To add a style information into XML product feed/file

I need a XML programmer to add style information for product description field in XML feed provided by supplier, and covert it to CSV file, in order to display the description neatly in online store. Also, need to include the supplier prices in the output CSV file - already in it. If you have other better ways to solve the issue, you can do it too. The product description (or Features) field is currently displayed as a paragraph instead of bullet point format due to lack of style information in the XML file. This file was converted CSV and uploaded to Shopify store. Project to start soon, need to complete ASAP. Must have good attention to the details and ensure text is formatted neatly and consistently without errors. Thank you!
