For what it's worth, an awk script to create a CSV with the labels.
#
# AWK script to filter out a list of labels (global and local) from a
# CADStar net list exported from KiCad.
#
# Produces a CSV file with 2 columns of the labels.
# Strips out CR from the end of the netlist lines
# and puts it back at the end of the output line.
# Should work with any awk flavor but not tested.
#
BEGIN {print "Label,Label"}
{
if(match($1,".ADD_TER")) {
sub("/.*/", "",$4)
sub("\015", "", $4)
print $4 "," $4 "\015"
}
}
