You can use OLEDB to create and manipulate Excel files. Check this: Reading and Writing Excel using OLEDB.

Example:

using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\temp\\test.xls;Extended Properties='Excel 8.0;HDR=Yes'"))
{
  conn.Open();
  OleDbCommand cmd = new OleDbCommand("CREATE TABLE [Sheet1] ([Column1] string, [Column2] string)", conn);
  cmd.ExecuteNonQuery();
}
