Hi Alexander,
When converting any format with any format especially for geometry to Csv format and vise versa,
Aspose skips on geometry at that moment (there is a plan to support it in future).
Csv show only the data,…... MapInfo TAB - .tab, .dat, .map, and .id files-...“MapInfo File” driver MapInfo TAB .tab, .dat, .map, .id Layer → Add...
