What is a .xpt file?

File Extension Details

The XPT file format, also known as the SAS Transport file format, is a platform-independent data format developed by the SAS Institute. It was specifically designed to facilitate the exchange of SAS datasets between different operating systems and hardware architectures. Because different computer systems store data in different binary formats (such as big-endian versus little-endian), the XPT format acts as a standardized container that ensures data integrity and compatibility when moving information between disparate environments. It is widely used in the pharmaceutical and clinical research industries, as the U.S. Food and Drug Administration (FDA) mandates the use of the SAS Transport format (specifically version 5) for the electronic submission of clinical trial data. The format is strictly defined, limiting variable names to eight characters and restricting certain data types to ensure maximum portability across legacy and modern systems.
