Windows/Mac/Linux: When you're gathering data for research or a project, it can be laborious entering each individual piece of information into a table. Import.io can grab data from a web page's code and create tables for you.
Once you've downloaded and installed the program, using Import.io is pretty simple. Open it up, and it works just like a browser. Type in the address of the web page you want to gather data from and then click the pink "io" button in the upper right-hand corner. From there, it asks you a few questions about the data you're trying to gather and gives you directions for each step. We used it to make a table of newly released Blu-Ray movies on Amazon and it worked really well.
Import.io is completely free for the time being and is available on Windows, Mac and Linux.
