How to convert XML to Json and Json back to XML using Newtonsoft.json?

Json.NET supports converting JSON to XML and vice versa using the XmlNodeConverter.

Elements, attributes, text, comments, character data, processing instructions, namespaces, and the XML declaration are all preserved when converting between the two

SerializeXmlNode

The JsonConvert has two helper methods for converting between JSON and XML. The first is SerializeXmlNode(). This method takes an XmlNode and serializes it to JSON text.

DeserializeXmlNode

The second helper method on JsonConvert is DeserializeXmlNode(). This method takes JSON text and deserializes it into an XmlNode.

Example 1

static void Main(string[] args) {
   string xml = @"Alanhttp://www.google1.com Admin1";
   XmlDocument doc = new XmlDocument();
   doc.LoadXml(xml);
   string json = JsonConvert.SerializeXmlNode(doc);
   Console.WriteLine(json);
   Console.ReadLine();
}

Output

{"person":{"@id":"1","name":"Alan","url":"http://www.google1.com","role":"Admin1"}}

Example 2

static void Main(string[] args) {
   string json = @"{
      '?xml': {
         '@version': '1.0',
         '@standalone': 'no'
      },
      'root': {
         'person': [
            {
            '@id': '1',
            'name': 'Alan',
            'url': 'http://www.google1.com'
            },
            {
            '@id': '2',
            'name': 'Louis',
            'url': 'http://www.yahoo1.com'
            }
         ]
      }
   }";
   XmlDocument doc = (XmlDocument)JsonConvert.DeserializeXmlNode(json);
   Console.WriteLine(json);
   Console.ReadLine();
}

Output

'?xml': {
   '@version': '1.0',
   '@standalone': 'no'
},
'root': {
   'person': [
      {
      '@id': '1',
      'name': 'Alan',
      'url': 'http://www.google1.com'
      },
      {
      '@id': '2',
      'name': 'Louis',
      'url': 'http://www.yahoo1.com'
      }
   ]
}
