"the source data is XML with TT instructions in the file."

That's not really the source data, since you need to create the XML. Your solution creates an XML file using Templates, I was asking what the source data was, since you obviously have it in a perl script, you could use this data to feed both the preview (one method described above) and create the Spreadsheet (Excel::Writer::XLSX). Seems illogical to create a file in a certain format only to parse it back into perl just to present a preview.
