<p>HSSF is the POI Project's pure Java implementation of the Excel '97(-2002) file format.</p>
|
||
|
|
<p>HSSF provides a way to read spreadsheets create, modify, read and write XLS spreadsheets
|
||
|
|
It provides:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>low level structures for those with special needs</li>
|
||
|
|
<li>an eventmodel api for efficient read-only access</li>
|
||
|
|
<li>a full usermodel api for creating, reading and modifying XLS files</li>
|
||
|
|
</ul>
|
||
|
|
<p>
|

Truth be told there is probably a better way to generate your spreadsheet
|
||
|
|
generation (yet you'll still be using HSSF indirectly). At the time of
|
||
|
|
this writing we're in the process of moving the HSSF Serializer over to
|
||
|
|
the <link href="http://xml.apache.org/cocoon">Apache Cocoon
|
||
|
|
Project</link>. With Cocoon you can serialize any XML datasource (of
|
||
|
|
which might be a ESQL page outputting in SQL for instance) by simply
|
||
|
|
applying the stylesheet and designating the serializer.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
If you're merely reading spreadsheet data, then use the eventmodel api
|
||
|
|
in the org.apache.poi.hssf.eventmodel package.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
If you're modifying spreadsheet data then use the usermodel api. You
|
||
|
|
can also generate spreadsheets this way, but using Cocoon (which will do
|
||
|
|
it this way indirectly) is the best way...we promise.
