That was my first hope, but there doesn't seem to be a quote option  
in Excel 2000, hard as that is to believe... Unfortunately, they are  
a remote client, so I can't look at the 'Save As' options myself, but  
I spent a long time on the phone with them, trying to get them to  
look for such an 'advanced' option. No luck. It's either not there,  
or they are blind.

That would be easy, but they upload this file frequently, and I need  
an automated solution.

Me too. Weird.

I've got a prototype working, but now I've discovered that even the  
tab delimited file is malformed... the Ruby CSV Library chokes on one  
of the data lines. Illegal use of quotes. Bummer...
