XER File

An XER file is a type of project scheduling file created by Oracle's Primavera P6, a popular project management tool. It holds important details about a project—such as tasks, timelines, resources, and materials—that help teams keep track of their project schedules. This format makes it easy to share project plans and updates across different Primavera systems and is commonly used in fields like construction and engineering.

Can I convert an XER file to Microsoft Project format?

Yes, you can convert an XER file to Microsoft Project format, though it involves a few steps. First, import the XER file into Primavera P6. Once in Primavera, export the project in a format that Microsoft Project can read, such as MPX or XML. You can then import this file into Microsoft Project. Keep in mind that due to differences between the software, some data may not transfer perfectly, potentially affecting details in the milestone chart, project timeline, or activity sequencing.

How can I open and view an XER file without Primavera P6?

While Primavera P6 is the primary application for opening XER files, alternative tools, like a XER reader, are available for viewing these files without the software. Applications like ScheduleReader and XER Manager Professional allow users to open and view XER files, providing a similar interface to Primavera P6. These XER readers enable users to audit project data, including tasks and schedules, without the need for the full Primavera P6 application.

For construction project managers, using Mastt is a smarter, more efficient way to open XER files for project scheduling and management. Unlike traditional XER readers, Mastt provides a cloud-based, intuitive platform that streamlines project tracking, reporting, and collaboration. To import an XER file in Mastt:

  1. Log in to Mastt and navigate to your dashboard.
  2. Select a project where you want to upload the XER file.
  3. Click Schedule on the left-hand menu.
  4. In the top-right corner, click Import.
  5. From the Import dropdown, choose Primavera P6.
  6. A dialogue box labeled "Import P6 .xer" will appear.
  7. Click or drag the XER file into the upload box.

Once uploaded, Mastt automatically processes the schedule data, allowing you to view, track, and manage project timelines without complex software installations. With built-in reporting and risk analysis, Mastt eliminates the need for standalone XER readers, giving project managers a faster, more accessible way to manage schedules and deliver projects efficiently.

What is the difference between XER and XML files in Primavera P6?

In Primavera P6, XER and XML files serve different purposes. XER is a proprietary format used primarily for exchanging complete project data between P6 databases, supporting multiple projects in a single file but not including baseline data.

XML, on the other hand, is an industry-standard format that supports the export and import of both project and baseline information, facilitating data exchange with other applications. However, XML imports require exclusive project access and enforce individual user security settings.
