How can I convert an old Numbers file to be compatible with the new Numbers version, without having access to the old?
I received a Numbers file created in iWorks version 8 or earlier, but only have the newest version of Numbers on my MacBook Air. I can't request the sender to reformat the file. Is there any way to convert the file so I can open it in the new Numbers version?
