What is the difference between an XPORT and CPORT file format?

The SAS Transport file format (XPORT) is an openly documented file specification maintained by SAS, a commercial company with a variety of software products for statistics and business analytics. The CPORT file format is not openly documented. In Oracle Clinical One Platform, SAS Transport File Formats are currently running on Version 8.

If you need to make a decision on what file format to choose when extracting data for regulatory submissions, learn more about the differences between the SAS Transport file formats XPORT and CPORT. For more information, see SAS Transport File Format (XPORT) Family. Moreover, we recommend you consult the SAS Help Center.
