Export your Sales Order as a CSV File
This tutorial will show you how to export your sales order as a CSV file. A CSV file will allow you to easily open your file in a software like Microsoft Excel, thus allowing you easily update the items in your store.
From the administration panel, go to Components > Hikashop > Configuration
Click the Files tab.
Change the CSV separator to either a comma or semicolon setting (if one setting doesn't work, try the other).
Click Save & Close at the top right hand corner.
Navigate to the product orders page which is just above the Files tab. Click on Orders > Orders
Click the Export button.
When you are prompted to save your CSV file, select a directory on your computer to save it to.
