Issue with Excel - "Excel file format is not valid"
Excel file format is not valid. Please help as unable to open Excel.
I think I found the solution.
If you disable the office dropbox add-in the problem doesn't seem to occur anymore. You can still save to dropbox via file explorer making it redundant anyhow.
to do this, open excel, go under file, Choose "Options", and navigate to "add-ins".
From there locate the Dropbox Add-in and right click, select "disable".
Should stop it from being an issue.

Dropbox StaffHey flew,
Hmmm... Mere guess here, since I've encountered the same error in the past.
If it's an .xls file, you'll probably need to modify (:repair) the file extension to .xslx. If you run a google-search, you'll easily find some articles that will walk you through the process as well.
If this persists, would you mind including a screenshot
After checking throughally it seems when this is done in Excel 2016, it saves as a CSV format but with a .xlsx file extension. Making Excel think it's corrupted when it's just under the wrong file extension. Seems to be an issue exclusively with using the dropbox saving function in office.
Can someone else test this out? I am unsure why this is happening this way. The workaround is simple, save locally instead of with dropbox. But feels like a bug someone should be made aware of.

I'm seeing the opposite. When I do a Save As, specify Dropbox as the location and select CSV as the file type, it's saving the file in the XLSX format with a .csv file extension. Saving to the Dropbox folder directly, without using the Save to Dropbox functionality, the file is saved correctly.
So it seems it's a problem with the save as function in general in excel not just any particular file format. The function of doing a save as to a different format is not working correctly when saving to dropbox.
Wish we could get some support members to look at this and give us an idea on why this is happening and what fix there is if any.

Merging several posts with the same description.
- Found same issue today this helped Thanks.
Definately an issue with the save to dropbox add-in. Saving a csv to xlsx , using windows explorer to browse to the dropbox folder path has no issues.Hi there
I am all of a sudden having the same problem, using Excel 2016 pro. I have removed the dropbox add in adn tried saving in different formats. This is a real problem for a company that uses spreadsheet after spreadsheet, any updated fixes welcome. Thanks
