how to make New lines in a cell using phpexcel

$objPHPExcel->getActiveSheet()->setCellValue('H5', "Hello\nWorld");
$objPHPExcel->getActiveSheet()->getStyle('H5')->getAlignment()->setWrapText(true);

Works for me...

You should always use double quotes when you add escape sequences in a PHP string.

Improved answer based on Ravin and others

$objPHPExcel
  ->getActiveSheet()
  ->setCellValue('H5', "Hello".PHP_EOL." World");

$objPHPExcel
  ->getActiveSheet()
  ->getStyle('H5')
  ->getAlignment()
  ->setWrapText(true);

you should use 'r' to break into new line into excel with php

and use double quotes when you add escape sequences in a PHP string.

  $objPHPExcel->getActiveSheet()->setCellValue('H5', "Hello\r World");
  $objPHPExcel->getActiveSheet()->getStyle('H5')->getAlignment()->setWrapText(true);
