You must not restrict your conversion to just an Apple platform. There are too many convertors out there and since this is not a word document but a database you could restrict yourself if you want but in this case I think that's a bad idea.
https://www.google.com/search?hl=en&as_q=Microsoft+works+database+conversion finds the usual and some are free.
You might need a PC to mediate this one.
I had a G4 at one time that was running Microsoft works under OS9. The computer died but I still have the back up hard drive with the data.
Is there a way that I can convert MS Works database data so that it can be accessed on an iMac running OSX
I know about Dataviz, but this now seems to be defunct.
My main problem is an index of over two thousand 35mm slides that I do need.
Many thanks for any ideas.
