What is a flat file? A flat (or fixed width) file is a plain text file where each field value is the same width and padded with spaces.
It is much easier to read than CSV files but takes up more space than CSV. We examine the CSV value and remember the
longest width for each field. We then output each field padded to the longest width.
We add one additional space (optionally another character) before each field. Each field can be converted to
upper case or lower case. You can left justify the text, right justify text, or center justify each field value.
We also will convert a CSV or Excel data to an ASCII Table by checking "ASCII Table-ize It".
