Unless you have a strong reason for using OleDb for this, I recommend against it. The usage is very limited and archaic and the providers are no longer shipped with Office 2013 or in Windows. NuGet EPPlus and make your life a lot easier.

However, here is an example of how to do an insert and update using OleDb:

        using (OleDbConnection cn = new OleDbConnection(connectionString))
        {
            cn.Open();
            using (OleDbCommand cmd1 = new OleDbCommand("INSERT INTO [MySheet$] (COLUMN1, COLUMN2) VALUES ('Count', 1);", cn))
            {
                cmd1.ExecuteNonQuery();
            }

            using (OleDbCommand cmd1 = new OleDbCommand("UPDATE [MySheet$] SET COLUMN2 = 5 WHERE ID = 1", cn))
            {
                cmd1.ExecuteNonQuery();
            }
        }
