Why has my filename changed from comma to ^J

Why has my filename changed from comma to ^J

When saving files to your personal OneDrive, certain characters are automatically renamed by Office apps, including Word, Excel and PowerPoint.

From: 
Filename with comma

To:
Filename without comma

  • Filenames that contain , are changed to ^J

  • Filenames that contain # are changed to ^N

  • Filenames that contain & are changed to ^0

How do I prevent Office apps from renaming my files in OneDrive?

Ensure that you do not use invalid or restricted characters in filenames, such as , # " * : < > ? / \ | 

Read the full list of Invalid file names and file types in OneDrive, OneDrive for Business, and SharePoint.

Sometimes, OneDrive can rename it for you. In those cases, just select the Rename button in the notification you receive. Learn more about When OneDrive renames items with invalid characters.

Why can't I share files with changed filenames?

If you shared a filename that contained invalid characters and was then renamed, the people you shared the file with are unable access it because the filename has changed. To resolve this:

  1. Rename the file. Ensure that you do not use invalid or restricted characters in filenames, such as , # " * : < > ? / \ |

  2. Share the renamed file again. Learn more about sharing OneDrive files and folders.
