The XER file format is a proprietary project file format used by the Primavera P6 project planning and management application. Like MPP file format, this file format stores data related to project planning such as tasks, resources, timelines, and materials. Primavera is developed by Oracle and provides the capability of complete project planning and finds its applications in several practical fields such as oil and gas, construction, manufacturing, etc. It helps project managers plan, schedule, and control large-scale programs and individual projects by integrating with financial management and human capital management systems. Many software and APIs can read and convert XER files to other popular project file formats such as XML and MPP.
XER File Format
An XER file is a text file, and can easily be opened with a text editor. Opening project-related data in a text editor could be useful, but it is not easy to comprehend it by manually establishing links. This format is the most used one for exchanging data with other P6 databases. It has a relatively low level of control over data that has been imported from another format. Certain advantages that XER has on equivalent XML format include the ability to move global codes and calendars to project level and map codes, UDFs, resources, and calendars to existing values.
