Account Report - won't show Parent Account Id

Account Report - won't show Parent Account Id

I created a basic Account report called Parent account mapping - just to show Account Name and Parent Account.


When the .csv file gets generated it displays



I was assuming that the second ACCOUNTID would show the account id of the Parent account.  But obviously it doesn't.  It just shows the main account.

Is there any way to get a report to display the Parent's Account Id?
