Class ExcelExtractor

java.lang.Object
  org.apache.tika.parser.microsoft.ExcelExtractor

public class ExcelExtractor
extends java.lang.Object

Excel parser implementation which uses POI's Event API to handle the contents of a Workbook.

The Event API uses a much smaller memory footprint than HSSFWorkbook when processing excel files but at the cost of more complexity.

With the Event API a listener is registered for specific record types and those records are created, fired off to the listener and then discarded as the stream is being processed.
