Since the data grid component is depricated, this whole module should be updated with upto data content.
I manged to get it to work with the documentation, although there was a missing step in https://docs.mendix.com/refguide/using-the-excel-exporter/ that you need to call the template microflow from the market place module
Thank you for this comment Toby. For each learning path we list on which Mx StudioPro version it is based. This means that you can have a different experience if you use a later version. We are reviewing the learning paths 1 by 1 and are updating to more recent Mx versions and indeed we will then remove references to deprecated elements and replace them with the corrent widgets.
