Multiple non-primary emails import

Hello all,

I am trying to import multiple non primary emails to our system.
The csv file has the following format:

Non Primary E-mails
sample1@test.com; sample2@test.com
Sample3@test.com; sample4@test.com
Sample5@test.com; sample6@test.com

But the import cannot be completed as errors occur due to the invalid values of the emails “;sample2@test.com”.
How could I fix this issue? Is there any other way to import multiple non-primary emails?

Thank you in advance,
Pagibe.
