Make it so lines between cells don't disappear when you add fill. Having the lines gone makes it hard to read across the sheet horizontally.

quiero actualizar para el Mac excel 2011porque tengo archivos que si no no los puedo abrir.

While it is possible to create waffle charts manually in Excel, please add functionality to create waffle charts with one click. Waffle charts are arguably superior to pie charts for visualising proportions.

The default settings for the touchbar are a good start, but these Mac's have been out for years - where's the ability to customize the touchbar?

Problem: I am attempting to open a password-protected spreadsheet, but the dialog box asking for the password will not let me type the full password. Why does the password box have a character limit that doesn't match Excel 2010? I cannot open this spreadsheet now..
Solution: Please don't set up a password limit... the limit for file level passwords now is 15 characters. The PC Office 2007 & 2010 apps now support up to 256 characters, but on Mac this feature isn't taken over.

Since last Insider Version (190123), the "Wrap Text" cell formatting is giving totally wrong carriage return with multiline cell text (way too much spaces are taken)
See red zone in the printscreen attached.

In Excel for Windows you can export and import ribbons.

In Excel 2019 for macOS you can't.

Please add that function.

To be honest, I'm disappointed about the fact, that users of the mac version have such disadvantages.

I cannot see any reason, why that feature is not offered.

Just insert the button "From Web" as the same way in Excel for Windows

Need to fix a bug with mac Excel. After running a macro, the mouse cursor disappears. It reappears after typing in another program and coming back to Excel. This fix works sometimes but not all. This gets frustrating. The same macro runs fine in Windows Excel.

I'm told by your support staff that one cannot resize a chart that is itself a sheet, ie not an object in a sheet. So to resize a chart I have to copy/move it to be an object in another sheet. Big pain.

Another new glitch. Having created a formatted graph to my liking, I expect that copying the graph and changing only the cell addresses for the data (in Select Data) for a new graph, will not change the formatting. But no, the line and marker formats change. What a pain. Annoying but OK to re-format if only 1 graph but I am preparing a report with more than 30 graphs. What a time waste.

E.g., Find all blue text and Replace with white text and blue fill.

The idea is similar to what is described in the "Enable english formulas in Excel with any other predefined language" suggestion (http://bit.ly/2R268Gs)
Not only formulas in Excel, but the whole UI language should be an option, independently of the OS setting.
This would greatly help user support, education, helpdesk in multilingual environments

Allow Excel for Mac to connect to MS SSAS cubes.

After installing the latest (as of Jan-2019) update 16.20.0 (18120801), Excel crashes when opening ADRMS-protected documents. Attached are the crash dump and two videos. First video shows a successful opening of a protected document and starting of the update installation. Second video continues when the update installation is finished, and then shows opening of the same document and Excel crashing.

Multiple-cell, one-keystroke, change to absolute reference

I suggest you add a method of converting (say) a blocked 20 row x 30 column shaded portion of a work page from "standard" to absolute references. I have such a need, but I must make the change cell-by-cell, meaning 600 keystroke, not one. Each cell has a different. cell to which it refers.

ExportAsFixedFormat method produces a "Run-time error '1004':

Application-defined or object-defined error" when trying to save (export) a pdf to a user folder (/Users/user/Documents for example)

As I see it only works if one saves to the sandbox path of Office (Library/Group Containers/UBF8T346G9.Office), which is quite uncomfortable to work with.

Provide an option to have text (tool tips) below the icons on the Quick Access Toolbar. There could be icon+text or icon only.
