You can use EasyXLS Excel library. The below code get data from gridview and copy to an existing sheet:

// Load the existing Excel file
ExcelDocument workbook = new ExcelDocument();
workbook.easy_LoadXLSFile(pathToExistingExcel);

// Get the first sheet
ExcelWorksheet sheet = (ExcelWorksheet)workbook.easy_getSheetAt(0);

// Create a dataset that keeps the gridview datatable
DataSet dataSet = new DataSet();
dataSet.Tables.Add((DataTable)gridView.DataSource);

// Insert gridview data into sheet
sheet.easy_insertDataSet(dataset, false);

// Choose a name for the xls file 
string fileName = "Excel.xls";
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=" + fileName);
Response.ContentType = "application/vnd.ms-excel";

// Export new Excel file and prompt the "Open or Save Dialog Box"
workbook.easy_WriteXLSFile(Response.OutputStream);
