Jira excel attachments doesn't upload properly

[Clariza Bergeron]

Hi,

I am wondering how should I prepare my excel file when I attached it. 
currently some of my attachments when I open , it does not load the whole page , the right side of the file is always cut out. 

Thanks, 

Clariza

Honestly, I think that your file is not broken or corrupt or anything. It is very likely to be perfectly healthy, but the Excel preview dialog cannot display its whole content.

If you download it and open it with Excel, is the problem gone?
