Is it the case that Application.MacroOptions is no longer supported in Excel for Mac (version 16.26, 2019)? As described by Microsoft (1) it should provide descriptions to to display a user-defined function (UDF) in a built-in or new category within the Insert Function dialog box, a description and status bar text.
This seems to be be an old chestnut, as discussed in various online postings, e.g. most usefully in (2) and (3) below.
I have tried doing this until blue in the face, using the simplest imaginable UDF that adds two numbers together. Application.MacroOptions doesn’t seem to work at all under any circumstances in Excel for Mac. I have tried running the code when Excel starts by calling a sub from the Auto_Open() in my PersonalMacroWorkbook. The code fails, error 2004. I’ve tried running it by calling the same code after excel opens, either in the PersonalMacroWorkbook, or in a .xlsm workbook other than the one containing the VBA code for the UDF to be described; in both cases, again the code fails with the same error.
Finally, I’ve tried running the Application.MacroOptions code in the workbook containing the UDF to be described, being sure to do so before first use of my UDF. Here, the code runs with no error - I can step though it to confirm that, BUT, it has absolutely no effect. If the Formula Builder is already open when I type the name of the UDF in a cell, I do see the name of my UDF and its result in the Formula Builder. But that happens anyway, regardless of whether or not code containing Application.MacroOptions for the UDF has been run. And absolutely nothing specified in Application.MacroOptions appears in the Formula Builder or elsewhere; my UDF doesn’t appear under any category regardless what numerical or string value is given for the Category argument, and nothing appears in the status bar or in the Formula Builder under Fx or Syntax where info is shown for the built-in Excel functions.
So should I conclude that Application.MacroOptions is no longer supported in Excel for Mac? Or have I missed something and more undocumented steps are required to make it work? It would be mighty helpful for Microsoft to clarify this so that Excel for Mac users need not to waste hours trying to get this to work!
