Excel to text files conversion

Hi I have created one script which is taking Excel file and converting it to .txt files.But the code is not converting some of the excel files correctly. I dont know the reason, the reason might be different formats in one worksheet or some other issue. But the thing is if the format is coming differenty then also I want to handle the excel and each column should be generated in .txt files.Can anyone please help me regarding this problem as this is very urgent.

The execution engine calls this method when the task executes.
To access the object model, use the Dts property. Connections, variables, events,
and logging features are available as members of the Dts property as shown in the following examples.
To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
To post a log entry, call Dts.Log("This is my log text", 999, null);
To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);
To use the connections collection use something like the following:
ConnectionManager cm = Dts.Connections.Add("OLEDB");
cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";
Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
