If I remember correctly, there is the old "comma delimited and quoted characters" format known as CSV, Comma Separated Values and then there is the generally blocked-record format that we used to call SDF, System Data Format. Excel can take the first one pretty much verbatim but the second one will require you to set up a parsing template (again, I am doing this from memory and have not touched Excel in 8 years.)
Anyway, if the Op has problems, the two topics are well represented in Google searches.
