Question details

The user needs to transfer a Project Online project and save it locally as an MPP file rather than exporting it to Excel.

How to Save a Project Online Project as an MPP File
Product
Microsoft Project Online
Device & OS
not provided
Scenario
Transferring or backing up a project from Project Online to a local desktop format.
Observed behavior
The user is looking for a way to save the project directly as an MPP file instead of using the default Excel export functionality.
Before you start

Ensure you have the Microsoft Project desktop client installed and fully updated, as you will need it to open and export projects directly from the Project Center.

Solution 1Recommended

Export Project Online to MPP via Desktop Client

Open your project from the Project Center directly into the desktop client to access the 'Save Project as File' option.

Project Online does not natively allow direct MPP downloads from the web interface. You must use the Microsoft Project desktop application to bridge this gap.

1
Open Project Center

Log into Project Online and navigate to the Project Center where your projects are listed.

2
Launch in Desktop Client

Select the project you wish to save, then click 'Open in Microsoft Project' from the ribbon interface.

3
Navigate to Export Options

Once the project loads in the Microsoft Project desktop client, click on the 'File' tab in the top-left corner and select 'Export'.

4
Save as MPP File

Click on 'Save Project as File', choose the standard MPP format, and select a local destination on your computer to save the file.

Export Project Online to MPP via Desktop Client
Export Complete: Your Project Online data is now successfully saved as an offline MPP file for local use.

Frequently Asked Questions

Can I open an MPP file without having Microsoft Project installed?

To natively open and edit an MPP file, you need Microsoft Project. However, you can use third-party MPP viewer applications or import the file into compatible project management platforms if you do not have a Project license.

Why is the 'Open in Microsoft Project' button missing in Project Center?

This usually occurs if you do not have the appropriate Project Plan license assigned to your account, or if the Microsoft Project desktop client is not correctly installed and associated with web protocols on your PC.

Can I convert an MPP file into an Excel spreadsheet later?

Yes. Once you have the file open in the Microsoft Project desktop client, you can go to File > Export > Save Project as File, and then select the Excel Workbook (*.xlsx) format to export your task data into a spreadsheet.
