In Jan 2007, "Convert waypoint data in Excel file to gpx file?" thread created - some useful ideas/links, but mostly now dormant.\nUnder XP, I used POIconverter - cranky, but with persistence, effective; and ok with OSGB. Now using Win10.\nI can make the Excel column layout, and filetype, as required. Eg, concatenation and .csv? OK. But need clear novice-level instructions.\nThe exported file will be opened+saved in Tracklogs, or a Garmin Etrex.
