Don't repost: use the "Improve Question" widget to edit your question instead.

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalization if you want to be taken seriously.

I think you should determine a "range" in Excel and insert data to it, it faster than insert cell by cell.

C#

using Excel = Microsoft.Office.Interop.Excel;

SaveFileDialog sd = new SaveFileDialog();

sd.Filter = "Excel (*.xls)|*.xls";
sd.DefaultExt = "Excel files (*.xls)|(*.csv)";
sd.Title = "please select your NameA and Path";

if (sd.ShowDialog() == DialogResult.OK)
{

    Excel.Application xlApp;
    Excel.Workbook xlWorkBook;
    Excel.Worksheet xlWorkSheet;
    Excel.Range workSheet_range;
    object misValue = System.Reflection.Missing.Value;

    xlApp = new Excel.ApplicationClass();
    xlApp.Visible = true;
    xlApp.UserControl = true;
    System.Globalization.CultureInfo oldCI=                                    System.Threading.Thread.CurrentThread.CurrentCulture;
    System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-US");
    xlWorkBook = xlApp.Workbooks.Add(1);
    xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

    //Header
    xlWorkSheet.Cells[1, 1] = payGridView.Columns[0].HeaderText;
    xlWorkSheet.Cells[1, 2] = payGridView.Columns[1].HeaderText;
    xlWorkSheet.Cells[1, 3] = payGridView.Columns[3].HeaderText;
    xlWorkSheet.Cells[1, 4] = payGridView.Columns[4].HeaderText;

    workSheet_range = xlWorkSheet.get_Range(xlWorkSheet.Cells[1, 1],
    xlWorkSheet.Cells[1, 4]);
    workSheet_range.Font.Bold = true;


    for (int i = 0; i <= this.payGridView.Rows.Count - 1; i++)
    {
        xlWorkSheet.Cells[i + 2, 1] =  payGridView.Rows[i].Cells[0].Value.ToString();
        xlWorkSheet.Cells[i + 2, 2] = payGridView.Rows[i].Cells[1].Value.ToString();
        xlWorkSheet.Cells[i + 2, 3] = payGridView.Rows[i].Cells[3].Value.ToString();
        xlWorkSheet.Cells[i + 2, 4] =                       payGridView.Rows[i].Cells[4].Value.ToString();

    }

    xlWorkSheet.Rows.AutoFit();
    xlWorkSheet.Columns.AutoFit();

    xlWorkBook.SaveAs(sd.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue,    misValue, misValue, misValue, misValue);
    xlWorkBook.Close(true, misValue, misValue);
    xlApp.Quit();
    System.Threading.Thread.CurrentThread.CurrentCulture = oldCI;

    GlobalClass.releaseObject(xlWorkSheet);
    GlobalClass.releaseObject(xlWorkBook);
    GlobalClass.releaseObject(xlApp);

    MessageBox.Show("Your file is created successfully");
