WP All Import can import to categories, tags, and any custom taxonomies associated with the post type you are importing. When importing to a Post, the default taxonomies are Categories and Tags.

In the example below, we are importing data to a real estate theme with custom taxonomies for property locations, price ranges, and more.

To import taxonomy terms into existing ones, we recommend using the existing term slug instead of the name. By using the term slug, you will avoid creating a duplicate taxonomy term.

That said, WP All Import uses the built-in function term_exists to match existing taxonomy terms, which means it can match using either term ID, slug, or name.
