one more thing - it is possible that you have just pure GPS data, so fo this coordinates you need to apply that:
degrees + minutes/60 + seconds/3600
like that :
float GPSDatToDegree(float flo)
{
int kGrad = (int)(flo / 100);
return kGrad + (flo - kGrad * 100) / 60;
}
input parameter is the longitude or latitude from the NMEA sentance (GPS) that looks like
$GPRMC,220516,A,5133.8
5133.8
N North/South
00042.24 current Longitude
W East/West
So you can call GPSDatToDegree(5133.82)

From GPS it comes each second - just to clarify.
You need to convert these values into your screen coordinates.
The points in your excel sheet are floats, probably.
