I share an Excel file (created on a Mac) with someone who opens it and edits using Google Docs. when I go to open the file after he has made changes, the mini preview displays the latest changes, but when I proceed to open it in Excel, on an iOS device, some, but not all of the changes he has made display. Possibly he has saved at a certain point but not later, but I don’t know.
Can he update the file successfully using a PC (which I forgot to mention) using Google Docs, or is it necessary that he use Excel? What could cause only changes up to a certain version to sync, but not later ones?
I only know about this file because this is the only Excel file I am sharing through DropBox. It is in a shared folder. I was able to restore it from a backup, and now have the restored one as well as the damaged one in the DropBox folder. It reflects the missing entries. However, I moved it to a different folder and then moved it back. I don't know whether, had I gone directly to DropBox, whether it would have been damaged before being moved and put back.
I'd be happy to give you the link, provided it is confidential. I don't know exactly what process the other user is using, and he is not sufficiently technical to give me a precise, step-by-step description. I am guessing it's a Google Docs issue, because that program has to translate the Excel file to open it and then, I assume, try to save it as an Excel file again.
Maybe I just need to require that he install Excel on his PC >>>
