Good day guys,
I'm wondering if anyone has made an Excel spreadsheet to convert between NZ Map Grid to WGS 1984 Co-Ordinate systems? I normally use the LINZ website but I have run into a situation where it would not work (namely some of my data rows have no Northings/Eastings). LINZ has the formulas on their website and it's been on the radar to make one of these sheets myself, however I do not have the time right now to do so.
Therefore I thought I would crowdsource - has anyone done it and be willing to share it?
