I'm giving you the code about export to excel i.e., now i'm
taking table from database and binding to excel sheet.That
Excel sheel is on my Local System.
Here i'm using Aspose(its a 3rd Party Tool)
Aspose reduces the code by setting data ,cells etc in Excel
Sheet.
Its a WebApplication.U can change it to Windows Application.

This code is for Setting the format for Excel Sheet:
public Workbook ExportToExcel(DataSet objDs, string
strHeader)
{
DataTable dtResult;
dtResult = objDs.Tables[0];

Workbook excel = new Workbook();
excel.Worksheets[0].Name = strHeader;

#region SettingHeaderInformation

excel.Worksheets[0].Cells
["B4"].Style.Font.IsBold = true;
excel.Worksheets[0].Cells["B4"].Style.Font.Size
= 12;
excel.Worksheets[0].Cells["B4"].PutValue
(strHeader);

excel.Worksheets[0].Cells
["D4"].Style.Font.IsItalic = true;
excel.Worksheets[0].Cells["D4"].PutValue
("Dated: " + DateTime.Now.ToLongDateString());

#endregion

//Exports data set into excel cells
Aspose.Cells.Cells exportCells =
excel.Worksheets[0].Cells;
exportCells.ImportDataTable(dtResult, false, 5,
0);

//This block is to header for exported data
table.
Aspose.Cells.Cells sheetCell = excel.Worksheets
[0].Cells;
for (int i = 0; i < dtResult.Columns.Count; i++)
{
if (i != (objDs.Tables[0].Columns.Count -
1))
excel.Worksheets[0].AutoFitColumn(i);

excel.Worksheets[0].Cells[5,
i].Style.Number = 49;
excel.Worksheets[0].Cells[5,
i].Style.Pattern = BackgroundType.Solid;
excel.Worksheets[0].Cells[5,
i].Style.ForegroundColor = excel.GetMatchingColor
(Color.FromName(SystemColors.InactiveCaption.Name));
excel.Worksheets[0].Cells[5,
i].Style.Font.IsBold = true;
excel.Worksheets[0].Cells[5,
i].Style.Font.Color = Color.White;
string headerTxt = dtResult.Columns
[i].ColumnName;
if (headerTxt.Contains(strDesc))
headerTxt = headerTxt.Remove
(headerTxt.IndexOf(strDesc));
else if (headerTxt.Contains(strDesc))
headerTxt = headerTxt.Remove
(headerTxt.IndexOf(strDesc));
excel.Worksheets[0].Cells[5, i].PutValue
(headerTxt);
if (i < objDs.Tables[0].Columns.Count)
excel.Worksheets[0].Cells[5,
i].Style.HorizontalAlignment = TextAlignmentType.Left;
else
excel.Worksheets[0].Cells[5,
i].Style.HorizontalAlignment = TextAlignmentType.Right;
}

return excel;
}


In Button we can write this code(its for binding the data
from database to Excel Sheet):

protected void Button2_Click(object sender, EventArgs e)
{
Aspose.Cells.Workbook workBook = new
Aspose.Cells.Workbook();
ExportMethods objExpMethods = new ExportMethods();
ds = objclass.getpagebal();//calling function from
businesslayer(table)
workBook = objExpMethods.ExportToExcel
(ds, "shanti_emp");//shanti_emp is a table name
workBook.Save("shantiExcel.xls",
FileFormatType.Default,
Aspose.Cells.SaveType.OpenInBrowser, Response);
}

U can convert it according to your convineince.
