## Main Question or Discussion Point

Hi,

I have imported a data set from EXCEL that is 18 columns wide and 25 rows long. Each row of data appears within it own set of brackets as expected. I am able to pull out individual elements of the array. However, I want to plot column 2 vs column 4. How might I extract those two columns of data from my imported data? Moreover, the first two rows are text that I would prefer to omit.

Data format:

{a11,a12,....a118}

{a21,a22,....a218}

.

.

.

{a251,a252,...a2518}

Any help would be appreciated. I cannot find a similar topic at the Wolfram site.
