VM Mass Update's main focus is allowing for quick mass value updating of all major product fields, such as price, stock units, category, publishing state, and many more. Increasing your products prices by 10%, for example, is a matter of seconds, even for thousands of products.
The other strong features of VM Mass Update are powerful import/export functions for products. You are able to quickly import/update products from CSV files, or otherwise automatically create products by uploading a collection of product images. The export features allow you to export your product data to CSV, Excel, PDF and HTML formats.
VM Mass Update is currently compatible with Joomla! 1.5, 1.7, 2.5 and VirtueMart 1.1 & 2.0.
