Why Export Listview to CSV?
CSV file (Comma Separated Values, sometimes also called Comma Delimited) is a specially formatted plain text file which stores spreadsheet or basic database-style information in a very simple format, with one record on each line, and each field within that record separated by a comma. It is often used to exchange data between disparate applications. CSV has become a pseudo standard throughout the industry, even among non-Microsoft platforms because it is used in Microsoft Excel.
CSV files are often used as a simple way to transfer a large volume of spreadsheet or database information between programs, without worrying about special file types. For example, transferring a home-made address book from Excel into a database program such as Filemaker Pro could be done by exporting the file as a CSV from Excel, then importing that CSV into File maker.

Why Export Listview to Office OpenXML?
Office OpenXML has its own advantages. Office OpenXML, or Extensible Markup Language is a set of rules for encoding documents in machine-readable form. The real power of Office OpenXML comes from the fact that with Office OpenXML, not only can you define your own set of tags, but the rules specified by those tags need not be limited to formatting rules. And the most benefit of Office OpenXML is that because you are writing your own markup language, you are not restricted to a limited set of tags defined by proprietary vendors. Furthermore, Office OpenXML allows you to define all sorts of tags with all sorts of rules, such as tags representing business rules or tags representing data description or data relationships.
