How to extract data from Excel to 2d array?

Can anyone explain me how to properly make 2d array in UiPath and extract data to it?

I have data in two columns
85026113_226693195008605_7451868395722506240_n

And from that I would like to put it to the 2d array.

So every row of 2d array will be containing groups of data (colours on screen).

Any help?
