Why Convert Primavera P6 XER to XML?
The standard .xer file format is Oracle Primavera P6's proprietary, tab-delimited relational table dump. While it has been the industry standard for decades, engineers increasingly need to convert XER to XML (specifically Primavera PMXML) for several critical reasons:
- Version Incompatibility Fixes: Importing an XER created in P6 v22 into an older P6 v18 client often fails with schema errors. P6 XML is often more forgiving or cleanly transformed between versions.
- Primavera Cloud (OPC) & Web PMIS Integration: Oracle Primavera Cloud and enterprise tools like Procore, Kahua, and Autodesk Construction Cloud frequently prefer or require XML schema imports over raw XERs.
- Fixing Corrupt Relational Tables: When an XER file becomes corrupted (such as orphaned
TASKPREDlogic rows or malformed calendar shifts), exporting or transforming to XML can purge residual database index errors. - Data Mining & Power BI Pipelines: XML is natively supported by modern ETL tools, Python libraries, and Power Query, making automated schedule reporting easier than parsing raw tab-delimited XER text.
Method 1: Native Export in Primavera P6 Professional
If you have an active Primavera P6 license, the cleanest way to convert an XER to XML is directly inside the application:
- Import the
.xerfile into your P6 database via File > Import > Proprietary (.xer). - Open the project from your Project Directory.
- Navigate to File > Export.
- Choose Primavera P6 - (XML) as the export format.
- Select whether to export attached baselines, specify the output folder, and click Finish.
Method 2: Convert XER/XML to Excel & Dashboards Without P6 Installed
What if you or your client do not have an active Oracle Primavera P6 license installed? A raw XML or XER file cannot be opened in Microsoft Excel or web browsers without severe formatting destruction.
Progress Schedulytics solves this problem completely offline. It reads both .xer and .xml exports directly from your local drive and instantly converts them into:
- A comprehensive 22-sheet Excel analytics workbook with S-curves, WBS hierarchies, and Earned Value tables.
- A single-file interactive HTML dashboard with two-way cross filtering that runs in any web browser.
- An executive PowerPoint presentation deck and Word/PDF delay report.
Parse P6 XER & XML Files 100% Offline
Generate 22-sheet Excel workbooks and interactive HTML dashboards directly from your P6 exports with zero cloud uploads and no Oracle software required.

Frequently Asked Questions
Can I open an XER file in a text editor to convert it?
Opening an XER in Notepad allows you to see the header (e.g. ERMHDR 22.12), but attempting to save or manually edit it as XML without an XML parser will result in an unreadable, unusable file.
Is it safe to use online file converter websites?
No. Free online converter sites upload your schedule data to external servers. If your schedule includes project costs, subcontractor names, defense milestones, or NDA-protected milestones, uploading to an online converter violates corporate compliance.
