Gradebook export
From MoodleDocs
Introduction
The Moodle 1.9 gradebook provides support for plug-in export modules. Moodle includes several export modules in the release. However, you may need the gradebook data formatted differently than the provided modules. Two primary uses for the gradebook export is to provide a teacher with a copy of their gradebook at certain point in time and to provide assessment data that can be loaded into a different district software application without having to reenter that data.
