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.

Anyone? What is the response? I have tried exporting and Notepad++ editing the vcf file but this is clumsy and prone to errors. Also difficult to re-import without generating multiple contacts. Already enough of that problem…

I’m not aware of any other way to mass edit contacts and then reimport “other than you have already done” via exporting to a.vcf file manually.
