Web Scraping
Website data extraction from page to usable dataset
Website data extraction turns page content into a predictable schema: one row per item, one field per attribute, or one record per page.
Define the schema first
Write down the fields you need before touching a tool. This avoids collecting everything simply because it is visible.
Handle lists and details separately
A listing page may provide names and URLs while detail pages hold richer attributes. Treat those as two stages when necessary.
Validate early
Check missing values, duplicates, data types, and whether the same field means the same thing across pages.
Choose the output
CSV is portable, spreadsheets are easy for teams, JSON fits application workflows, and databases fit larger recurring pipelines.

Responsible-use note: Access controls, source-site terms, privacy obligations, and applicable law can limit what you should collect. A tool being technically capable of extraction does not by itself establish permission.
