Web data browser

Kirix Strata is a browser for gathering and manipulating data on the Web. You point Strata at a CSV file, an HTML table or an RSS feed on a Web site and it extracts the data, which you can then filter, join with other data, manipulate with formulas, export to other formats or upload to a database. A screencast demonstration says Strata "gives database structure to Web data." "… it was built to solve the problem of data usability," the company explains on its blog. "Basically, we're trying to give people the ability to handle structured data really easily, wherever they may encounter it." I gave Strata a try and did find it easy to use, and, at least for some operations, faster than manually grabbing data online and massaging it with scripting languages, spreadsheets and databases, as I normally do. There are Windows and Linux versions, with a Mac version promised for later. It's free only for now, while it's in beta, though they promise free licenses for the final version to users who give them feedback.
