Date and Datetime using PHPExcel function writes in excel as Text - php

Question

I have a problem with PHPExcel function, this is my code:
<?php
# Load slim WP
define( 'WP_USE_THEMES', false );
require( './wp-load.php' );
# http://phpexcel.codeplex.com/
require_once dirname(__FILE__) . '/Classes/PHPExcel.php';
global $wpdb;
$query = "Select

foreach( $cell_definition as $column => $value ){
switch($column) {
case 'G';
case 'H';
$val = '=DATEVALUE("'.date('Y.m.d',strtotime($result[$rowCount][$value])).'")';
$objPHPExcel->getActiveSheet()->setCellValue($column.$cell, $val);
break;

$val = date('Y.m.d H:i:s',strtotime($result[$rowCount][$value]));
$objPHPExcel->getActiveSheet()->getStyle($column.$cell)

$rowCount++;
}
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="iPortal_Atskaite_'.date('Y-m-d_H.i.s', strtotime('+3 hour')).'.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;
I'm using switch for columns, where I need a different cell format.
Column G and H I need format 2015.10.05 (yyyy.mm.dd) And for column L 2015.10.05 12:03 (yyyy.mm.dd H:i).
Function getStyle() doesn't work, and returns the same value. If output as =datevalue, which is excel function, all is ok, but it doesn't work with time.
Also, if I press edit cell in excel and press enter, that date converts to normal date for excel and all works fine.
So, the problem is with output formatting. How can I define it? For other columns, for example for numbers, all is ok.

You need to convert your dates and date/times to an MS Excel serialized datetime stamp.... MS Excel does not automagically convert strings to dates for you, nor does simply setting a style change the actual value (a string in your case) that's stored in the cell in any way.
PHPExcel provides several different methods in the PHPExcel_Shared_Date class that will let you do these conversions.
$dto = new DateTime($result[$rowCount][$value]);
$dateVal = PHPExcel_Shared_Date::PHPToExcel($dto);
$objPHPExcel->getActiveSheet()->getStyle($column.$cell)
->getNumberFormat()
->setFormatCode("yyyy.mm.dd h:mm");
$objPHPExcel->getActiveSheet()->setCellValue($column.$cell, $dateVal);
