Creating Data type from excel

Hi

I have a excel file which has a column with 200 fields

I just have to create a Datatype with this 200 fields....When i tried using "insert rows" option it inserts 200 blank rows but when i copy the entire column from excel it gets copied in the single field in data type only

Do I need to manually create each field or is there a way to copy the fieldnames from excel column into data type
