Generate Data dot com is a very cool little online app (or free open source downloadable program) which lets you create dummy data for whatever you want. It can deliver HTML, Excel, CSV, SQL and XML formatted data in international formats, for download and import.
It gives you a nice set of data choices to use, from name, email, dummy address to random words/phrases and incremental numbers, which should cover just about every generic need. If you do web development or design, this is a great tool for populating your creations in the early stages.
Offering a donation of $20.00 gets you an online account for a year where you can store data for repeat use. Most Excellent Bargain!
