About XER
Oracle's Primavera P6 schedules big projects, like plants, railways, towers and refineries, often in thousands of activities. It's sold to companies by the seat, so a schedule reaches everyone else as an XER, the file P6 exports and imports.
An XER is text: P6's tables one after another, each row a line of values split by tabs. It holds the project, its WBS, the activities with their dates and float, the relationships, resources and assignments, and the calendars, and one file can hold several projects.
Filepeek reads it in your browser with a reader of its own. The activities open in their WBS with their IDs, durations, dates, % complete, predecessors and resources, and their bars run along a timeline beside them: milestones as diamonds, relationships with their lags, the critical path in coral and the data date as a dashed line. Resources and Calendars have tabs of their own, and Export saves CSV, Excel, Project XML, or the chart as PDF or PNG.

Questions
How do I open an XER file without Primavera P6?
Drop it on this page or press Peek an XER. It opens as its Gantt chart in your browser, on Windows, a Mac, an iPhone or Android, with nothing to install and no P6 license.
How do I convert XER to Excel or Microsoft Project?
Open it, choose Export, then Save the activities as CSV, Save the activities and resources as Excel, or Save as Project XML, which Microsoft Project, ProjectLibre and GanttProject open.
Which activities are critical?
Those P6's last schedule left with no more total float than the project counts as critical, as long as they aren't finished. They're coral, and so are the WBS bands that hold them.
What if it holds several projects?
The project P6 exported first shows, and a note above the chart says how many the file holds.
Can I edit it?
Filepeek only shows it. Save it as Project XML to work on it in ProjectLibre or GanttProject, which are free, or in Project itself.
