If you need to send multiple request then in the csv, give the input field as required.
Example:-
1st Cell:-N
2nd Cell:-Na
etc
But, check if there is a request being send for every word you type in the field to the server using fiddler or any other sniffing tool. If yes, then use the above approach. Also, you can try using jmeter recording for the scenerio.
If, not then you need to have one request which is sending the full variable i.e. Name.
Hope this helps.
