In the “Product data update” app the user has several options for the mass data maintenance to maintain larger bulks of product data. Firstly, there is the “Import” tab which allows you to import larger bulks of product data via .xslx or .csv files. In the “Excel” tab you can edit product data as in a speadsheet software. And you can paste larger bulks of data that were copied from a spreadsheet software into the product data table. Furthermore, there is the tab “Translation-Export” which allows you to export product data of a selection of products to have them translated. After the translation was made, you can reimport the translated product data in the “Translation-Import” tab. And there is the “Asynchronous bulk updates” tab where you can update a large number of attributes for a great amount of products without loading the respective product datasets first.
