Web Scraper

This web scraper collects structured data by URL and extraction rules. Provide a target page URL and a set of selectors (CSS or XPath) to define data fields. The tool fetches the page, applies selectors, and returns records in JSON or CSV. It supports repeating across pages via a pagination rule and can pause between requests to respect site load.
Core logic validates inputs, applies selectors to pages, and normalizes field names for consistent output. It supports multiple selectors per field and nested structures. Outputs include an array of records and optional metadata such as total_records and success_rate.
The engine handles common issues such as missing fields by returning nulls and trims whitespace during normalization. It does not render dynamic JavaScript by default, but can be extended for advanced rendering if configured.
Use cases include product price tracking, article metadata collection, meta tag auditing, and competitor feature enumeration. The tool is designed for non-programmers while offering selector-based configuration for power users.
Overall, it provides reliable, repeatable data extraction with standard export formats to support data-driven decision making.
