Sorry if my question may yet again seem naive, but I should be grateful for advice. I have received two different xls files. According to "The Missing Manual" I should be able to drag them into Stuffit Expander and open them. All I get is - could not be converted to Appleworks file. Have I misunderstood? And is there anything I can do? I am on 10.3.3. Many thanks Keith Keith, If you own or purchase MacLinkPlus you will get icExel and icWord as part of their Special Bundle; these two translators will open Excel and Word and well as other PC file formats
