Django call 'id' expected a number but got string

Django errors with django-import-export libraries.

I want to import data from excel to db via django admin. I use for it django-import-export, but i got Field ‘id’ expected a number but got ‘HPI’.

Excel file contains

I found answer, that I have to add exclude = (‘id’,), but it didn’t help. Also i did migrations, it didn’t help too. How to fix it and have ability to import 6 columns data from excel to db via django admin?
