What you can do in an
online XER viewer

A browser based XER viewer that shows a Primavera P6 schedule the way the planner built it, without the database.

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.

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. Isolate a work package, a discipline or a contractor’s scope and see the activities and dates behind it

Saved views per version

Save your filters, baselines and WBS colour 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.
