I have been working with importing a csv file into excel and then saving the
output as a prn file that we will use for uploading.

My next challenge is to append at the end of this Excel file (before saving
as a prn) with a second file that will have different fixed length
requirements than the original import. The second file will consist of a
single row but again the fixed length requirements are different than the
original import.

Any ideas how to automate this or since it is a single row should we just
input manually? Any advice?
