Try codding as a simple layout in your view component, then try this at the end of the code

//code goes here
$this->layout=false;
Yii::import('application.extensions.phpexcel.JPhpExcel');
$xls = new JPhpExcel('UTF-8', false);
$xls->generateXML('name_of_the_sheet');
//end of the view

This will generate you an excel file to save
