This is known bug https://github.com/PHPOffice/PHPExcel/issues/1212 To avoid it you can

downgrade php
upgrade to phpspreadsheet
use Excel2007 writer instead of Excel5
try to suppress warning with error_reporting(E_ALL ^ E_WARNING );

Like voter said, it's a known bug on the Github and won't be fixed because the developers are focussing on a new library. However, instead of down- and upgrading your environment, you could edit a single line and keep your existing implementation.

As seen in the Github thread:

Go to PHPExcel/Writer/Excel5.php
Around line 372, find $endCoordinates = PHPExcel_Cell::stringFromColumnIndex(PHPExcel_Cell::stringFromColumnIndex($iInc - 1));
Change it to only call the function once: $endCoordinates = PHPExcel_Cell::stringFromColumnIndex($iInc - 1);
