How do I set Oracle PIM "Formatted Description" CLOB to null via FBDI

Summary:Oracle SCM Product “item import” FBDI / csv EGP_SYSTEM_ITEMS_INTERFACE/ItemImportTemplate.xlsm

the situation is when the source system value is blanked out, we need to clear out the Oracle field.

Using "#NULL" to clear out "Formatted Description" (PIM/Manage Items overview tab) is not working. What happens is the table field contains "#NULL" as well as the GUI instead of clearing it out. Suggestion from consultant said to try <div></div>. That worked, at least from a GUI perspective the field was cleared, but then that value was stored in the table column.

How do we clear out the CLOB field and NOT have the value stored in the table? Solution must be using the fbdi csv please. This would be column FE in the fbdi doc.
