Re: XLSX development from RPGLE

Blake,

I recall Scott mentioning that he was experimenting with building XLSX documents in RPG. I don't remember him supplying any details about this effort, but I do think I know what he's doing. Since XLSX document is implemented as XML, I'm sure that one could generate a native XLSX file with little real difficulty.

The file (.xlsx) is in fact an archive (zip, jar) that contains a few folders for content, and xml files for style, content, and so forth. I suspect that many of the items stored in the XLSX are common for all produced spreadsheets.

Hth,

Hello all...

I'm wondering if anyone has taken the opportunity to build an Excel 2010
(xlsx extension) file using POI, as explained by Scott Klement.

We've been doing work with building spreadsheets directly and when doing
conventional "xls" files we don't have any problems. But when trying to
do the "xlsx" versions, we keep getting "terraspace" issues...I'm guessing
some kind of method call with a null value but because the JVM drops out
of the calling program immediately, all I get is a core dump which is next
to impossible to analyze. We've done all the regular checks to verify
classpath values and having the latest POI objects, but still no joy. I'm
hoping someone else has tried this and run into similar problems so that I
can get some pointers on what to look for or adjustments to make.

Have a good day.
