The "Selector" section lets you change which page elements are scraped. You can specify the query as either a jQuery selector, or in XPath. You may also customize the columns of the table in the "Columns" section. These must be specified in XPath. You can specify names for columns if you would like.

After making any customizations, you must press the "Scrape" button to update the table of results.

A Chrome extension for writing custom web scraping programs and web automation programs.

A user can demonstrate how to scrape the first row of a dataset, and Helena will write a program for scraping the next hundreds or thousands of rows. Helena is also the name of the web automation language that the Helena extension uses. See for an overview of the Helena project.
