Those using POI 3.5 can also use
<em>org.apache.poi.xssf.extractor.XSSFExcelExtractor</em>, to perform
a similar task for .xlsx files.</p>
<p>In addition, there is a second text extractor for .xls files,
<em>org.apache.poi.hssf.extractor.EventBasedExcelExtractor</em>. This
is based on the streaming EventUserModel code, and will generally
deliver a lower memory footprint for extraction. However, it will
have problems correctly outputting more complex formulas, as it
works with records as they pass, and so doesn't have access to all
parts of complex and shared formulas.</p>
