I have a two dimensional array after splitting a text document into three different columns.

You split with
    my @splits = split (',', $line);
to the array  @splits which has one dimension. On what do you base your assertion that you have a two-dimensional array?

You assign the first element of  @splits to  $first_value and then print  $first (which is never defined) immediately afterward. How does | can that work with strict enabled?

Can you supply a short, representative example or two of your input data? We could then use this for testing various alternatives.

Also, please see the Short, Self Contained, Correct (Compilable), Example discussion.

Give a man a fish:  <%-{-{-{-<
