How to use JavaScript to export HTML table into Excel work sheet?

Sample Image - 6.jpg


I was playing with internet explorer context menu, suddenly I noted that I have menu item called "export to Microsoft Excel".


When I clicked on this command it is transferred the contents of the selected table to Microsoft excel.

How did I steal the code?

To guess what was happing on when I clicked on the context menu item, I used the IE feature, break at next statement (from menu item choose View-> Script Debugger->Break at Next Statement ), and made a small table and as I clicked on the menu and I got the VBScript file in Visual Studio .NET.

How did I link the datagrid with the script?

I have used something called HTC "HTML Components" which is a good thing to learn if you are developing an ASP.NET Server Control. My HTC script is divided in to two parts :

  • First one is how to display a small icon near the datagrid, and that was by
    1. creating HTML image object.
    2. putting the image near the datagrid table.
  • And the second part is how to plug it to the Microsoft Excel. In this task I did not do anything new but converting the VBS file to JavaScript one and add additional lines for checking the security settings.
           xlApp= new ActiveXObject("Excel.Application"); 
        alert("Please check the Internet security setting");
            return -1;

How to use it?

  • An important note before using the component is, to enable the "Initialize and script ActiveX controls not marked as safe"


    in the security tab in the internet security settings.

  • Copy the images and the HTC folders to your web project.
  • Add a the DLL file (DataGridProject.dll) to your references and to the Toolbox controls.
