"CSV" or Comma Separate Value has evolved. If you actually use commas, then there is the problem of commas within quotes. The program and regex logic to deal with with this is actually quite complex.

An alternate to the comma that is used in many data base outputs is the "pipe" or | symbol. Although common in programming languages, this symbol is almost unknown in name, address, department name fields, etc. A database output that uses the "|" instead of the "," to separate fields is also known as a "CSV" file. Microsoft Excel can easily import CSV files separated by "|".

If I have a choice when generating the file, I use "|". When I have to read a file from some other source, very often but not always it uses "," and I have to deal with that.

So, if you generate the file, I would use "|" instead of "," because it makes the parsing easier - which is reason enough.

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
