Automatically assign values to intervals of imported CSV data

I am trying to assign values to CSV data, and I need to assign "coordinates" to data while keeping it in single vector. For example, for 100 points taken within a 10x10 grid the data would read (1,1); (2,1).......(10,1); (2,1)....(2,10)....(10,10) where the number and spacing of the measurements is input by the user.

Any suggestions would be a huge help Thanks!

I do not understand the question.

It might be more helpful if you were to elaborate on your question. Could you give us some sample input and expected output to work with?
