When uploading a project file, a Wrong Format error displays and you are not able to submit your project.
This happens if the Microsoft Office® version and file format of your project do not exactly match the expected file format.
Some ways this can happen include:
- Using Save As to change the file format or version.
- Changing the file extension or adding a file extension manually.
- Using an application other than the required version of Microsoft Office to work on your project file.
Resolution
If you changed the file format or extension, use Save As to save your project file in the correct file format and with the correct file extension.
If the error persists, you might need to download the start file again and start over.
