<title>Overview</title>
|
|
|
|
<p>HSSF is the POI Project's pure Java implementation of the
|
|
Excel '97(-2007) file format. XSSF is the POI Project's pure
|
|
Java implementation of the Excel 2007 OOXML (.xlsx) file
|
|
format.</p>
|
|
<p>HSSF and XSSF provides ways to read spreadsheets create,
|
|
modify, read and write XLS spreadsheets. They provide:
|
|
</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>For people converting from pure HSSF usermodel, who wish
|
|
to use the joint SS Usermodel for HSSF and XSSF support, then
|
|
see the <link href="converting.html">ss usermodel converting
|
|
guide</link>.
|
|
</p>
|
|
<p>
|
|
An alternate way of generating a spreadsheet is via the <link href="http://cocoon.apache.org">Cocoon</link> serializer (yet you'll still be using HSSF indirectly).
|
|
With Cocoon you can serialize any XML datasource (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 either the org.apache.poi.hssf.eventusermodel
|
|
package, or the org.apache.poi.xssf.eventusermodel package, depending
|
|
on your file format.
|
|
</p>
|
|
<p>
|
|
If you're modifying spreadsheet data then use the usermodel api. You
|
|
can also generate spreadsheets this way.
