[GNC] Convert CSV to QFX?

[Carl W.]

   Is there a simple and easy way to convert a CSV file to QFX?  Maybe OFX
   is equivalent to QFX?
   Background;
   Our credit card company no longer provides QFX files for download.
   They only provide CSV file format.
   Perhaps you have a better suggestion on how to easily get CSV data into
   GC?
   I've seen on-line converters of which, due to the nature of banking
   information and privacy, I'm extremely suspicious.
   Thank you,
   Carl W.
