Importing data into Wordpress?

Question

WordPress

Good afternoon!
It is necessary to import data into wp
ACF Pro plugin is supplied. Almost all posts have a gallery from this plugin. It cannot be imported, only if through WP All Import Pro (price $ 200)
The second problem is that wp has created a nesting hierarchy Category->Sub_category->Brand. That is the 3rd nesting.
This is also possible through All Import Pro.
In general, 2 problems need to be solved. Import images and import to the desired category
