Also with use of Excel. I took two columns with coordinates, manually added periods (.) after second digit. So I changed this:
2017-06-05 21:04:31,91,3,40,8,1,199,800,1000,500,34,239,524575880,169162529,0,384,726,16336,15,0,142,236
2017-06-05 21:04:32,92,3,40,8,1,199,800,1000,500,34,239,524575863,169162551,0,922,894,16076,15,0,143,235
2017-06-05 21:04:33,93,3,40,8,1,199,800,1000,500,34,239,524575854,169162572,0,885,871,16146,15,0,143,234
Into this:
name,desc,lat,lon
michal,1,52.4575880,16.9162529
michal,2,52.4575863,16.9162551
michal,3,52.4575854,16.9162572
To suit this site:
GPS Visualizer: Draw a map from a GPS data file. Than I paste it, and a map is ready.
Effect looks like this:
