Data conversion from one format to another is known as data parsing. It is frequently used to organize data, usually to make the existing, frequently unstructured, unreadable data more understandable. A data parser can assist you in converting raw HTML data into a more understandable format, such as plain text. Programs have their own sets of rules for information parsing, and not all information is converted throughout the parsing process. In essence, a data parse program is used to add structure to unstructured data and transform it into file formats like JSON, CSV, and others.
