Export HTML data table to Excel using POI

Can you please let me know, how we can proceed in this case we have a pure HTML data in the form of Tables which should be converted to proper excel sheet.

This is the source code which I have written, I get an exception --> Error: Invalid header signature; read 0x6D78206C6D74683C, expected 0xE11AB1A1E011CFD0|#]

    // Resulting byte stream from the DB
    resultBytes = dokumentSession.getXlsZuAuftrag(ts);
    if (resultBytes != null && resultBytes.length > 0) {
        try {
            InputStream fos = new ByteArrayInputStream(resultBytes);
            HSSFWorkbook workbook = new HSSFWorkbook(fos);
            workbook.createSheet("sheet1");
            FileOutputStream fileOut = new FileOutputStream("ipa_loader.xls");
            workbook.write(fileOut);
            fileOut.close();
        } catch (Exception e)
        {// Catch exception if any
            System.err.println("Error: " + e.getMessage());
        }
    }

Please let me know any inputs on this, any help is appreciated.
