I want to use my PHPExcel Laravel application. I installed the library in the vendor directory. What is the method to call my controller and thereby implement this example: http://g-ernaelsten.developpez.com/tutoriels/excel2007/?page=fondements#L2.1
In the posts I read it just had to write to the header
Maatwebsite made a built a Laravel package for PHPExcel. You can find it here https://github.com/Maatwebsite/Laravel-Excel together with the documentation for it.
If for any reasons you prefer to not use this, you need to
include '/vendor/PHPExcel/PHPExcel'; include '/vendor/PHPExcel/PHPExcel/Writer/Excel5.php';
