Class TikaDocumentReader

java.lang.Object

org.springframework.ai.reader.tika.TikaDocumentReader

All Implemented Interfaces:

Supplier<List<Document>>, DocumentReader

public class TikaDocumentReader
extends Object
implements DocumentReader

A document reader that leverages Apache Tika to extract text from a variety of document formats, such as PDF, DOC/DOCX, PPT/PPTX, and HTML. For a comprehensive list of supported formats, refer to: https://tika.apache.org/3.0.0/formats.html. This reader directly provides the extracted text without any additional formatting. All extracted texts are encapsulated within a Document instance. If you require more specialized handling for PDFs, consider using the PagePdfDocumentReader or ParagraphPdfDocumentReader.
