Wiley eGrade was an online assignment and gradebook system developed by John Wiley & Sons, Inc. The gbb file extension identifies its gradebook backup files.
A gbb file contains backed-up gradebook data from Wiley eGrade. It was intended to be restored or used within that system rather than opened as a general-purpose document.
The Wiley eGrade gbb backup format is obsolete, so compatible software may no longer be available.
Open or restore a gbb file with a compatible version of Wiley eGrade. The file is not intended to be opened directly in a word processor or spreadsheet application.
Because Wiley eGrade is obsolete, a current program may not be able to open this file.
No standalone converter is known for the Wiley eGrade gbb file format.
If the file can be restored in a compatible Wiley eGrade installation, use that software's available gradebook export features to save the data in another format.
