Exporting data from Excel in ASP.NET MVC

Looking for guidance here - I'm not well-versed in .NET or Javascript, so I'm struggling with a task. What's the simplest method to enable a user to download a JavaScript array of objects as an Excel spreadsheet? While exporting to CSV is straightforward, I specifically require it in .xlsx format. It seems like I will need to utilize the OpenXML SDK, but there's limited beginner-friendly resources on how to tackle this. Any assistance would be greatly valued.

Answer №1

Instead of sending a direct Excel file, you can simply generate a basic HTML table and specify the correct response headers (Content-type):

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

When accessed, this will trigger Excel to open for viewing the data.

In this ASP.Net MVC tutorial, we will explore how to use ClosedXML to download files in the xlsx format.

DownloadExcelFileController

    private void DownloadExcelFile(ClosedXML.Excel.XLWorkbook workBook, string fileNameFormat)
    {

        string currentTime = DateTime.Now.ToString();

        string headerString = fileNameFormat.Replace("{0}", currentTime);
        headerString = headerString.Replace(" ", "");
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", headerString);
        using (MemoryStream memoryStream = new MemoryStream())
        {
            workBook.SaveAs(memoryStream);
            memoryStream.WriteTo(Response.OutputStream);
            memoryStream.Close();
        }
        Response.End();
    }

ClosedXML.Excel.XLWorkbook GenerateWorkBook

    public static ClosedXML.Excel.XLWorkbook GenerateWorkBook(DataTable data, string sheetName)
    {
        ClosedXML.Excel.XLWorkbook workBook = new ClosedXML.Excel.XLWorkbook();
        ClosedXML.Excel.IXLWorksheet workSheet = workBook.Worksheets.Add(data, sheetName);
        return workBook;
    }

Action Method for POST Request

    [Authorize]
    [HttpPost]
    public void ExportDataToExcel(BalanceStatementModel modelReceived)
    {

        List<FinanceEntity> rows = GetRunningBalanceDueForPractice();

        DataTable table = new DataTable();
        using (var reader = FastMember.ObjectReader.Create(rows, "ItemDescription", "EventDate", "Amount", "RunningBalanceDue"))
        {
            table.Load(reader);
        }

        ClosedXML.Excel.XLWorkbook workBook = CommonBusinessMethodHelpers.GenerateWorkBook(table, "Statement");
        string fileNameFormat = "attachment;filename=\"BalanceStatement-{0}.xlsx\"";
        DownloadExcelFile(workBook, fileNameFormat);


    }

Note: This code utilizes the FastMember library available through NuGet.
