How to Automate CSV file manipulation?

I have a customer who uploads files to their system using CSV files which they are send from certain suppliers. The system rejects them if they are in the wrong format and they now have a new supplier sending their own style of CSV output. What I need to find out is how I can automatically parse the CSV file and copy the correct columns from their CSV into   the right columns on the new CSV. The new CSV file they recieve has all the data needed but just in the wrong places.

I think a macro of some sort would do this in Excel but I know very little about them?

Any ideas.. this must be a fairly simple thing to do (I Hope)

Thanks in advance

Depending on the specific changes you need, there might be better options using VBScript or Powershell ...

You'll need to be careful if data includes fields for: currency, dates, phone numbers

Its really just moving columns around and deleting ones which arent used? The tutorial you posted seems to be what I need.. just need to try it now.
@plug1

The usual approach to this is to 'map' the CSV columns into their destination columns/fields.

If this is going to happen for more than one source, then create a source (database, flat file, workbook, etc.) that you can easily edit and that a VBA routine can easily read.  You can do this specification with column names, if present, or with column numbers.  This way, you won't have to change your code.

Another useful tool is Powershell.  Do you know anything about Powershell?
