One example is the FDIC’s List of Failed Banks. Here is a simple trick to scrape such data from a website: Use Google Docs. The table on that page is even relatively nice because it includes some JavaScript to sort it. But a large table with close to 200 entries is still not exactly the best way to analyze that data. I first tried dabbledb for this task, and it worked in principle. After some digging around and even considering writing my own throw-away extraction script, I remembered having read something about Google Docs being able to import tables from websites. To extract a table, create a new spreadsheet and enter the following expression in the top left cell: =ImportHtml(URL, “table”, num). Once this is done, Google Docs retrieves the data and inserts it into the spreadsheet, including the headers. Discover a better way to ask questions online.
