Answer 1

I did not intend to steal @Jake and @Cornelius's answer, so i tried editing it. but it was rejected. Anyways, the only improvement I have to point out is about avoiding extra blank column in excel after paste. Adding one line dataGridView1.RowHeadersVisible = false; hides so called "Row Header" which appears on the left most part of DataGridView, and so it is not selected and copied to clipboard when you do dataGridView1.SelectAll();

private void copyAlltoClipboard()
    {
        //to remove the first blank column from datagridview
        dataGridView1.RowHeadersVisible = false;
        dataGridView1.SelectAll();
        DataObject dataObj = dataGridView1.GetClipboardContent();
        if (dataObj != null)
            Clipboard.SetDataObject(dataObj);
    }
    private void button3_Click_1(object sender, EventArgs e)
    {
        copyAlltoClipboard();
        Microsoft.Office.Interop.Excel.Application xlexcel;
        Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        xlexcel = new Excel.Application();
        xlexcel.Visible = true;
        xlWorkBook = xlexcel.Workbooks.Add(misValue);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);          
    }
