<a href="http://scraperwiki.com/" target="_blank">ScraperWiki</a> is a site and platform for building data scrapers that can transform unstructured data such as plain text files or tables on web pages (or even in PDFs) into structured data that can be queried with an API in JSON or XML format. Scrapers can be written in Python, Ruby, or PHP, and can be edited by anyone who has registered for the site (the "wiki" in the name). Non-programmers can request a data set and let the community help by putting together a working scraper. <strong>Source: </strong><a title="Journalism Accelerator" href="http://www.journalismaccelerator.com/about/what-is-the-journalism-accelerator/">Journalism Accelerator</a>
