Read data from Excel

Hello,

 I have as a task to read data from excel file. I've solved first problem and can now read data from the file. Data will be captured in collection field like A1; B1; A2; B2;. In this case I dont know there is new row and there is the next column. I can check ";" sign and loop, but its not nice.

My question is if there any other correct way to loop through the list ? Like row(1), column(0), column (1), next row(2), column(0), column (1)...

Please advice to use the right way.

 Cheers,

 Alex
