I'm looking for a way to convert a .csv file to .gpx (or .tcx) file on a Mac.
To match up a Garmin GPS file to a video file I wanted to edit the data. The only way seems to be to export to something you can open in Excel, then extract/modify the data there.
However, I'm not sure how to go back from there.
Any experience? There must be a converter out there somewhere, but I've struggled to find something that works with my Mac (OS 10.9).
