i have saved the libreoffice file in xlsx format and attached it thusly with no success ( ie some seem to be getting a blank file - don’t know why). I do have a license for office 2003 and it works, as long as I go thru Crossover. I found playonlinux a bit spotty for working. Of course I don’t know if these seniors are using ipads, samsung or regular laptops, so I am not aware of any patterns. I have tried using the internet version of office but it seems more trouble than just living with excel 2003. The only drawback to it is I have to pay a yearly fee to “codeweavers”.
