Facing issue with PHP Excel Export/Import - php

Question

I am trying to export record from db to excel using PHP (Codeignitor) and then Import the same excel file again using PHP (Codignitor)
Export Code IS:
header('Content-type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename=' . date('d-m-Y') . '.xls');
$export .= '<table border="1">';
$export .= '<tr>';
$export .= '<td>Gate Name</td>';
$export .= '<td>ID</td>';
$export .= '<td>Name</td>';
$export .= '<td>Rank</td>';
$export .= '<td>Time</td>';
$export .= '<td>Entry Type</td>';
$export .= '<td>Work Place</td>';
$export .= '<td>Car Type</td>';
$export .= '<td>Car Number</td>';
$export .= '<td>Inspector Name</td>';
$export .= '</tr>';
foreach ($result as $row) {
$export .= '<tr>';
$export .= '<td>' . $row->gate_name . '</td>';
$export .= '<td>' . $row->soldier_id . '</td>';
$export .= '<td>' . $row->soldier_name . '</td>';
$export .= '<td>' . $row->soldier_rank . '</td>';
$export .= '<td>' . $row->time . '</td>';
$export .= '<td>' . $row->entry_type . '</td>';
$export .= '<td>' . $row->work_place . '</td>';
$export .= '<td>' . $row->vehicle_type . '</td>';
$export .= '<td>' . $row->vehicle_number . '</td>';
$export .= '<td>' . $row->inspector_name . '</td>';
$export .= '</tr>';
}
$export .= '</table>';
echo $export;
When I try to emport the downloaded file using This PHP Library - SimpleXLSX.
$SimpleXLSX = new SimpleXLSX($filename);
$data = $SimpleXLSX->rows();
the $data is empty
this library work if I create an excel file by self using MS Excel.
if I try to get file content by using
print_r(file_get_contents($filename));
It return the content with HTML code
Like
<table border="1">
<tr>
<td>Gate Name</td>
<td>ID</td>
<td>Name</td>
<td>Rank</td>
<td>Time</td>
<td>Entry Type</td>
<td>Work Place</td>
<td>Car Type</td>
<td>Car Number</td>
<td>Inspector Name</td>
</tr>
<tr>
<td>Gate 2</td>
<td>1111</td>
<td>فارس الغامدي</td>
<td>ملازم اول</td>
<td>28/02/1435 07:01:00</td>
<td>دخول</td>
<td>قطاع رفحاء</td>
<td>جيب</td>
<td>Tuy 124</td>
<td>عبدالله</td>
</tr>
</table>
I think the problem is with header() function or encoding when Creating Excel file.
Please help me.
Thanks.

SimpleXLSX will read XLSX files and print HTML code, but you cannot convert HTML code to XLSX format using SimpleXLSX. Here's an example of how to do it in PHPExcel:
<?php
$date = date("m-d-Y-g-i-s");
// Include and instantiate PHPExcel object.
include '../lib/PHPExcel/PHPExcel.php';
include '../lib/PHPExcel/PHPExcel/Writer/Excel2007.php';
$objPHPExcel = new PHPExcel();
// Set metadata.
$objPHPExcel->getProperties()->setTitle("Price List $date");
$objPHPExcel->getProperties()->setSubject("$date Price List");
$objPHPExcel->getProperties()->setDescription("The active price list for $date.");
// Set active sheet index at zero.
$objPHPExcel->setActiveSheetIndex(0);
// Determine limit and offset.
if($_GET['limit'] > 0 && $_GET['offset'] > 0) {
$limit = $_GET['limit'];
$offset = $_GET['offset'];
} else {
$limit = 10000;
$offset = 0;
}
// Query the database.
$query = mysql_query("SELECT * FROM `items` LIMIT $offset, $limit") or die(mysql_error());
$c = 0; // Initialize index at zero.
// Set column dimensions.
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);
// Loop through data and insert it into their respective columns.
while($row = mysql_fetch_array($query)) {
$c++;
$objPHPExcel->getActiveSheet()->getCell("A$c")->setValueExplicit(stripslashes($row[strStock]), PHPExcel_Cell_DataType::TYPE_STRING);
$objPHPExcel->getActiveSheet()->SetCellValue("B$c", stripslashes(html_entity_decode($row[strDescription])));
$objPHPExcel->getActiveSheet()->SetCellValue("C$c", stripslashes($row[curPrice]));
}
$objPHPExcel->setActiveSheetIndex(0);
// Send headers to download XLSX file.
header('Content-Type: application/vnd.ms-excel');
if(isset($_GET[part]) && isset($_GET[of])) {
header('Content-Disposition: attachment;filename="Price List (Part '.$_GET[part].' of '.$_GET[of].') '.$date.'.xlsx"');
}
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');exit;
?>
Edit: Sorry, this is the code for PHPExcel, not SimpleXLSX. Here is the documentation for PHPExcel.
