I downloaded my locations as geoJSON. It was simple to remove all but the place names, and they are already in a format usable by www.gpsvisualizer.com/geocoder/
That is a quick way to get coordinates for about one name per second. Putting the results back in the original geoJSON format would also be simple.
Narrowly missed a major screw-up. In my export, all may coordinates were [0,0] except one. Fortunately, just before re-import, I happened to see that this one was "wrong." Not really, but the geoJSON format for whatever reason puts the longitude before the latitude. Had to reverse my formatting, swap them, and format again.
