Data extraction is the process of retrieving information from various sources, such as databases, documents, or websites. This information can be structured, like data in a spreadsheet, or unstructured, like text in a PDF. The goal is to convert this data into a usable format for analysis or storage. Once extracted, the data can be processed and analyzed to gain insights or support decision-making. Tools and techniques, such as web scraping or ETL (Extract, Transform, Load) processes, are often used to automate data extraction. This helps organizations efficiently gather and utilize valuable information from diverse sources.
