how do i get a list of names that doesnt have a userName, to another sheet in google sheets

I am not sure how to get the list of names from a column that has an adjacent empty column to another sheet.
the names with blank userNames i want to import to sheet13

names imported to sheet13

>Solution :

You can use FILTER() function.

 =FILTER(B2:B,C2:C="")

If you want to filter from other sheet then just use sheet name before range like

=FILTER('Copyoftest'!B2:B,'Copyoftest'!C2:C="")

You can also use QUERY() function like-

=QUERY('Copyoftest'!B2:C,"select B where C is null",0)
