Adding topo points from a flattened CAD import. The elevations are in CAD text only. No Z elevations

Now I’m trying to export these points to excel or a CSV to model the topo that way. The “String to Number” node throws out a bogus error since points are still showing up and getting translated to the correct elevation. However the Data Export to Excel fails completely. I can’t get these damn point coordinates out.
Can someone please help? I can’t find a reason for this.
Thanks.
