New Post: Currency Euro sign

enclose the currency symbol in double quote (")
like this:
a. if u enclosed the format pattern in double quote, escape it by adding backslash before the double quote that enclosed ur format symbol

$objPHPExcel->getActiveSheet()->getStyle('G14')->getNumberFormat()->setFormatCode(" \"€\" #,##0.00"); 

b. if u enclosed the format pattern in single quote

$objPHPExcel->getActiveSheet()->getStyle('G14')->getNumberFormat()->setFormatCode(' "€" #,##0.00'); 

whatever option above u chose, the result will be like this: € 3,999.22
