  • Thanks vishvas and Nishath,

    Sorry but i forgot to mention that i am not expecting Microsoft excel to be installed on the machine. So i  will not be able to use any of the Interop solutions i guess.

    @Nshanth :I am looking for general approach for exporting to Excel. The Approach you mentioned is for converting from gridview to excel

  • Agalo,

    Oh!So you need something which would do exporting of data to excel even when excel is not installed. In addition to what NeedleSK has suggested, there are some good component like excelxmlwriter http://www.carlosag.net/Tools/ExcelXmlWriter/

    And visit http://www.aneef.net/2008/07/25/create-excel-sheets-programmatically-with-c-without-installing-excel/ for demonstration of such usage of writer.

    Using xml to synthesize export of data to excel looks an excellent approach to achieve this as there won't be any intrinsic support of installed excel and hence the conformance could be a challenge.

    Hope this helps.

  • Hi,

    No. Excel functionality is to specific to be included in .NET Framework. If you are working with XLSX files, then you can manipulate them using System.IO.Compression and System.Xml namespaces because they are basically zipped collection of XML files. But be prepared to study hundred of pages of Open XML specification.

    I think it doesn't worth it. Just use Open XML SDK or some other 3rd party dependency.

    Here is one way to export to Excel in C#:

    // Create new Excel file.
    var excelFile = new ExcelFile();
    // Add new worksheet and export data from DataTable into it.
    excelFile.Worksheets.Add(dataTable.TableName).InsertDataTable(dataTable, 0, 0, true);
    // Export to XLS format.
    excelFile.SaveXls(dataTable.TableName + ".xls");

  • I've written a free C#/VB class, to export any DataSet/DataTable/List<> to an Excel .xlsx file using one line of code, using the free OpenXML libraries.

    Full details, with all of the source code and a demo are available here (no registration needed):

    Export to Excel library

    Here's what your code would look like:

    // Step 1: Create a DataSet, and put some sample data in it
    DataSet ds = CreateSampleData();
    // Step 2: Create the Excel .xlsx file
        string excelFilename = "C:\\Sample.xlsx";
        CreateExcelFile.CreateExcelDocument(ds, excelFilename);
    catch (Exception ex)
        MessageBox.Show("Couldn't create Excel file.\r\nException: " + ex.Message);

    And this year, I've improved it for ASP.Net devlopers, so you can export, without writing to an external file first, in one line of code:

    // In this example, I have a defined a List of my Employee objects.
    class Employee;
    List<Employee> listOfEmployees = new List<Employee>();
    // The following ASP.Net code gets run when I click on my "Export to Excel" button.
    protected void btnExportToExcel_Click(object sender, EventArgs e)
        // It doesn't get much easier than this...
        CreateExcelFile.CreateExcelDocument(listOfEmployees, "Employees.xlsx", Response);


    Everything you could need to get started, and you are free to modify the code yourself.

    Good luck !
