Which PL/SQL function converts documents such as PDF, DOC, JSON, XML, or HTML to plain text?

The function that converts various document formats like PDF, DOC, JSON, XML, or HTML to plain text is designed to facilitate the extraction of readable content from complex file formats. In this context, the DBMS VECTOR_CHAIN.UTL_TO_TEXT function is particularly relevant as it is specifically built for this purpose within the Oracle database environment.

This function reliably processes different types of documents, extracts the text, and provides it in a plain text format, which is essential for further data analysis and searching. The name suggests a utility function that leverages chains of underlying processes to convert these diverse formats, catering to the versatile needs of developments in text mining, natural language processing, and search optimizations using vector technologies.

While there are other functions that might perform related tasks, they do not specifically cater to the conversion of various document types to plain text as effectively. Therefore, selecting DBMS VECTOR_CHAIN.UTL_TO_TEXT highlights an understanding of using the appropriate tools designed for working with textual data derived from a wide array of formats.
