Here is the part file. I have started with a super simple shape, and I know once I have the location of the first 2 rows, the rest are easy. But eventualy this would be a more complex curve.
I have tried exporting to a couple of formats, but so far none export any but the default coordinate system.
Once I have the points, they will be fed to a robot.

I exported a similar file to STEP. it returned good data but it returns in Cartesian coordinates with coordinates and vectors. You will need to convert this data to the desired format.
Have you talked to some of the CAM people to see if they know a simple method? A 5-axes milling machine crunches numbers like this for breakfast.
I think, my advice about Excel is not useful in your case.
Export to text-based file it is more interesting solution. Thanks to Antonius.
Take a look at Neutral (.neu) file.

4 origin 0.,1.75,0.707106781186547
2 coord_systems ->
e1, e2, e3 - coordinates of the axes (a vectors from the origin).
You can check this by placing Point - Offset Coordinate System and make the Analysis (Geometry Report - Point)
I think, "e1 2*0., 1." this is "e1 0., 0., 1."
