Thanks for the replies - here are some more specifics.  This is actually a dataset consisting of thousands of comma-separated rows.  SOME rows have fields with too many quotes.  Example:

2940924,Field1,Field2,Field3,"""Field 4 with commas possible in this field""",Field5,"""Another field with ""more quotes"""""

Not every row has this problem - some have just the one set in the appropriate columns.  I'm not even sure of the best way to tackle this, but was first looking for some sort of regex.  Thanks for any pointers.
