在ASP.NET MVC中导出Excel电子表格

Question

Can anyone point me in the right direction? I'm not very .NET or Javascript savvy so this is a bit too difficult for me. What's the easiest way to let a user download a Javascript array of objects in the form of an Excel spreadsheet? I know exporting it to CSV is the easiest way but I really need to export it in proper .xlsx format. As far as I understand, I will need to use the OpenXML sdk, but there's not much info (at least noob-friendly info) on how to actually approach it. Any help is appreciated.

Answer 1

You can also just output a basic HTML table and set the appropriate response headers (Content-type):

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

This will prompt the user to open Excel to view the file.

Answer 2

 $("[id$=myButtonControlID]").click(function(e) { window.open('data:application/vnd.ms-excel,' + encodeURIComponent( $('div[id$=divTableDataHolder]').html())); e.preventDefault(); }); 

 table { border: 1px solid black; } th { border: 1px solid black; padding: 5px; background-color:skyblue; color: white; } td { border: 1px solid black; padding: 5px; color: green; } 

 <button id="myButtonControlID">Export Table data into Excel</button> <div id="divTableDataHolder"> <table> <tr><th>ColumnOne </th><th>ColumnTwo</th></tr> <tr> <td>row1ColValue1</td><td>row1ColValue2</td> </tr> <tr> <td>row2ColValue1</td><td>row2ColValue2</td> </tr> </table> </div>

Folloiwng is a ClosedXML approach in ASP.Net MVC. It will help download files as xlsx

GenerateExcelInvoiceController

    private void GenerateExcelInvoiceController(ClosedXML.Excel.XLWorkbook workBook, string formtFileName)
    {

        string currentTime = DateTime.Now.ToString();

        string headerString = formtFileName.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 GetWorkBook

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

Controller Action for POST

    [Authorize]
    [HttpPost]
    public void PracticeList(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.GetWorkBook(table, "Statement");
        string formtFileName = "attachment;filename=\"BalanceStatement-{0}.xlsx\"";
        GenerateExcelInvoiceController(workBook, formtFileName);


    }

Note: It uses FastMember librabry available via NuGet.
