Finally got Python paths straightened out, and installed numpy, scipy, and pandas with pip. It is fairly easy, but everything has to be just right, or nothing works.
There are too many permutations and alternatives...

After many challenges, finally was able to Read a CSV text file of point coordinates with Pandas, into a pandas DataFrame(), a type of super Deluxe "array" in Python.
It only took 3 lines of code, but I searched a couple of hundred example lines of code...

A superb link: https://datascienceparichay.com/article/read-csv-files-using-pandas-with-examples/

The math should not be too hard.
Re save to X,Y,Z,curveindex should be fairly easy.
