 <b>Apache POI</b> (Java-based and platform-independent too) is based on the OpenOffice.org I/O Excel r/w routines. It is a more versatile than JExcelAPI, while it doesn't support BIFF5 it does support BIFF8 (Excel 97 – 2003) and OOXML (Excel 2007).</DT>
 <DT>It is slower than native JXL let alone Excel &amp; COM but it features active formula evaluation, although at the moment (end of 2013, v. 3.9) still not *all* Excel functions have been implemented (a daunting task for the POI devs, as it is hard to keep up with MS here). I've made the relevant subfunction (xls2jpoi2oct) fall back to cached formula results (and yield a suitable warning) for non-implemented Excel functions while reading Excel files. <BR>

+<b>OpenXLS</b> (an open source version of Extentech's commercial Java-xls product) is still a bit experimental. It seems to work faster than JExcelAPI, but it has other issues - i.e., processing of OOXML files is still unreliable. In addition OpenXLS scatters Extentech.tmp files here and there. For .xls (BIFF8) it works OK.<BR>
 <BR>
 <b>UNO</b> (invoking OpenOffice.org (OOo) or LibreOffice (LO) or clones behind the scenes, a la ActiveX) is experimental. It works FAST (i.e., once OOo itself is loaded and initialized which can take some time) and can process much larger spreadsheets than the other Java-based interfaces because the data are not entered in the JVM but in OOo's memory.<BR>
 A big stumbling block is that odsclose() on a UNO xls struct will kill ALL OpenOffice.org invocations, also those that were not related to Octave! This is due to UNO-Java limitations.<BR>
 The underlying issue is that when Octave starts an OpenOffice.org invocation, OpenOffice.org must be closed for Octave to be able to exit; otherwise Octave will wait for OOo to shut down before it can terminate itself. So Octave must kill OOo to be able to terminate.<br>
 A way out hasn't been found yet.<br><br>
 All in all, of the three Java options I'd prefer Apache POI rather than OpenXLS or JexcelAPI. But the latter is indispensable for BIFF5 formats. Once UNO is stable it is to be preferred as it can read ALL file formats supported by OOo (viz. wk1, ods, xlsx, sxc, ...). If you need to process really large spreadsheets, UNO is by far the fastest option (behind COM on Windows systems), but for smaller spreadsheets you'll find that the other interfaces are more efficient.<DT><br>
