Text points to autocad to points in civil 3D

Text points to AutoCAD to points in civil 3D. DNG file is converted to the AutoCAD format. But everything is in text format. I need to convert these text elevations in AutoCAD to points in civil 3D to create the surface and calculate the volume. How to do it? Now, I have to create points manually and it is very large area, with more than 200 000 points. It will take few weeks to finish. Is there any easier methods available to convert this text to civil 3D points?
