<section><title>Version 1.5 limitations</title>
|
||
|
<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.

|
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/>
|
||
|

|
||
|
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/>
|
||

||
|
Pivot Tables<br/><br/>
|
||
|
Generating pivot tables is not supported. Reading spreadsheets containing pivot tables
|
||
|
has not been tested.
