Tool to automatically grab data from sites
Automatically grab sets of data from websites and download it as a CSV or JSON file. Basically, a small extension that acts as a screen scraper and lets your easily scrape data from a website. Let's say you have a website with: <div class="foo"> <span class="name">Joe</span> <span class="city">Seattle</span> <img src="profilepic.png"></img> </div> <div class="foo"> <span class="name">Jean</span> <span class="city">Austin</span> <img src="profilepic_i.png"></img> </div> <div class="foo"> <span class="name">Ben</span> <span class="city">Boston</span> <img src="profilepic_asbfdsi.png"></img> </div> Grab all that data by selecting ".foo" and then make columns for ".name", ".city", and the "src" attribute of "img". Enjoy your screen scraping!
