Receive "Incorrect datetime value: 'NULL' for column..." when importing Excel into database

Hi all,

I am loading thousands of rows in a sync-enabled record through Import Excel into database plugin.

How to deal with errors from process execution when trying to import date/time Excel columns with no current date (or Null). Is it any alternative rather than inserting a default date/time value? 

Thank you for any suggestion,
