If you need to export the parameters outside ArchiCAD, use Schedules.
You can add library part parameters to the schedule using Scheme Settings dialog / Add Fields / Library Part Parameters. In the next dialog Select Object by: Folder View (used Objects only), then select the library part you need, and add it’s parameters to the list.
After configuring the schedule, create a view from it, and add that to a publisher set. Finally select XLS format.
It’s a long way to set up first time, but only a click to refresh the XLS after that.
