5000 named OSGB GRs in Excel. Convert to .gpx, .loc, or similar.

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

There is a post about gpsbabel, this program will convert *.csv files to (and from) *.gpx files for you. If you start with a *.gpx file and convert it to *.csv using gpsbabel, then examine the resulting *.csv in Excel, you can see what format gpsbabel requires as an input file in order to create a working *.gpx fle

Good idea, reversing the conversion. But OSGB? Anybody done the conversion I want in gpsbabel?
