Working with Primavera P6 XER files can take unnecessary time, especially in two common situations.
If you are handling a claim, reviewing multiple updates, or preparing for bulk import, you may receive many XER files. Importing and managing them one by one can be slow and frustrating.
On the other hand, sometimes you receive one combined XER file that contains multiple projects, while you only need one project for review, comparison, or schedule checks using tools such as Plannex Excel Tool.
To solve this, I created XER Fusion.
What is XER Fusion?
XER Fusion is a simple tool designed to help you handle Primavera P6 XER files in an easier way.
It provides two main functions:
1. Merge XER Files
Combine multiple XER files into one file.
This is useful when:
- you have many XERs for a claim or record review
- you want to prepare one combined file for import
- you want to save time when dealing with many schedules
2. Split Combined XER
Split one combined XER file into separate project XER files.
This is useful when:
- you receive one XER containing multiple projects
- you need to isolate only one project
- you want to use a single project file for comparison, schedule checks, or further analysis
Available as Online and Desktop Tool
XER Fusion is available in two versions:
- Online tool
- Desktop tool
Important Note About the Online Version
The online version works fully client-side.
That means:
- your files stay in your browser
- no XER files are uploaded to the server
- no XER files are stored
- no XER files are recorded
This makes it practical for professionals who want a quick and simple solution while keeping file handling local.
Why XER Fusion Matters
XER Fusion helps reduce manual work in common planning and project controls tasks.
Instead of spending time on repetitive file handling, you can quickly:
- merge multiple XER files into one
- split one combined XER into separate project files
- prepare files for review, import, comparison, and schedule checking
Final Note
If you work with Primavera P6 schedules, claims, delay analysis, or schedule review, XER Fusion is built to make this process easier and faster.
