Put the all Excel files in one folder in your application
Add one link on your page like

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/Images/02639_SandeepSureshAkhare_BFSI_Self Appraisal.xls" Target=_self>HyperLink</asp:HyperLink></td>

and open it i think this one of the simplest way to open any file
The other is COM object which makes your application bulky

Thanks and Regards

Please Import Microsoft Excel from the COM Tab of the Add Reference Page.

See if this code helps U.
Try to understand this and write Ur code accordingly.

Create a table in the webpage.
Add the rows and its contents dynamically by iterating through the corresponding object.

Excel.Workbook objWorkBook = ExcelObj.Workbooks.Open("d:\\one.xls", 0, true, 5,
"", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true);

Excel.Sheets sheets = objWorkBook.Worksheets;

Excel.Worksheet objworksheet = (Excel.Worksheet)sheets.get_Item(1);

Excel.Range objRange = objworksheet.get_Range("A" + i, "J" + i);
System.Array objvalues = (System.Array)objRange.Cells.Value;
string[] strArray = ConvertToStringArray(objvalues);

//Code to add data to the existing cells

Mr Arun I am extremily sorry to tell u that this code didnt help me.Now i have the code to convert excell file into html file as follows

using Excel = Microsoft.Office.Interop.Excel;

Microsoft.Office.Interop.Excel.Application excel = null;
Microsoft.Office.Interop.Excel.Workbook xls = null;
excel = new Microsoft.Office.Interop.Excel.Application();
object missing = Type.Missing;
object trueObject = true;
excel.Visible = false;
excel.DisplayAlerts = false;

xls = excel.Workbooks.Open(strFilePath, missing, trueObject, missing,

missing, missing, missing, missing, missing, missing, missing, missing,

missing, missing, missing);

object format = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;

IEnumerator wsEnumerator =
excel.ActiveWorkbook.Worksheets.GetEnumerator();
int i = 1;
while (wsEnumerator.MoveNext())
{
Microsoft.Office.Interop.Excel.Worksheet wsCurrent = Convert.ToString(Microsoft.Office.Interop.Excel.Worksheet.ReferenceEquals);
String outputFile = strFilePath + "." + i.ToString() + ".html";
wsCurrent.SaveAs(outputFile, format, missing, missing, missing,
missing, missing, missing, missing, missing);

}
excel.Quit();

I have added the microsoft excel library through add reference. but it is showing error as follows

The type or namespace name 'IEnumerator' could not be found (are you missing a using directive or an assembly reference?)
