I took a look at Jonathan Booth's most excellent XML File Data Service builder, and I like it. However, I find it easier to create sample data in a spreadsheet, so I made a few changes to his builder and present for your edification a CSV File Data Service builder.
If you examine my code and his, you'll see that it's 95% his stuff with only a slight change to read/write the file as a CSV (comma separated values) file instead of XML.
Edit May 1, 2014: fixed some bugs in the code.
