First of all, by wiring the constant 10 to the Read From Spreadsheet VI, you're reading all ten rows. You don't need the while loop in that case. You could also wire a -1 and get ALL rows and then process the resulting 2D array. You are also using the Index Array improperly, you've wired constants which means you're going to get the same row/column everytime. Use a For loop to process each row.
I've attached a sample vi that takes your spreadsheet data and sorts by the first column
