Numbers wont open any excel .xls file generated in OpenOffice?
Always understood that I could, if necessary, open an excel file in numbers and then save as a native numbers file.
However, I have discovered that creating a spreadsheet in OpenOffice, saved in ".xls" format (have tried all of the options, 95, 97, 2000, etc) then try opening in Numbers will not work.
Numbers gives an error message that the file cannot be opened/may be corrupted/wrong format.
Does OpenOffice do something that breaks this ability?
Am running an iMac with latest updates
Thank you
