Online XER viewer: open .xer files in your browser
View Primavera P6 .xer schedule exports in your browser, without P6. See each project and its activities with ID, name, start, finish and duration, plus a simple timeline bar. Nothing is uploaded.
Your file is read by JavaScript on this page, on your device. It is not uploaded or sent anywhere: opening a file makes no network requests. You can even go offline after the page has loaded.
What the Windows app adds
The web viewer shows the first 1,000 activities as a table. The Windows app reads whole schedules, offline on your PC:
MPP & XER Viewer - Gantt Chart & Schedule
- Open Microsoft Project .mpp, .mpx and XML schedules as well as .xer.
- A full Gantt chart with summary bars, predecessors, link types and lag, resources and search.
- Compare two schedule versions to see what moved (summary free; full list and reports with a Compare subscription).
FAQ
Is my schedule uploaded?
No. The .xer file is read by JavaScript on this page, in your browser. The page blocks network connections; opening a file adds no requests.
What is shown?
Projects, WBS and activities from the PROJECT, PROJWBS, TASK and CALENDAR tables. Dates are actual dates where they exist, otherwise early or planned dates. Duration is the original duration in days, using the hours per day of each calendar. The schedule is not recalculated.
What are the limits?
The first 1,000 activities per project are listed (sorted by start date), with the total count. Relationships are counted but not drawn. P6 XML and .mpp files are not opened here. If names look garbled, choose the encoding the file was exported with.
