Convert Pipe Delimited file into Comma Delimited

I have a utility to load data into an application.  It requires that the data be comma delimited.  One vendor supplying the data says they can only provide it in a pipe delimited file.  I need a simple script I can add to a batch file to change:

John|Doe|123 Main Street, Suite 200|New York|NY

into

"John","Doe","123 Main Street, Suite 200","New York","NY"

I need the data surrounded in quotes because of the poitential for imbedded commas in the addresses.

I'm not particular about the method used, but I am not a programmer.  I need something I can plug into a script so it will say:

convert filea.txt filea.cvs
utility filea.csv

Thanks.
