As a result, data extraction is usually done by a data extractor, which is a software application that retrieves and extracts data from a web page (or a series of pages) and presents it in a formatted structure. Most likely, this is a spreadsheet or a machine-readable data interchange format like JSON or XML. This data can subsequently be utilized for a variety of reasons, including displaying it to people via a user interface or processing it by another software.
