.NET 5 - Json Serialization with comma as decimal separator

Is there a way to serialize a JsonResult in a controller considering the current locale? In my case when the language is set to italian I wish separator for decimal values was ',' instead of '.'.

JsonDataTable<SomeObj> res = new JsonDataTable<SomeObj>(someObjList);

return new JsonResult(res);

Here’s an example of culture-specific decimal converter - copied from here:

using System.Text.Json;
using System.Text.Json.Serialization;

public class CultureSpecificQuotedDecimalConverter : JsonConverter<decimal>
{
    public override decimal Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
    {
        if (reader.TokenType == JsonTokenType.String)
        {
            return Convert.ToDecimal(reader.GetString(),   System.Globalization.CultureInfo.GetCultureInfo("es-ES"));
        }
        else
        {
            return reader.GetInt32();
        }
    }

    //Write() not shown
}

Use like this:

using System.Text.Json;

var jsonOptions = new JsonSerializerOptions();
jsonOptions.Converters.Add(new CultureSpecificQuotedDecimalConverter());

var movie = JsonSerializer.Deserialize<Movie>(movieJson, jsonOptions);

Console.WriteLine($"Year={movie.YearReleased} Revenue={movie.Revenue}");
