<p>
The intent of this document is to outline some of the known
limitations of the
POI HSSF API's. It is not intended to be complete list of every bug
or missing
feature of HSSF, rather it's purpose is to provide a broad feel for
some of the
functionality that is missing or broken.
</p>
<ul>
<li>
Charts<br/><br/>
You can not currently create charts. This is planned for the
2.0 release. You can
however create a chart in Excel, modify the chart data values
using HSSF and write
a new spreadsheet out. This is possible because POI attempts to
keep existing records
intact as far as possible.<br/><br/>
</li>
<li>
Rich Text<br/><br/>
HSSF does not support rich text cells. Rich text cells are
cells that have multiple fonts and styles in the once cell. Any
attempt to read
a spreadsheet that has rich text cells will throw an exception.
This feature may
be supported in the future but it is not currently planned.
Patches are welcome.<br/><br/>
</li>
<li>
Outlines<br/><br/>
It is not yet possible to create outlines. Reading a
spreadsheet with outlines
may work correctly but has not been tested. Write support for
outlines may
be added in the future but it is not currently planned. Patches
are welcome.<br/><br/>
</li>
<li>
Macros<br/><br/>
Macros can not be created. The are currently no plans to
support macros. Reading
workbooks containing macros is supported but attempting to write
those workbooks
will fail. This is because macros are stored as extra file
sytems within the
compound document, and these are not currently kept when the
file is rewritten.<br/><br/>
