Open .xer Files in the Browser
Upload a Primavera P6 .xer file directly. The upload is encrypted, the file is parsed in seconds, and it stays private to your account.
Bring Your XER Schedules to the Cloud
ScheduleReader Online is a browser-based XER viewer. Upload a .xer file and it opens in seconds with the Gantt chart, WBS hierarchy and critical path already in place.
What you can do
What You Can Do in an Online XER Viewer
Upload a .xer file and work with it in the browser, without installing anything.
Interactive Gantt Chart
An interactive Gantt chart with timescale controls and relationship lines, so you can see the full picture at a glance.
Filters, Groups and Sorting
Find any activity by name, code or date. Multi-column sort, grouped views and instant search across every activity field.
WBS Breakdown View
Expand the WBS hierarchy and collapse to the level you need, then isolate a work package, a discipline or a contractor scope.
Saved Views per Version
Save filters, baselines and WBS color schemes per schedule version, so every reviewer opens the file in the view they expect.
Progress Updates
Mark activities complete, adjust remaining durations and record progress notes without a P6 seat. The original .xer file is never modified.

FAQ
Everything You Need to Know About Opening XER Files
How Do I Open a .xer File Online?
Upload the .xer file to ScheduleReader Online and it opens in your browser. The file is parsed in seconds and you can view the Gantt chart, the WBS hierarchy and the activity table straight away. There is nothing to install.
Do I Need Primavera P6 Installed?
No. ScheduleReader Online opens Primavera P6 .xer exports directly in the browser. You do not need P6 installed, licensed or running anywhere. Just upload the file you already have.
Which File Formats Are Supported?
Primavera P6 .xer exports only. Unlike the desktop apps, the online viewer does not open P6 .xml files, and Microsoft Project files are not supported either.
How Is My File Handled?
Your file is uploaded to the processing service over an encrypted connection so it can be parsed. It uses the same MPXJ engine the desktop tools use, and files are stored encrypted at rest in your account.
Can I Export the Gantt for a Status Report?
Yes. Save your filters, baselines and WBS color schemes per schedule version, then export the Gantt as a multi-page PDF, or as PNG and SVG, to drop straight into a report.
Can I Delete My Files, and What Happens After the Trial?
You can delete any version at any time from the Schedules page. The public demo and any schedules you have already uploaded are available without a subscription. The Professional plan unlocks uploads, private Gantt views, baselines, saved filters and exports, and you can cancel any time from the Stripe customer portal.
