  You can actually do this pretty easily with expressions.

  Create 4 2D nulls, one for each corner, and apply one of these expressions to each:

  // top right corner
L = thisComp.layer("3D Layer");
L.toComp([0,0]);

  // top left corner
L = thisComp.layer("3D Layer");
L.toComp([L.width,0]);

  // bottom right corner
L = thisComp.layer("3D Layer");
L.toComp([L.width,L.height]);

  // bottom left corner
L = thisComp.layer("3D Layer");
L.toComp([0,L.height]);

  Select the position property of each of these nulls, and from the Animation menu, choose Keyframe Assistant > Convert expressions to keyframes.

  Select one of the null’s position properties, then copy, then paste into Excel. You’ll get keyframe data for that point. Repeat for each of the nulls.
