CSV2XML allows you to convert a CSV file format to an XML file format without effort. The only thing you need is to have a CSV file with the first row containing the names of the fields. You can then choose between a comma, semicolon, tab or vertical bar delimiter before specifying the row's name and launch the convertion.
When you launch the convertion, a progress-bar let you know the progress of the job.
This little piece of software is lightweight, but powerful and useful. You always need that kind of stuff close at hand.
