Shapefile

Hi

I have uploaded a CSV file to arc map with all my relevant data i need then joined it to a shapefile for geographical reference. I now need to export it as a shapefile as i'm going to be using it in Geoda. I can do this but when I open it up in Geoda and also in ArcMap it has renamed my column titles to 1, 2, 3, 4, etc instead of keeping the original names.

Does anyone know how to get the original column titles back and kept within a shape file?

Thanks
