Open an XER file. Understand the schedule.
An XER export contains far more than a list of activity names. SEQNCS turns Primavera P6 schedule data into an interactive view you can navigate, filter and inspect without starting a full P6 editing session.
No account required for FREE tools. Schedule files are parsed in your browser.
What does an XER viewer show?
A Primavera P6 XER file is a structured project schedule export. A useful reader must connect activity identifiers, names, dates, WBS and logic rather than display the file as plain text.
SEQNCS Schedule Explorer parses the XER in your browser and presents a navigable Gantt view of the current schedule. It is designed for review, not for changing the original P6 programme.
- Browse the schedule with WBS or available Activity Code grouping.
- Search for activity IDs, descriptions and schedule dates.
- Inspect relationships and expand from an activity to its context.
Primavera P6 Viewer: from Gantt overview to activity detail
For progress meetings and planning reviews, the P6 Viewer gives you a navigable view of the Primavera P6 schedule rather than an editing interface. Start with a fitted Gantt overview and zoom into months, weeks or individual days.
Follow WBS branches, use available Activity Codes to group work packages, find milestones and inspect logic relationships. Grouping and colours help you discuss the programme with project managers and construction teams without changing the source file.
- Fit the loaded schedule to the available viewer width.
- Switch between WBS and available Activity Code groupings.
- Use the configurable PDF export for a shareable schedule view.
When a viewer is not enough
Need to assess logic quality? Run the free DCMA Schedule Check. Need to evaluate two revisions? Use Schedule Explorer COMPARE to look at additions, removals, milestone movement and logic changes.
When the decision requires programme editing, rescheduling or resource levelling, the source planning software remains the appropriate place to make those changes.
- Use VIEW to understand one schedule.
- Use COMPARE to investigate revisions.
- Use Schedule Check to evaluate schedule health.

Frequently asked questions.
Do I need Primavera P6 installed to view an XER?
No. The SEQNCS viewer runs in a web browser and reads supported Primavera P6 XER exports.
Is this also a free Primavera P6 Viewer?
Yes. XER Viewer and Primavera P6 Viewer describe the same SEQNCS Schedule Explorer VIEW tool. Open supported Primavera P6 XER exports directly in your browser; no P6 installation or SEQNCS account is required for FREE viewing.
Can I edit the P6 schedule in SEQNCS?
Schedule Explorer is for viewing and comparing. It does not replace Primavera P6 as the system used to edit and recalculate a project schedule.
Does the viewer show logic links?
Yes. Schedule Explorer provides activity relationship information when it is present in the loaded XER.
Can I group the P6 schedule by WBS and Activity Codes?
Yes. Explore schedules by WBS and by available Activity Codes included in the uploaded XER, then navigate the dates and relationships in the Gantt timeline.
Where does my XER data go?
XER parsing and schedule analysis are performed in the browser. See the published Privacy and Methodology pages for the complete product disclosures.
