i have metabox and WpAll-Import, but the WPAI addon is not ready. So i want to start my website and import a XML / CSV file which is zip/gzipped from Awin#com (the biggest affiliate service for Europe/USA) into metabox fields. Which tool can i use to import these files and does work with all fields ?
You can use the plugin WP All Import or any import plugin to import value to the custom fields created by Meta Box. But it only works with some simple fields like text, number, email, single_image ... not work with some complicated fields like cloneable, group, field with setting 'multiple' => true.
