Any suggestion for a VBScript to test CSV files conversion?

I have several .TAB files which are of the CSV type.

I have an application that applies some modifications to some of these files (Modify value, Add field, remove field)

I need to do functional test for this application and I am considering writing some VBScripts to verify: - Fileds that are to be changed are correctly changed - Fields that are NOT to be changed remain intact

Any sugg开发者_JS百科estions on how to design the script?

Note: Some of the fields will be tables in the form """A1,B1,C1"",""A2,B2,C2"""

" ""A1,B1,C1"", ""A2,B2,C2"" "

Se these commas should not count to separate the CSV fields
