Change "lastname, firstname" to "firstname lastname" Find & replace

[delgesu]

Hello all! Thanks in advance for your help - I am very grateful.

I have a large text file with names and emails which I am trying to unify so that I can add them as contacts into mailchimp. It looks like this:

"Allen Shawn" <AShawn@bennington.edu>
"Jane Austen" <spettee@verizon.net>
"Kessler, Judy" <jkessler@vno.com>
"Kipper, Judith" <jkipper@iwa.org>


......
.....

The names don't have a unified format. How do I use wildcards correctly to change everything to "Firstname Lastname"?

Thank you!

There is no way for a Find/Replace to 'know' what is a first name or a last name. That said, it appears from your data that the entries starting with the last name also have commas, whereas the others do not. In that case, you could use a wildcard Find/Replace, where:
Find = (^034)([!,^034]@), ([!^034]@)\1
Replace = \1\3 \2\1
