For column content section in your code add

C#

if (i == 0)
                        {
                            xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1.Columns[j].HeaderText.ToString();
                        }

Your Updated COde Will Be..

C++

//for Column content

for (i = 0; i <= dataGridView1.RowCount -1; i++)

{
                
for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)  
{
  if (i == 0)
{
xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1.Columns[j].HeaderText.ToString();//if the i is zero then read the column header text of datagrid and send to excel work sheet..
}
else{//else send the data from datagrid cell to excel

DataGridViewCell cell = dataGridView1[j,i];
xlWorkSheet.Cells[i + 1, j + 1] = cell.Value;
}           
}
