How to mass update contacts?

How to mass update all my contacts and delete the “email display as” field instead of single edit every contact?

Because when email display-as is empty, the full name will be displayed when I write an email but by default when I add a new contact, the display as field will be filled with the email address itself and then displayed twice. Now I have a lot.

With stored email address:

"[email protected]" <[email protected]>

and when email display as is empty:

"A xxxxx" <[email protected]>

It would be better when I add a contact from an email the “email display as” would be empty by default and not filled with the email address.
