schasins/helena
A Chrome extension for writing custom web scraping programs and web automation programs. Just demonstrate how to collect the first row of data, then let the extension write the program for collecting all rows.
Helena is a Chrome extension that helps researchers, social scientists, and data scientists automate collecting information from websites. You show it how to get the first piece of data, and it generates a program to collect hundreds or thousands of similar data points. This is ideal for anyone who needs to gather large datasets from well-structured web pages without writing code.
262 stars.
Use this if you need to extract structured data from many web pages and prefer to demonstrate the process rather than code it.
Not ideal if you need a professional-grade, production-ready tool for mission-critical web scraping, as Helena is a research prototype.
