To supplement marto's great links, you may also have on your machine something called "OLE Browser" or "Type Library Browser" if you installed Win32-OLE-0.1403 or upgraded from that to a later version. You might find it in C:\Perl\html\OLE-Browser or C:\Perl\html\lib\site\Win32\OLE depending on your install.

Something else I've found to be very handy indeed is West Wind Technology's GetConstants utility, which allows you to look at all those cryptic constants MS Office uses. (A short snippet of output is below.) Note that they do shuffle the links around occasionally, so it may be necessary to do some searching. :-)

*** Constant Group: WdTableFieldSeparator
#define wdSeparateByParagraphs                            0
#define wdSeparateByTabs                                  1
#define wdSeparateByCommas                                2
#define wdSeparateByDefaultListSeparator                  3
