Each subsequent line contains the values for one record.
The values in each row are separated by commas or other delimiters, such as spaces or semicolons.
The last record may or may not end with a new line.
The number of fields in each record should be consistent.
The values may be enclosed in quotation marks if they contain commas, new lines, or other special characters.
