I wanted to import GeoJSON files, but after installing the Background GP and Data Interop packages, I find that the FME Gallery contains only GML and WFS formats. This is with both ArcGIS 10.4 and ArcGIS 10.5 on advanced licence.
I tried this solution : ArcGIS 10.5 FME Data Interoperability ArcGIS Online reader not working
..but it did not make any difference.
I can use QGIS to get the files for now but is there a libary online where I can import FDS files?
