Hi,
We may look into your desired features (support for PowerPivot, PowerView and GeoFlow) for MS Excel 2013. We appreciate if you could provide us some sample/template input Excel files containing PowerPivot, PowerView and GeoFlow definitions, some screen shots for the errors/issues in the output files (by Aspose.Cells). We will log ticket(s) for your requested features into our database and investigate them soon.
Thank you.
