PageSieve por Julius K

PageSieve is a browser extension that assists with the extraction of
structured data from any webpage you visit. Define field names, CSS
selectors and (optionally) pagination strategy through a sidebar and extract
and export data in a variety of formats.

The extension is designed around a few core principles:

• Ergonomic CSS definition - discovering CSS selectors should be a simple point-and-click operation.
• Minimal UI - in-browser sidebar that does not take you to a different application.
• Local first - scraping can be done entirely on device.
• Reusable recipes - once you define fields and selectors, you can save your
  configuration for use at a later date or share it online.

Some key features include:

• Sidebar UI for defining:
  • Field name
  • CSS/XPath selector
  • How to move to next page
• Tabular display of extracted values
• Export extracted data in a variety of formats
• Import / export configurations as JSON files
• Works on any website your browser can load
