Shows how to specify exact date time parse format in JSON load options.

string templateString = "**Date:** <<[date]:\"dd MMMM yyyy\">>";
string jsonString = "{ date : \"08/24/2025\" }";
JsonDataLoadOptions jsonLoadOptions = new JsonDataLoadOptions();
jsonLoadOptions.ExactDateTimeParseFormats = new List<string> { "MM/dd/yyyy" };
JsonDataSource ds = new JsonDataSource(new MemoryStream(Encoding.UTF8.GetBytes(jsonString)), jsonLoadOptions);

ReportBuilderContext context = new ReportBuilderContext();
context.DataSources.Add(ds, "");

ReportBuilder.Create(context)
    .From(new MemoryStream(Encoding.UTF8.GetBytes(templateString)), new LoadOptions() { LoadFormat = LoadFormat.Markdown })
    .To(ArtifactsDir + "JsonDataLoadOptions.ExactDateTimeParseFormats.docx")
    .Execute();
