convert maidenhead to lat/lon - lifetime map?

I am trying to make my own lifetime wspr map since the site map only goes back 24 hours. I've saved all of my activity in an excel file. I've found programs to convert .xls to an adif file and then to a kml file or map but this adds a lot of steps. Has anyone figured out an excel formula or macro I to convert maidenhead gridsquares to lat/lon?
thanks
