Introduction

I want to convert Json file to xml file. Many code available on internet you can applied easily and It is working fine. but sometime we got an error. 

"The ' ' character, hexadecimal value 0x20, cannot be included in a name."

Solution

Sol 1- jsonStr.Replace(“ “,””);

              

With this solution, String does not contain any space.

Sol 2-

var objJson = JArray.Parse(jsonString);

 foreach (var fix in (from property in objJson.Descendants().OfType<JProperty>()

         let newName = XmlConvert.EncodeLocalName(property.Name.Replace(" ", ""))

         where newName != property.Name

               select new { Old = property, New = new JProperty(newName, property.Value) })          .ToList())

         {

            fix.Old.Replace(fix.New);

         }

                XmlDocument xdoc = JsonConvert.DeserializeXmlNode("{\"root\":" + objJson.ToString() + "}", "root");
