If you can get the data into a spreadsheet into = X,Y,Z=20 columns, it would be easy enough to have a script read each row of x,y,z = and=20 apply that to the position of a layer.

 

I have done a similar thing taking camera data from = a motion=20 control rig into AE.

 

If you are not in a huge rush, I could write the = script for=20 you once you give me a sample of the data.

 

You will probably need some kind of multiplier in = there to=20 make the values fit within you AE world.
