What is the recommended/ good way for installing PHPExcel Library files in Cpanel?

Hi all, My site has a form. That form has a date and an export button. When the user clicks the export to Excel button, the SQL table is exported to an Excel file that downloads automatically based on the selected date. This is i'm trying now. Make sure to download the PHPExcel library and place it in the same directory as this script. Also, make sure to update the filename and file path as needed for your server. Is this possible?
