PHPExcel Error when opening outputted Excel file - export-to-excel

Question

I hope I'm in the right place. I have this PHP that exports data from SQL to XLSX.
<?php
$conexion=odbc_connect("syb_master","sa","server");
$sql = "Here's the query";
$exec = odbc_exec($conexion,$sql);
$resultado = odbc_result_all($exec);
$registros = odbc_num_rows ($resultado);
require_once '../Classes/PHPExcel.php';
if ($registros > 0) {
$objPHPExcel = new PHPExcel();
//Informacion del excel
$objPHPExcel->
getProperties()
->setCreator("ingenieroweb.com.co")
->setLastModifiedBy("ingenieroweb.com.co")
->setTitle("Exportar excel desde mysql")
->setSubject("Ejemplo 1")
->setDescription("Documento generado con PHPExcel")
->setKeywords("ingenieroweb.com.co con phpexcel")
->setCategory("ciudades");
$i = 1;
while ($registro = odbc_fetch_object ($resultado)) {
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A'.$i, $registro->name);
$i++;
}
$objPHPExcel->getActiveSheet()->setTitle('Simple');
}
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="ejemplo1.xlsx"');
header('Cache-Control: max-age=0');
$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter->save('php://output');
exit;
odbc_close($conexion);
?>
It works when exporting to XLS, but when I export to XLS, everything seems to be correct except for the fact that when done, excel can't open the file. It gives the error: "Excel can't open the file because the file format or file extension is not valid."
I think it's because the query has a lot of data, but I'm not sure. I'm new to phpexcel. I hope you can help me. Thanks!

/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');
define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');
/** Include PHPExcel */
require_once 'Classes/PHPExcel.php';
// Create new PHPExcel object
//echo date('H:i:s') , " Create new PHPExcel object" , EOL;
$objPHPExcel = new PHPExcel();
// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(50);
