It's called DelimitedFileViewer (Was unable to come up with a funkier name;) ). I had created the first working version of this way back in November 2007. After a lot of cosmetic improvements, it works well and looks good. There are a lots of features like Finding stuff and Sorting stuff on one of the fields. It also has a nice drag and drop feature which lets you drag and drop files onto the application. Click on the following link to download this utility
