Excel/Mathematica Extracting Data with a twist

[fujiheero]

I am trying to extract data to mathematica from Excel. I understand the Import function and i can get all my 2500 Points into Mathematica however, I only need to analyze every 100th or every 50th point to plot on my graph in mathematica. My question is:

Is there a way to extract data within a matrix but only extract every nth cell? (in either mathematica or excel).

Thanks in advance.

Use expr[[m;;n;;s]] to get every s'th element of expr.
