");
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
String fileName = "Reimbursement Report " + sdf.format(new Date()) + ".xlsx";
response.setHeader("Content-disposition", "attachment; filename=" + fileName);
workbook.write(response.getOutputStream());
} catch (Exception e) {
logger.error("Error occurs when add new data in method reimbursement with error message : " + e.getMessage());
redirectAttrs.addFlashAttribute(AppDataConstant.ERROR_FLASH_RESP, "Download reimbursement report failed");
} finally {
if (workbook != null) {
workbook.close();
}
}
}
Thank you very much before
