Hi, I hope I am asking this question in the right category. If not I am sorry. But my problem is that I have generated an Excel file on my desktop and copied and pasted into my Dropbox. When I open this file in Dropbox on my iPhone I can view, cut and copy the file but I cannot edit it. I have the Excel app installed on my phone, but even using the app the function to edit is not there. Does anybody out there know a solution to this as I am led to believe I should be able to edit this kind of file
