Answer 1

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);
