There are a few things to adjust other than the entry point such as the call to the XML class. But, you may easily work around that. The most important here is the Xsl transformation. This is done by the Xsl file where you will find all the code necessary to act based on some basic stuff. The goal is to have your spreadsheet to be properly set up in regards to various data types. You can have it evolved as per your own wishes. But, most of the work is already there. For me, I export dozens of dataset and this one generic code fits them all.
