How to fix the error Uncaught exception 'PHPExcel_Reader_Exception'

I am trying to send two values to two cells in an excel ALREADY CREATED, which has the name query.xlsx ... but it turns out that I get the following error:

  Uncaught exception 'PHPExcel_Reader_Exception' with message 'Could not open consulta.xlsx for reading! File does not exist.' in C:\xampp\htdocs\importexcel\lib\PHPExcel\PHPExcel\Reader\Excel2007.php:343 Stack trace: #0 C:\xampp\htdocs\importexcel\f.php(15): PHPExcel_Reader_Excel2007->load('consulta.xlsx') #1 {main} thrown in C:\xampp\htdocs\importexcel\lib\PHPExcel\PHPExcel\Reader\Excel2007.php on line 343

my excel file is stored on my desk, and I'm using excel 2010

the code is as follows:

<?php
error_reporting(E_ALL);
set_time_limit(0);

 date_default_timezone_set('Europe/London');
 set_include_path(get_include_path() . PATH_SEPARATOR . 'lib/PHPExcel/');

 require_once 'lib/PHPExcel/PHPExcel/IOFactory.php';
 $fileType = 'Excel2007';
 $fileName = 'consulta.xlsx';

  // Read the file
  $objReader = PHPExcel_IOFactory::createReader($fileType);
  $objPHPExcel = $objReader->load($fileName);

  // Change the file
  $objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A1', 'Hello')
        ->setCellValue('B1', 'World!');

  // Write the file
  $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);
   $objWriter->save($fileName);

 ?>
