Secure Primavera P6 schedule comparison
Online XER Comparison Tool With No Data Upload
This Primavera P6 XER comparison tool helps planners, project controls engineers and claims teams compare a baseline or previous update against a revised programme directly in the browser. Your XER files are read locally on your device, so confidential project schedules are not uploaded to Planix Engineering or stored on a server.
How To Use The XER Comparison Tool
- Export the baseline, previous update or approved programme from Primavera P6 as an XER file.
- Export the current or revised programme as a second XER file.
- Load both files into the browser and click the comparison button.
- Review progress, activity, duration, date, logic, lag, constraint and calendar changes by WBS.
- Export the report for schedule review, progress meetings or delay analysis records.

XER Comparison FAQ
Are my Primavera P6 XER files uploaded?
No. The comparison runs locally in your browser. Your XER files are not uploaded to Planix Engineering and are not stored on a server.
Is this tool suitable for confidential project schedules?
Yes. Because the tool uses local browser processing, it is suitable for sensitive project controls workflows where corporate schedule data should not leave the user's device.
Which files are compatible?
The tool is built for Primavera P6 XER exports. For best results, compare two XER files from the same project, such as a baseline and a current update.
Does this replace Primavera P6?
No. It is a companion review tool for planners and project controls teams. Primavera P6 remains the source system for schedule creation and official updates.
