TableReader in1  = CSVFactory.getFactory().getReader(f1);
TableWriter out1 = CSVFactory.getFactory().getWriter(f1);

// Returns implementation for classic Excel files
TableReader in2  = CSVFactory.getFactory().getReader(f2);
TableWriter out2 = CSVFactory.getFactory().getWriter(f2);

// Returns implementation for XML-based Excel files
TableReader in3  = CSVFactory.getFactory().getReader(f3);
TableWriter out3 = CSVFactory.getFactory().getWriter(f3);
