Are those headers enclosed in double quotes ? How many headers are there ? Also it is not clear what delimiters between fields your excel file has but that information will be relevant when thinking about constructing a regex, table files can be comma-separated, tab separated, space-separated ..etc. Are you reading your file one line at a time ? It maybe useful to give a snippet of the code you tried to solve this problem and also a few lines of your file to see how they look like.
