Apache POI is a Java library for reading and writing Microsoft Office documents in both OLE2 binary formats (XLS, DOC, PPT) and Office Open XML formats (XLSX, DOCX, PPTX). It provides high-level usermodel APIs per application plus low-level components for the OLE2 filesystem, document properties, and OOXML packaging.
Use cases
- read and write Excel spreadsheets from Java
- generate Word docx documents programmatically
- create PowerPoint presentations in Java
- extract text from Office documents for indexing
- parse Outlook msg and winmail.dat files
- convert legacy xls files to xlsx
- read Visio diagrams in Java
When to choose
- you need full programmatic manipulation of Excel, Word, or PowerPoint files on the JVM
- you must support both legacy binary (OLE2) and modern OOXML formats
- you need text extraction from Office documents for search or processing pipelines
When to avoid
- you only need to read simple CSV or plain-text data files
- you are not on the JVM and need a native or Python solution
- you need pixel-perfect rendering of Office documents rather than data access
