Hi Alexander,
1.Conversion from ShapeFile to Topojson convert passed but outputs do not open empty via QGIS
Conversion passed for two inputs.
Both output files do not open in QGIS.
4.Data: inputs/outputs/logs…...geometry can’t be render by viewer. It’s actually correct topoJson...see rusult in Qgis or other viewer you can use new option ‘TrimTo2DGeometry’...
