The Smartwrap project at Carnegie Mellon University is investigating how a crowd of internet users can collaboratively construct scrapers for webpages containing tables.
The project has constructed this tool to help people construct scrapers and extract spreadsheets from tables.
The tool is being actively developed, so we'd love to hear about what works and what does not. You can tell us about your experiences here
We've designed the tool to be easy to use, but it may help to watch some short videos first. You can see them here
