<p>The org.apache.poi.xssf.binary package includes necessary underlying components
for streaming/read-only processing of xlsb files.
</p>
<p>
POI does not yet support opening .xlsb files with XSSFWorkbook, but you can read files with XSSFBReader
in o.a.p.xssf.eventusermodel.
</p>
<p>
This feature was added in poi-3.15-beta3 and should be considered experimental. Most classes
have been marked @Internal and the API is subject to change.
