In Optimizely, you can create custom reports and use the built-in reports in the admin view. The following example shows how to create a custom report of existing pages on a website and export the report to Excel using EPPlus.

Start by creating a Controller that looks like this:

namespace AlloyExample.Controllers {
  [EPiServer.PlugIn.GuiPlugIn(
    Area = EPiServer.PlugIn.PlugInArea.ReportMenu,
    Url = "~/existingpagesreport",
    Category = "Existing Pages",
    DisplayName = "Pages By PageType")]
  [Authorize(Roles = "Administrators, WebAdmins")]
  public class ExistingPagesReportController: Controller {
    public ActionResult Index() {
      return View();
    }
  }
}

This controller is a GuiPlugin, which is shown in the report menu and uses the URL /existingpagesreport. The controller is protected, so you have to be part of the administrator group to use it.

For the URL to work, add a route to it in global.asax.cs:

protected override void RegisterRoutes(RouteCollection routes) {
  base.RegisterRoutes(routes);
  routes.MapRoute(
    "ExistingPagesReport",
    "existingpagesreport/{action}",
    new {
      controller = "ExistingPagesReport", action = "Index"
    });
}

Create a simple view and ensure it displays in the report center.

Add a ViewModel with the necessary properties:

public class ExistingPagesReportViewModel {
  public IEnumerable<PageType> PageTypes {
    get;
    set;
  }
  public PageDataCollection Pages {
    get;
    set;
  }
  public string SelectedPageType {
    get;
    set;
  }
}

Create a helper class to make a request against Optimizely like this:

public static class ExistingPagesHelper {
  public static IEnumerable<PageType> GetAllPageTypes() {
    var contentTypeRepository = ServiceLocator.Current.GetInstance<IContentTypeRepository>();
    return contentTypeRepository.List().OfType<PageType>();
  }

  public static void SetPagesForPageTypeName(ExistingPagesReportViewModel model) {
    var criterias = new PropertyCriteriaCollection();
    var criteria = new PropertyCriteria();
    criteria.Condition = CompareCondition.Equal;
    criteria.Name = "PageTypeID";
    criteria.Type = PropertyDataType.PageType;
    criteria.Value = model.SelectedPageType;
    criteria.Required = true;
    criterias.Add(criteria);
    var pages = DataFactory.Instance.FindPagesWithCriteria(ContentReference.RootPage, criterias);
    model.Pages = pages;
  }
}

Update your index action to create an instance of the view model and assign all page types to it:

public ActionResult Index() {
  var model = new ExistingPagesReportViewModel {
    PageTypes = ExistingPagesHelper.GetAllPageTypes()
  };
  return View(model);
}

Create a view and add Optimizely's CSS and JavaScript to it to have the same appearance as other built-in reports in Optimizely. The complete view looks like this:

@model ExistingPagesReportViewModel

                    </table>

        document.getElementById("exportReport").onclick = function () {
            document.getElementById("doExport").value = "True";
        };
        document.getElementById("showReport").onclick = function () {
            document.getElementById("doExport").value = "False";
        };
    </script>
</body>
</html>

This code has two Submit buttons but only one form action; the JavaScript function connected to the click event on the export and search submit buttons updates a hidden value telling the controller to do an export of the data or not.

The action in the controller that handles this looks like this:

[HttpPost]
public ActionResult ListPages(FormCollection form) {
  var model = new ExistingPagesReportViewModel {
    PageTypes = ExistingPagesHelper.GetAllPageTypes(),
      SelectedPageType = form["pageType"]
  };

  ExistingPagesHelper.SetPagesForPageTypeName(model);

  var doExport = false;

  if (bool.TryParse(form["doExport"], out doExport) && doExport && model.Pages != null && model.Pages.Count > 0) {
    Export(model.Pages, System.Web.HttpContext.Current.Response);
  }

  return View("Index", model);
}

It returns the view if the export values are not true.

To export the report to Excel, use EPPlus and create a function in the same class like this:

public void Export(PageDataCollection pagesToExport, HttpResponse response) {
  using(var package = new ExcelPackage()) {
    ExcelWorksheet ws = package.Workbook.Worksheets.Add("pages");

    ws.Cells[1, 1].Value = "PageId";
    ws.Cells[1, 2].Value = "PageName";
    ws.Cells[1, 3].Value = "PageUrl";
    ws.Cells[1, 4].Value = "Published Date";

    ws.Row(1).Style.Font.Bold = true;
    ws.Row(1).Style.Locked = true;

    int row = 2;

    foreach(var page in pagesToExport) {
      ws.Cells[row, 1].Value = page.ContentLink.ID;
      ws.Cells[row, 2].Value = page.PageName;
      ws.Cells[row, 3].Value = Url.ContentUrl(page.ContentLink);
      ws.Cells[row, 4].Value = page.StartPublish.HasValue ? page.StartPublish.Value.ToString("yyyy-MM-dd HH:mm") : "Not published";

      ++row;
    }

    response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
    response.AddHeader("content-disposition", string.Format("attachment; filename=pages{0}.xlsx", DateTime.Now.ToString("yyyyMMdd")));
    response.BinaryWrite(package.GetAsByteArray());
    response.Flush();
    response.End();
  }
}
