Content Uploader Pro
Formerly known as the Excel Uploader. The Content Uploader Pro allows you to upload Excel sheets to batch create:
This means that each row from your Excel sheet will create one new article/item on your site. Website creators who want to populate a site quickly by importing existing articles, will find this particularly useful as it eliminates a time consuming, manual process. Furthermore you can update existing articles by downloading the existing ones and reuploading them with supplying their ID to the Content Uploader. The same way you can upload your Joomfish translations for all articles like that from an Excel sheet.
Have a look at our site for the documentation and features comparison between the pro and the free version.
All Excel spreadsheet types are supported (xlsx, xls, csv, ooc, zip and more).
