What are common pitfalls when generating and opening Excel files using PHPExcel?

Common pitfalls when generating and opening Excel files using PHPExcel include not properly handling file paths, not setting the correct headers for file downloads, and not properly handling errors during file generation. To solve these issues, make sure to use absolute file paths when saving or opening Excel files, set the correct headers for file downloads to ensure proper file handling by the browser, and implement error handling to catch any issues during file generation. 

// Example code snippet for generating and downloading an Excel file using PHPExcel

require 'PHPExcel/Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Add data and formatting to the Excel file

// Set headers for file download
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="example.xlsx"');
header('Cache-Control: max-age=0');

// Save Excel file to php://output
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
