Converting SKCard Cardfiles to XP Address Book

Want to convert Sidekick 97 files
(especially the cardfile format *.SKCard)
to XP Address Book and Calendar formats.
Anyone know how to do this?
XP Address Book indicates it can import *.wab & *.csv files,
but it looks like Sidekick does not offer these options.
Sidekick offers:
Sidekick 97 Cardfile: (*.SKCard)
Sidekick 2 Cardfile: (*.SDB)
ASCII - Text Delimited (*.txt)
dBase III (*.DBF)
dBase IV/V (*.DBF)
Paradox 3.5 (*.DB)
Paradox 4.0/5.0 (*.DB)
and
Windows Cardfile (*.CRD)

thanks, mercury
