I have coordinates in Korea 2000 EPSG:5181 projected coordinate system.
Is there a way to make a formulation in excel to convert these coordinates to lat long (WGS84)?

I would suggest looking into these two sources Converting UTM to Latitude and Longitude (Or Vice Versa)
This program was recently updated using the formulas of Charles Karney (2010). His paper claims accuracy of a few nanometers. Excel has 15-digit accuracy, so the spreadsheet doesn't achieve that level, but is accurate to about 0.01mm.
