How do I use block functions with a file that has channel names in the rows

Hello,

I hope the title isn't too confusing, but I have data in the format shown below:

Chn_1    1      2      3      4      5

Chn_2   a      b      c      d      e

Chn_3   1.1   2.1   3.1   4.1   5.1

Chn_4   1      2      3      4      5

I want to be able to use the GetCellBlockor or GetStringBlock with this data, but it seems to require that the channel names are going across the columns instead of down the rows. 

Does anyone have a clean way grab these channel and add them with the correct data type to the data portal?
