The "waypoints" are actually just names derived for each listed cache. This was suggested by other members in order to have a coherent naming convention to use when loading them into one's GPS unit. Since many units only take 6 character names, the convention was suggested using GC (geocache) followed by a hexadecimal number. The remaining 4 spaces after 'GC' would allow 9999 total caches in decimal, but many, 65000+ in hex. See
As for a list or spreadsheet containing the waypoint names and their respective coordinates, I don't know if one exists. Many have requested such a list as it would allow us to simply upload all currently known caches in one shot, however maintaining it might take some work.
