Fix Excel Online unsupported features forcing a save to new file
Support for opening Excel documents online now extends to ignoring included VBA, shapes, etc. so the workbook can be opened.
Unfortunately editing a workbook that includes any of these features forces the user to save another copy of the workbook that also dumps this content. Often a user only wishes to modify cell values or representation to update the workbook but this approach prevents even minor modifications and basic collaboration.
Perhaps a better model would be to provide an option to support the editing of workbooks that include these unsupported features after a warning that some elements are not supported.
