I’d like to export netclass assignments from KiCad into Altium (for our design house), either directly, or at least by exporting a spreadsheet that the design house could work from. The information doesn’t appear in the XML that is used for BOM and netlist generation.
Netclass assignments live in the project (kicad_pro) file. You should be able to parse the JSON and then extract them to whatever format Altium wants using a Python script or similar.
