title: How to write to an existing .xlsm file through Perl
body: <p>Could someone please clarify if there is any Perl package to edit a pre-existing .xlsm file? </p>
  
  <p>I tried few examples posted in CPAN page and this site which use the combination of  WriteExcel and ParseExcel::SaveParser. They are not working for .xlsm file.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Thanks.</p>
