Hi,
Your points are done on a sketch, so easy way is to save CATPart as igs file.
The igs file can be open with WordPad or Scite or Notepad++ (it will keep the text formatting) or with any other software which can read files based on text inside - case of the igs files. Usually you can see the coordinates of the points in the rows which start with number 116 (which if I remember correctly means point in igs files).
In your particular case search for Sketch.1 and under this row you will find what you need, for example:
116,0.0,1004.704829,156.6925468,0,0,0; 1P 1
116,0.0,1002.391412,159.007152,0,0,0; 3P 2
116,0.0,1001.717075,162.2252189,0,0,0; 5P 3
116,0.0,1002.839395,165.292717,0,0,0; 7P 4
116,0.0,1005.358351,167.4462534,0,0,0; 9P 5
116,0.0,1008.178667,169.1814322,0,0,0; 11P 6
That means for first point is at x=0.0 y=1004.704829 z=156.6925468
Last 3 zero numbers on the same row is the position of the axis system…..
Of course you can do this also in Excel, still, be aware of numbers of the rows limitation in Excel - no more then 63500 if I remember correctly...
