## Package org.apache.poi.xssf.binary Description

The org.apache.poi.xssf.binary package includes necessary underlying components for streaming/read-only processing of xlsb files.

POI does not yet support opening .xlsb files with XSSFWorkbook, but you can read files with XSSFBReader in org.apache.poi.xssf.eventusermodel.

This feature was added in poi-3.16-beta3 and should be considered experimental. Most classes have been marked @Internal and the API is subject to change.
