I find myself manually converting points of x and y coordinates to lat and lon coordinates online, one point at a time (N = 8200).
Is there a way to automatize this process where it also takes the projection into consideration?
I am pretty flexible with the program using, as long as it is not ArcGIS and Java.
Here is a sample
x y lat lon -3145588.03 5018975.86 63.30 177.62 -3115010.95 5010633.39 63.55 177.94 -3084474.59 5002315.52 63.80 178.28
