                  \n
                • upload_max_filesize<\/code> \u2014 64M or higher<\/li>\n
                • post_max_size<\/code> \u2014 64M or higher<\/li>\n
                • max_execution_time<\/code> \u2014 300 seconds or higher<\/li>\n
                • memory_limit<\/code> \u2014 256M or higher<\/li>\n<\/ul>\n\n

                  Contact your hosting provider if you need help adjusting these values.<\/p>\n\n\n

                  \n

                  What file formats are supported?<\/h3><\/dt>\n

                  CSV, XLSX (Excel), XML, and TXT. Delimiters and encodings are detected automatically \u2014 no manual configuration needed in most cases.<\/p><\/dd>\n

                  Is there a file size limit?<\/h3><\/dt>\n

                  There is no hard limit imposed by the plugin. Your server's upload_max_filesize<\/code> and post_max_size<\/code> PHP settings determine the maximum. Files under 50MB are recommended for smooth performance. For very large datasets, split them into multiple files.<\/p><\/dd>\n

                  Can I import into custom post types?<\/h3><\/dt>\n

                  Yes. Sigma ImportX works with any registered post type \u2014 custom post types created by your theme or other plugins are listed automatically in the import configuration step.<\/p><\/dd>\n

                  Does it work with WooCommerce?<\/h3><\/dt>\n

                  Basic WooCommerce product import is supported in this release. You can import simple products with standard fields. More WooCommerce-specific field support is planned.<\/p><\/dd>\n

                  Can I undo an import after it runs?<\/h3><\/dt>\n

                  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.<\/p><\/dd>\n

                  Can I map columns to custom fields and post meta?<\/h3><\/dt>\n

                  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.<\/p><\/dd>\n

                  What import modes are available?<\/h3><\/dt>\n

                  Three modes are supported:<\/p>\n\n

                    \n
                  • Create<\/strong> \u2014 Always inserts new records<\/li>\n
                  • Update<\/strong> \u2014 Finds existing posts by ID, slug, or title and updates them<\/li>\n
                  • Upsert<\/strong> \u2014 Updates if a match is found; creates a new record if not<\/li>\n<\/ul><\/dd>\n

                    Is WordPress multisite supported?<\/h3><\/dt>\n

                    Not in the current release. Multisite support is planned for a future version.<\/p><\/dd>\n

                    Can I schedule or automate imports?<\/h3><\/dt>\n

                    Scheduled and automated imports are on the roadmap. The current release is wizard-driven.<\/p><\/dd>\n

                    How are images and media handled?<\/h3><\/dt>\n

                    Featured images can be imported by providing a public URL in your data file. Full media library management is planned for a future release.<\/p><\/dd>\n

                    Does it work with Yoast SEO or other SEO plugins?<\/h3><\/dt>\n

                    Yes. You can map columns to any custom field, including the meta fields used by Yoast SEO, Rank Math, or other SEO plugins.<\/p><\/dd>\n

                    Is my data kept private?<\/h3><\/dt>\n

                    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.<\/p><\/dd>\n
