Question

I am trying to read datas from an uploaded xls. I have used this code part:

OleDbConnection connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(fileName) + ";Extended Properties=Excel 8.0");
                            if (connection.State == ConnectionState.Closed)
                                    connection.Open();
                            string query = "select * from [Sheet1$]";
                            OleDbDataAdapter da = new OleDbDataAdapter(query, connection);
                            DataSet ds = new DataSet();
                            da.Fill(ds);

But I get this error: External table is not in the expected format.

I am pretty sure I am giving the correct path. I was working and it is not. if it works then it wont fill the datatable. It gives an error that says that Sheet1$ object can not be found. Any help?

string savePath = "/Assets/UploadedFiles/";
                            string fileName = "Activity.xls";
                            savePath += fileName; 
OleDbConnection conn= new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Server.MapPath(savePath) + ";Extended Properties='Excel 12.0;HDR=YES'");
    if (conn.State == ConnectionState.Closed)
    conn.Open();
    string query = "select * from [Sheet1$]";
      OleDbDataAdapter da = new OleDbDataAdapter(query, conn);
                                DataSet ds = new DataSet();
                                da.Fill(ds, "Activities");
                                dt = ds.Tables[0];
                                conn.Close();
