The XML to JSON to Server appplication takes a XML file containing 8k+ products and its data such as product name, description, price, URL location, etc. converts it to JSON format and uploads the JSON file to the server.
During this time period in my former job, the only way to obtain product data and customize the company's Website was through a XML file the Content Manager System (CMS) produced. If one is familiar with the size of a XML file containing 8k+ products, he or she knows the file can be large and it was so.
Moreover, if one is familiar with a CMS, he or she knows that there are limitations in which the user/developr cannot access certain services such as direct access to the database. One needed to be creative to "work around" the CMS.
