I am looking for recommendation on the best CSV / Excel custom post type / custom field importer for WordPress. I would like support, as this will be used primarily by a client with little development experience. I have found 2 that I am considering and am interested in templates for import, along with file checking / data validation. The 2 plugins I’m considering are WP All Import (http://www.wpallimport.com/) and WP Ultimate CSV Importer Pro (http://www.smackcoders.com/wp-ultimate-csv-importer-pro.html). Has anyone used these, experienced support, etc?? Right now I am using CSV Importer (http://wordpress.org/plugins/csv-importer/) – which works well, but not for end users / clients.
