Frustrated that only the paid plugins would handle my various CSV files with different fields, I decided to write this plugin vs using a throwaway import script. Hopefully this will help others facing the same problem.
Simple flow-based approach:
<ul>
<li>upload your CSV</li>
<li>check/adjust data will be imported how you imagine</li>
<li>auto-generate WordPress content from your imported data</li>
</ul>
It shouldn’t need to be much harder than that.

This plugin does not phone-home or solicit you to pay for more features. By the people, for the people!

Important notes:
<ul>
<li>
Posts and Terms Identification. During import, existing posts and terms are identified by their slugs. If a post or term with the same slug exists on the destination site, it will be updated rather than creating a duplicate entry. This applies to all supported post types and taxonomies.
</li>
<li>
Migration Order. Content should be migrated in dependency order: Terms (categories, tags etc.) before Posts, and Users before Shop Orders. The plugin does not handle automatic creation of dependent data during import to maintain data integrity.
</li>
<li>
Shop Order Numbers. By default, WooCommerce uses post IDs as order numbers. During the import process, new post IDs will be created, leading to different order numbers. To preserve order numbers, ensure that both the source and destination sites use plugin or configuration that do not depend on post IDs for order numbering.
</li>
<li>
Downloadable Products. Downloadable files linked to Products can only be migrated if they are hosted on the source domain and accessible via direct URLs. Files that are protected or stored outside the source domain cannot be transferred.
</li>
</ul>
