CSV, XLSX (Excel), XML, and TXT. Delimiters and encodings are detected automatically— no manual configuration needed in most cases. ### Is there a file size limit? There is no hard limit imposed by the plugin. Your server’s `upload_max_filesize` and `post_max_size` PHP settings determine the maximum. Files under 50MB are recommended for smooth performance. For very large datasets, split them into multiple files. ### Can I import into custom post types? Yes. Sigma ImportX works with any registered post type — custom post types created by your theme or other plugins are listed automatically in the import configuration step. ### Does it work with WooCommerce? Basic WooCommerce product import is supported in this release. You can import simple products with standard fields. More WooCommerce-specific field support is planned. ### Can I undo an import after it runs? Yes. Every import is stored in the Import History screen. Click Rollback next to any import to reverse it completely and restore your site to its prior state. ### Can I map columns to custom fields and post meta? Yes. The field mapper lets you assign any CSV column to any registered post meta key. You can also type in a custom meta key manually if it does not already exist. ### What import modes are available? Three modes are supported: * **Create** — Always inserts new records * **Update** — Finds existing posts by ID, slug, or title and updates them * **Upsert** — Updates if a match is found; creates a new record if not ### Is WordPress multisite supported? Not in the current release. Multisite support is planned for a future version. ### Can I schedule or automate imports? Scheduled and automated imports are on the roadmap. The current release is wizard- driven. ### How are images and media handled? Featured images can be imported by providing a public URL in your data file. Full media library management is planned for a future release. ### Does it work with Yoast SEO or other SEO plugins? Yes. You can map columns to any custom field, including the meta fields used by Yoast SEO, Rank Math, or other SEO plugins. ### Is my data kept private? All processing happens locally on your server. The plugin does not send any data to external servers, does not use external analytics, and does not phone home for any reason. ### Where do I get support? * **Support Forum:** https://wordpress.org/support/plugin/sigma-importx-engine/ * **Email:** mahipatsinh.r@sigmainfo.net When contacting support, please include your WordPress version, PHP version, plugin version, and a description of the issue.
