This addon will provide an ability to download all your store products in Excel file and to add/edit/delete products using Excel File after. In other words, this is an Excel export products and Excel Import products module.
First step is to generate an excel file with products, categories and
manufacturers. Click on “Generate file” link at right bottom of the
page. Now you will see a form with ability to generate products from specific category or with specific id's. Similar functionality is available for
categories and manufacturers. Click on a generate button and excel file
will be generated for you. Filename will include a timestamp when file was generated.
Next, download this file to you computer. Change its name (however, it is not necessary). Open the file and proceed with product add/edit/delete. You can copy/paste or even your duplicate products. The only limitation is - do not edit ID column (except the first row). If you are adding a product - then just leave ID column empty. Type "d"
letter in URL column to delete product.
