Currently, the imports to update custom fields allow the school to update the custom fields in bulk but we can't enter null values. It would be helpful not to need to submit a data request to have the field cleared out.
Couple of scenarios where this would be really useful:
Custom field containing a class name (e.g. 1st Grade A, 1st Grade B, etc..). Need to clear out this custom field for all departing students at the end of the year.
Email address field. We provide school email addresses to students in 3rd-8th grades. Need to clear them out when the student leaves of graduates as they are no longer valid.
Good news! This is now possible on several imports. If you use a ^ in the field it will remove that data.
