What is XLS2CSVmra example in the Apache POI package? How to run XLS2CSVmra example?

XLS2CSVmra example in the Apache POI package is created by Nick Burch. It works as an XLS to CSV (Comma Separated Value) processor, that uses the MissingRecordAware EventModel code to ensure it outputs all columns and rows.

XLS2CSVmra example uses the HSSF (Horrible SpreadSheet Format) API, which supports Excel files in *.xls format only.

Here is the command to run XLS2CSVmra to convert workbook.xls generated by the BigExample into a CSV file:

C:\fyicenter>\local\jdk-1.8.0\bin\java
   -cp .;C:\local\poi-3.15\poi-examples-3.15.jar;
         C:\local\poi-3.15\poi-3.15.jar;
   org.apache.poi.hssf.eventusermodel.examples.XLS2CSVmra 
      workbook.xls > workbook.csv

If you open the output file, workbook.csv, in Notepad editor, you will see data from rolumns and rows from the *.xls file are extracted and displayed in CSV format:
