Zanran helps you to find ‘semi-structured’ data on the web. This is the numerical data that people have presented as graphs and tables and charts. For example, the data could be a graph in a PDF report, or a table in an Excel spreadsheet, or a barchart shown as an image in an HTML page. Put more simply: Zanran is Google for data. At present, we extract tables and images from HTML, PDF and Excel files and will be processing PowerPoint and Word documents in the near future.
