Contacts to leads...

Hi everybody :slight_smile:
I have a question !
It’s quite easy to convert a lead to contact.
Now, if i want to convert a contact in lead, is this possible ?
Why this question ?
I have a person who have import 1600 contact in the database and there are not contact but leads… So i want to correct this without exporting + deleting + importing…

So is this possible ? If so, how ?

Thanks !

So, possible or not possible ??
Thanks :slight_smile:
