UIAutomation question - fetch and save data from user to Excel

Hi there
i want to tell uipath to take 2 data from user with input method and save in each row and 2 column one by one after another. for example nick name in first row and first column and the second data which could be Last name in first row and second column.
thanks alot by the way and i am so confused using for each row i think it goes with this activity as can make uipath read every row in excel one by one.
