Open, inspect, and share project schedules from XER, MPP, and XML formats without requiring expensive Primavera P6 or Microsoft Project licenses. Fast, standalone, and built for schedulers.
Explore the powerful capabilities that make XER Reader the premier standalone schedule viewer for engineering, construction, and capital project teams.
Break software and license silos across project stakeholders. XER Reader directly opens Oracle Primavera P6 (.xer, P6 XML) and Microsoft Project (.mpp, .mpx, XML) schedules in seconds. Engineered for high-speed performance, it parses and renders massive project schedules with 50,000+ activities smoothly without requiring Primavera or Project installations.
Navigate complex schedules with unprecedented clarity. The left activity table and right Gantt timeline share identical rows and scroll in perfect synchronicity. Smoothly zoom the timescale from multi-year macro summaries down to individual shifts, and customize relationship dependency arrows to suit your review workflow.
Build your own Gantt bar definitions using an extensible 3-part design system: Filter (logical conditions per activity) + Time Scale (named start/finish date field pairs) + Shape Style (Start endpoint, Middle body, and End boundary shapes and colors). Tailor appearance for different stakeholders, disciplines, and contractor tiers.
Eliminate visual clutter and focus on what matters. Slide out the dedicated WBS Filter Drawer to instantly isolate specific work packages, disciplines, or sub-deliverables. Select any task to reveal the comprehensive 4-tab inspector panel without obscuring your schedule canvas.
A single schedule view cannot answer every project question. XER Reader equips project teams with six purpose-built workspace perspectives to analyze every dimension of project delivery:
Track schedule variance and monitor progress against committed targets with XerReader's dedicated Baseline Manager. Effortlessly assign up to four baseline tiers (Project, Primary, Secondary, and Tertiary) to any active schedule using intuitive drag-and-drop, compare multiple revisions simultaneously, and visualize baseline bars alongside live activities in the interactive Gantt chart.
Ensure project schedule validity before submitting to project directors, owners, or government agencies. Run 18+ automated diagnostic checks following the industry-standard Defense Contract Management Agency (DCMA) 14-point guidelines to identify logic defects, missing predecessors, and unrealistic float before they trigger costly delays.
Save your entire workspace configuration (column order, column alias names, column filters, grouping hierarchies, expanded state of the tree, Gantt settings, screen size, and theme) into custom named layouts you can instantly recall, apply, or update across any schedule.
Query schedule tables directly with SQL speed. Import external CSV or Excel spreadsheets as tables to join cost, payroll, or procurement data against project activities without leaving the viewer.
Eliminate friction between teams using different project tools. Open any Oracle Primavera P6 XER or XML file and generate a native Microsoft Project (.mpp) file directly, or export active schedules into clean CSV and Excel spreadsheets for commercial modeling, estimator handoffs, and cloud enterprise data lakes.
Produce crystal-clear, presentation-ready vector PDF schedule printouts for project teams, boardrooms, and client meetings. Dedicated vector rendering ensures all typography, table columns, Gantt bars, and dependency lines maintain razor-sharp clarity without pixelation.
Share live, interactive project schedules with owners, clients, and subcontractors via zero-install web links. Recipients explore Gantt timelines, inspect task details, and filter WBS trees directly in any modern browser without installing desktop software or acquiring expensive licenses.
Pipe live schedule database tables directly into enterprise reporting dashboards without tedious manual CSV re-exports. Publish authenticated cloud API endpoints with secure token governance, execute custom SQL queries on the fly, and automate dashboard data sync effortlessly.

Instantly isolate critical tasks and structure complex schedules with Excel-like speed and flexibility. Every column header in the Activity table features built-in AutoFilter controls with multi-select checkboxes, custom expression rules, and date trees. Pair filtering with the dynamic Group Manager to organize activities by WBS, Activity Codes (discipline, area, contractor), or date periods, complete with automatic roll-up summaries, custom color banding, and multi-level tree expansion.
Work comfortably in any lighting environment, from sunny job site trailers to multi-monitor engineering offices. Seamlessly switch between crisp Light Mode, sleek Dark Mode, or automatic operating system theme matching. Fine-tune your workspace with the dynamic screen scaling slider to adjust UI density, font sizes, and row heights for perfect readability on high-DPI 4K/5K monitors and compact laptop displays alike.
Experience zero friction and zero learning curve across your organization. Whether running native desktop on Windows or macOS, or launching the zero-install web edition, you get a 100% identical user interface: same ribbon tools, identical table columns, matching Gantt interactions, and consistent keyboard shortcuts. Even run XER Reader directly in mobile device browsers on smartphones and tablets for instant field access anywhere on the construction site.
Bridge the communication gap between certified planners and broader project stakeholders.
Schedulers often spend hours each week generating static PDF reports for various teams. Give your team direct access to interactive schedules so you can focus on schedule integrity.
Stop squinting at static, outdated PDFs. Stakeholders can now filter, search, inspect tasks, and verify milestone dependencies on their own terms without expensive license fees.
Equipping field engineers, supervisors, and subcontractors with full Primavera licenses is impractical. XER Reader gives them simple, fast, and clear task visibility anywhere.
Insights and guides to help you get the most out of XER Reader.
Decide which columns and which grouping every new file opens with, per file format, and rename the four baseline tags.
Choose the unit durations and units are reported in, decide whether the calendar or a fixed conversion supplies the hours, and set the abbreviations.
Set the application to follow the system theme or force light or dark, and scale the whole interface between 80 and 170 percent.
