How can I restructure an unfavourable 2D array format to 1D?

Question

A surface profilometer we use produces data in text files with five columns with data point ordering by row first; i.e. if you have the following data sample;
1      2      3      4      5
6      7      8      9     10
11    12    13    14    15
Then the data order follows the number order here.  I want to chop up this annoying format into multiple arrays by row (depending on the number of rows = for loop?) then splice them back together as a single column (transpose these arrays then build array?). Help!

Once you have a 1D array, the concept of rows and columns no longer exists.
In any case, reshaping is the right thing. Here's what I would do:
