Ever needed custom formatted sample / test data, like, bad? Well, that's the idea of this script. It's a free, open source tool written in JavaScript, PHP and MySQL that lets you quickly generate large volumes of custom data in a variety of formats for use in testing software, populating databases, and... so on and so forth.
This site offers an online demo where you're welcome to tinker around to get a sense of what the script does, what features it offers and how it works. Then, once you've whet your appetite, there's a free, fully functional, GNU-licensed version available for download. Alternatively, if you want to avoid the hassle of setting it up on your own server, you can donate $20 or more to get an account on this site, letting you generate up to 5,000 records at a time (instead of the maximum 100), and let you save your data sets.
