This is killing me... I have these Numbers files but need to send them to someone who is using a pc with MS Excel. She won't be able to read the files if they are left as .numbers. The odd thing is that I have successfully saved some of the files as .xls and .xls.xls and even some as .xls.numbers. However, I have lost data when doing some of these savings - I have been taking the .numbers file and trying to save it as .xls but when I open the newly-saved file there's nothing there. Please look at the attached snapshot of my folder structure. Can you anything in there that might be causing my problem? The red arrows are just to highlight the ones I'm particularly interested in. tia.
