Map two classes in runtime using column mapping information provided in a JSON file

Question

I have two Classes like this.

public class InputModel
{        
    public int studentid { get; set; }        
    public string studentname { get; set; }       
    public string studentcity { get; set; }
}

public class OutputModel
{
    public int StudentIDColumn { get; set; }
    public string StudentNameColumn { get; set; }
    public string StudentCityColumn { get; set; }
}

Now the requirement is like this:

I will receive an object of InputModel Class. From this, I need to create an object of OutputModel class.

It's simple if we use a library like AutoMapper. But the problem is, the Column-To-Column Mapping information will be supplied via a Json File like this:

{
  "studentid": "StudentIDColumn",
  "studentname": "StudentNameColumn",
  "studentcity": "StudentCityColumn"
}

Based on the JSON mapping data, I need to Map the columns in runtime and generate the Output class object.

I tried to map the two classes using Automapper. But I am not sure how to do it in runtime using the JSON file.

var MapperConfig = new MapperConfiguration(c => 
            c.CreateMap<InputCSVModel, OutputIDMModel>()
            .ForMember(dest => dest.StudentIDColumn, act => act.MapFrom(src => src.studentid))
            .ForMember(dest => dest.StudentNameColumn, act => act.MapFrom(src => src.studentname))
            .ForMember(dest => dest.StudentCityColumn, act => act.MapFrom(src => src.studentcity))
            );
            
var mapper = new Mapper(MapperConfig);                

OutputIDMModel outModel = mapper.Map<OutputIDMModel>(inputModel);

I know that it's might be possible to do this with Reflection. But is there any better approach ?
