Apache Tika is an open source library that is used for document type detection and content extraction from various file formats. It uses various existing document parsers and document type detection techniques to detect and extract data. Using Tika, we can develop a universal type detector and content extractor to extract both structured text as well as metadata from different types of documents such as spreadsheets, text documents, images, PDFs, and even multimedia input formats. Apache Tika provides a single API for parsing different file formats. The existing parser libraries are encapsulated under a single interface, called the parser interface.
