    PROCEDURE ConvertToJson@1240060005(VAR TempBlob@1240060000 : Record 99008535);
        VAR
          XmlDocument@1240060003 : DotNet "'System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Xml.XmlDocument";
          JsonConvert@1240060002 : DotNet "'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'.Newtonsoft.Json.JsonConvert";
          JsonText@1240060001 : Text;
          JsonFormatting@1240060004 : DotNet "'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'.Newtonsoft.Json.Formatting";
          InStr@1240060005 : InStream;
          OutStr@1240060006 : OutStream;
        BEGIN
          TempBlob.Blob.CREATEINSTREAM(InStr);
          XmlDocument := XmlDocument.XmlDocument;
          XmlDocument.Load(InStr);
          JsonText := JsonConvert.SerializeXmlNode(XmlDocument.DocumentElement,JsonFormatting.Indented,TRUE);
          TempBlob.INIT;
          TempBlob.Blob.CREATEOUTSTREAM(OutStr,TEXTENCODING::UTF8);
          OutStr.WRITETEXT(JsonText);
          //MESSAGE(JsonText);
        END;
    

    In that version, you don't have all the codeunits which handles Json, you need to copy that code from new versions, I did this for NAV 2013 R2.  You can create Xml and then covert it to Json, something like above

    You have web services available in that version. Publish some pages and you can work with them like odata. Publish a codeunit and you can pass over xml
