Hello! I am attempting to move data from one field to another. In my data, I have a PO box field, but that field contains addresses and other data that does not belong. How can I set up the formula to filter that information out and place into the correct field?

As you can see in the photo, the "18 Main Street" would be data that would go into the "Address" field. The "University of Southern California" is data that would go into the "Vendor Notes" field. Is there a formula that will do all those actions in one?

See the fields above.
Thank you in advance for your help!
