+ <s1 title="Version 1.5 limitations">
+ <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/>
