<question>
Does HSSF support protected spreadsheets?
</question>
<answer>
<p>Protecting a spreadsheet encrypts it. We wont touch encryption because we're not legally educated
and don't understand the full implications of trying to implement this. If you wish to have a go
at this feel free to add it as a plugin module. We wont be hosting it here however.</p>

</question>
<answer>
<p>Excel stores dates as numbers therefore the only way to determine if a cell is
actually stored as a date is to look at the formatting. There is a helper method

<faq>
<question>
I tried to set cell values and Excel sheet name on my native language,
but I failed to do it. :(
</question>
<answer>
<p>By default HSSF uses cell values and sheet names as compressed unicode,
so to support localization you should use Unicode.
To do it you should set it manually:</p>
<source>
// for sheet name
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet s = wb.createSheet();
wb.setSheetName( 0, "SomeUnicodeName", HSSFWorkbook.ENCODING_UTF_16 );
// for cell value
HSSFRow r = s.createRow( 0 );
HSSFCell c = r.createCell( (short)0 );
c.setCellType( HSSFCell.CELL_TYPE_STRING );
c.setEncoding( HSSFCell.ENCODING_UTF_16 );
c.setCellValue( "\u0422\u0435\u0441\u0442\u043E\u0432\u0430\u044F" ); </source>
<p>
Make sure you make the call to setEncoding() before calling setCellValue(), otherwise what you pass in won't be interpreted properly.

<question>
Will POI read any spreadsheet and rewrite it with modifications.
</question>
<answer>
<p>POI is not guanteed to read the contents of any spreadsheet.
Certain features may cause spreadsheets to fail to read. More
problematic is rewriting spreadsheets. POI tried hard to
preserve the records of the original spreadsheet but some
features may cause problems. We advise that you limit the
formatting of spreadsheets you process so as to not be
unpleasantly suprised at a later stage.</p>
