Data extraction is the fundamental process of gathering and retrieving data from various sources. This raw data can originate from a multitude of locations, including databases, websites, spreadsheets, documents, and even emails. The core purpose of data extraction is to collect this information and prepare it for further processing, analysis, or storage, often in a centralized location. Think of it as the first crucial step in transforming raw, often messy, information into a valuable asset that can fuel insights and decision-making.
