First make sure in Excel that the Lon/Lat are formatted in decimal
degrees (not D-M-S or anything else). Then do Save As... and choose
CSV, a comma separated text file.<br>
Now start GRASS in a LOCATION based on EPSG:4326 and run v.in.ascii.
be sure to set the fs (field separator) parameter to ',' like in the
CSV file.<br>

Create a new location based on EPSG:32729. In this location run
v.proj, pointing to the Lon/Lat location and mapset, and the point
vector you imported above.<br>
