Does exactly what it says, but not very polished. You will need to work around its glitches:
Importing from Classroom:
1. You HAVE to put text in a column header for it let you choose that column. If you only put in a column of email addresses only column A appears in the pop-up
2. The assignment title you just put into the header of column 2 doesn't get pulled in as the Assignment title (so lots of flicking back and forth between Classroom and Sheets, which is what we're trying to avoid)
Exporting to Classroom:
1. You can only choose increments of 10 (ie 10, 20, 30 ... 100) for the maximum grade. My IGCSE past paper marks are all out of 200, my self-written tests can be anything, so I have to go back in and edit them :/
2. You MUST put something in each cell, even if it's 0, since the script hangs on empty cells (rather than skipping them, since the student may have been absent for that test, or left, or arrived since the test was set).
