Identifying the data format of the JSON value to be returned
Method that returns the data format of Jsondata's key

{
if(data.Keys.Contains(key))
{
if(data[key].Keys.Contains("S")) // string
return "S";
else if(data[key].Keys.Contains("N")) // number
return "N";
else if(data[key].Keys.Contains("M")) // map
return "M";
else if(data[key].Keys.Contains("L")) // list
return "L";
else if(data[key].Keys.Contains("BOOL")) // boolean
return "BOOL";
else if(data[key].Keys.Contains("NULL")) // null
return "NULL";
else
return null;
}
else
{
return null;
}
}
Method that returns the data format of the nth value of JsonData in a list format
public static string WhichDataTypeIsIt(LitJson.JsonData data, int n)
{
if(data.IsArray)

return "S";
else if(data[n].Keys.Contains("N")) // number
return "N";
else if(data[n].Keys.Contains("M")) // map
return "M";
else if(data[n].Keys.Contains("L")) // list
return "L";
