Frequently Asked Questions About Opening XER Files
Everything schedulers and project stakeholders ask before they open a Primavera P6 schedule.
How do I open a .XER file without Primavera P6?
An .XER file is a data export, not a document you can read in a text editor. Use a standalone XER viewer: ScheduleReader reads the exported .xer or P6 XML file directly and never connects to a Primavera P6 database, so no Oracle license is required on the machine that opens it. Activities, the WBS hierarchy, relationships, resources and calendars render as soon as the file loads.
Can I open .XER files online in a browser?
Yes. ScheduleReader Online runs entirely in the browser, so you can upload a .xer file and work with the Gantt, the WBS hierarchy and the activity table without installing anything. The file is parsed by the same engine the desktop application uses, so the schedule you see online matches the one you see on Windows or Mac.
What is the difference between .XER and P6 XML?
.xer is Oracle’s proprietary export format. It packs a project’s tables into a single file, which is why it is the format most schedulers exchange by email. P6 XML is the XML-based exchange format, and it is the better choice when you need to move data between P6 databases or merge projects. ScheduleReader opens both, and you can open either format without a P6 license.
What is an .XER file?
An .XER file is the export format produced by Oracle Primavera P6. It contains a project’s complete dataset — activities, WBS hierarchy, relationships, constraints, resources, calendars and activity codes — in one file that can be shared without giving the recipient access to a P6 database.
Does a large schedule slow it down?
No. Because ScheduleReader works on the exported file rather than a live database connection, complex schedules open in seconds. Schedulers regularly report opening even the largest projects in under three seconds, and there is no database round-trip to wait on.
Can I compare two versions of a schedule, or compare against a baseline?
Yes. ScheduleReader supports baselines, so you can hold a committed plan alongside the live schedule and see date, duration and float slippage. Project controls teams use this to show what has moved since the last revision, and to separate real progress from re-sequencing.
Can I check a schedule’s quality before I submit it?
Yes. ScheduleReader runs DCMA 14-point schedule quality checks and flags the defects that cause submissions to be rejected — open ends, missing logic, negative lags, hard constraints and high-float activities. You can review the findings and export a PDF audit report for the project director, owner or client.
Is my schedule data secure when I open it online?
Files uploaded to ScheduleReader Online are transferred over an encrypted connection and stored encrypted at rest in your own account. You can delete any version at any time. The desktop application never uploads anything — it reads the file locally on your machine.
Does it work on Windows and Mac, or only in the browser?
All three. ScheduleReader runs as a native application on Windows and on macOS, and ScheduleReader Online runs in the browser with no installation. The interface is consistent across them, so a scheduler on Windows, a project manager on a Mac and a stakeholder on a browser all see the same schedule the same way.
