My Excel file seems to be damaged. Do you have a backup of the file a few days ago?

Hey aviran5439, welcome to our Community!

You can use these steps, in order to check the file's version history. Let me know what you find there. 

Also, when you say that the file is damaged, can you share some more info with me? Which platform do you use when you try to preview it, and do you get any specific errors? 

Keep me posted, and we'll take it from there! 

The file open but is empty, without  My drawings

Do you have a copy of the file few days ago in your servers? 

The file Name is מחשבון 

I see, thanks for letting me know aviran5439. 

We don't have the visibility, and tools here on the Community to check for the file's history. 

Did you try the steps I provided earlier, in order to check on your end? If you had any trouble checking the file's version, let me know and I'll be more than happy to assist. 

The link already given tells you how to view and access all the versions Dropbox stores. If it isn't in the Previous Version history Dropbox doesn't have another copy.
