django-admin-csv

Adds a "download csv" option to your ModelAdmin. Simply add "admin_csv" to your INSTALLED_APPS, and have your ModelAdmin extend CSVMixin like so:

from admin_csv import CSVMixin

class MyModelAdmin(CSVMixin, admin.ModelAdmin):
    list_display = ['foo', 'bar', 'baz']
    csv_fields = list_display + ['qux']
