If you have used Excel for any length of time, you undoubtedly know that you can define names in your worksheets that refer to various cells and ranges of cells. You can even define names that refer to constants and to formulas. (The naming abilities of Excel are really quite handy.)
As you are developing macros, you may wonder if there is a way to retrieve a list of defined names within a worksheet. This is actually quite easy, if you remember that the defined names are maintained in the Names collection, which belongs to the Workbook object. With this in mind, you can use the following code to put together a variable array that consists of all the names in a workbook:

You might be interested in this freely available array function in My Excel Toolbox:
ListNames([Scope], [SkipHidden], [SkipHeader])
ListNames is most useful as a dynamic array in newer versions of Excel. You can also use it like this in older versions of Excel that do not support dynamic arrays:
SpillArray(ListNames([Scope], [SkipHidden], [SkipHeader]))
SpillArray will determine and populate the spill range for its array expression argument, simulating a dynamic array.

ReDim must be used at the procedure level (Sub, Function, or Property). Try a Collection instead. See https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/collection-object
or https://wellsr.com/vba/2018/excel/the-vba-collection-object/
For example:
Dim C As Collection ' Public at module level
Sub testGlobalA()
Set C = New Collection
For n = 0 To 9
C.Add (n * 3)
Next n
testGlobalB
End Sub
Sub testGlobalB()
For Each n In C
Debug.Print n
Next n
End Sub

Can I "redim" a Public array variable somehow ? I need to pull data into public arrays, but the length of the arrays will vary depending on when the code runs ... when declaring a Public array variable (e.g. Public arrFieldNames() as String), and then in a different sub I am re-dimming them, they seem to lose there "Public" status and go "out of context" once the sub ends ...
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
