Is there a specific best practice for handling Excel file formats in PHPExcel, such as preferring xlsx over xls?

When working with PHPExcel, it is generally recommended to handle newer Excel file formats like xlsx over older formats like xls. This is because xlsx files are more efficient, have larger data capacity, and are compatible with newer versions of Excel. To ensure compatibility and better performance, it is best practice to prefer xlsx over xls when working with PHPExcel. 

// Example code snippet to handle Excel file formats in PHPExcel
$inputFileType = 'Excel2007'; // Set input file type to xlsx
$inputFileName = 'example.xlsx'; // Specify the input file name

$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);

// Work with the loaded Excel file
