+=== PHPExcel ===
+  * Download a copy of PhpExcel helper and component for CakePHP 2.x: [[https://github.com/segy/PhpExcel]].
+  * Copy files to respective folders in CakePHP app.
+  * Get PHPExcel updates from [[https://github.com/PHPOffice/PHPExcel]], and update helper files in ''[app]/vendor/PhpExcel''.
+  * See documentation:
+    * [[https://github.com/segy/PhpExcel/blob/master/View/Helper/PhpExcelHelper.php|PhpExcelHelper]]
+    * [[http://openxmldeveloper.org/blog/b/openxmldeveloper/archive/2009/05/07/4606.aspx|Use PHP to create Open XML Spreadsheet reports]].
+In PhpExcel helper, edit function ''createdWorksheet()'' to look like this:
+<code php>
+public function createWorksheet() {
+    // load vendor classes
+    App::import('Vendor', 'PHPExcel');  // <-- Check class name
+    $this->_xls = new PHPExcel();
+    $this->_row = 1;
+    return $this;
+}
+</code>
+In controller, add references to helper:
+<code php>
+class MyController extends AppController
+{
+   ...
+   public $helpers = array('Html', 'Form', 'Session', ..., 'PhpExcel');
+   ...
+}
+</code>
+In controller, add action to generate data:
+<code php>
+...
+function actionGetData($id)
+{
+    $data = ClassRegistry::init('Customer')->find('all', array(
+                'conditions' => array('Customer.id' => $id),
+            ));
+    $this->set('data', $data);
+    // Create a view that does not display any html header code except for the Excel data.
+    // To do this, set the layout to be 'ajax', which just happens to contain no html outside the main content.
+    $this->layout = 'ajax';
+}
+</code>
+Create view. Eg: actiongetdata
+<code php>
+// create new empty worksheet and set default font
+$this->PhpExcel->createWorksheet()->setDefaultFont('Calibri', 12);
+// define table cells
+$table = array(
+    array('label' => __('User'), 'filter' => true),
+    array('label' => __('Type'), 'filter' => true),
+    array('label' => __('Date')),
+    array('label' => __('Description'), 'width' => 50, 'wrap' => true),
+    array('label' => __('Modified'))
+);
+// add heading with different font and bold text
+$this->PhpExcel->addTableHeader($table, array('name' => 'Cambria', 'bold' => true));
+// add data
+foreach ($data as $d) {
+    $this->PhpExcel->addTableRow(array(
+        $d['User']['name'],
+        $d['Type']['name'],
+        $d['User']['date'],
+        $d['User']['description'],
+        $d['User']['modified']
+    ));
+}
+// close table
+$this->PhpExcel->addTableFooter();
+// Save to Excel file
+ob_end_clean();  // remove all output (very important, otherwise data is garbage)
+this->PhpExcel->output('MyExcelFile.xlsx');
