Will Spreadsheet::ParseExcel allow me to add data to the XLS file and then save? Here is my story so far: I wrote a Perl program to create and add data to a XLS spreadsheet using WIN32OLE. My company, now, will not let me install Excel on the server. So I now need to recreate the script so as not to use the actual Excel application. So I need to find a way to open, add data, and then save the XLS spreadsheet using Perl.
