Error :

Plugin::load('CakeExcel', ['bootstrap' => true, 'routes' => true]);

in my AppController

$this->loadComponent('RequestHandler', [ 'viewClassMap' => ['xlsx' => 'Cewi/Excel.Excel'] ]);

in my Route.php

Router::extensions('xlsx');

Then my template is like the following

And my Layout

my composer
