Sigma ImportX Engine is a professional data import plugin for WordPress. Whether you’re migrating from another CMS, importing a product catalog, or doing a bulk content upload, Sigma ImportX handles it reliably through an intuitive step-by-step wizard.

Upload your file, map your columns to WordPress fields, configure your settings, and import — all without writing a single line of code. Every import is logged and can be rolled back instantly if something goes wrong.

Who Is This For?

• E-commerce Operators — Import product catalogs including custom fields and metadata

How It Works

The 5-step import wizard guides you through the entire process:

1. Upload — Drag and drop or browse to select your CSV, XLSX, XML, or TXT file
2. Preview — Review a sample of your data and confirm it was parsed correctly
3. Map Fields — Assign each column to a WordPress field or custom meta key
4. Configure — Choose post type, import mode, and post status
5. Import — Watch the progress in real time and review the detailed results log

When the import is done, it is recorded in Import History. If anything looks wrong, roll it back with one click.
