Excel Filter and Sort UDFs – Amazing!



In late September 2018, Microsoft revealed a number of fascinating new Excel worksheet functions.

Bill Jelen has churned out an amazing 66-page ebook on the new functions.

I strongly recommend that you look at the links listed above. Only then will you be able to appreciate what is presented in this article.

But, I don’t have immediate access to looking at these functions in the newest versions of Excel. So, that started me thinking: Could something similar to this work in a user-defined function (UDF)? My latest UDF creation, along with links to other interesting uses of UDFs can be viewed here.

Well, to make a long story short, it can and furthermore they operate on the ORIGINAL DATA. This means they can filter a dataset in place and sort data in place instead of creating a duplicate dataset or subset like to new Excel functions do. You may ask how a UDF, entered in a worksheet cell remote for the data, can filter and/sort that table of data, and even I did not think that it was possible, or I would have exploited this long ago.

So, the FILTERFUN function presented here (I would have called it FILTER but I would not want it to conflict with the new Excel functions if used alongside them) can filter a table of data. In the figure shown below, the FILTERFUN function is shown along with a set of data. This UDF has 2 arguments, the field in the table to be filtered and the criteria to be used for the filter.


If you are familiar with using Excel’s advanced data filter, you will note that the criterial in the 2nd argument uses the same syntax and has wildcard filtering abilities. The result for entering this formula can be seen in the next figure.


The code for the FILTERFUN function fixes the location for the table to start in cell A1, but that can easily be modified, as can be seen in the code for the next magical UDF, the SORTFUN function.

This UDF has 3 arguments: the table range, the field to be used as the sort key, and the desired sort order, as shown:


In this case, when the SORTFUN function is entered, the desired sort of the table is performed.


The following code for both of these functions is shown below.


These functions provide a utility that can be made to mostly emulate the new Excel FILTER and SORT functions, while also allowing the desired result without creating new data tables.


I hope you find this technique useful. If so, share it with your Excel friends and colleagues.

#Excel: Generate a List of Antonyms Using an User-Defined Function (UDF)

It really is amazing what you can do with an Excel user-defined function (UDF). Here is a list (not comprehensive) of articles from my website that demonstrate clever and unusual uses of UDFs.

In this article, I will show how to use an Excel UDF to return a delimited string of antonyms. It uses Word VBA, so in order for the code to work, you must add a reference to the Microsoft Word Object library in the VBE, as shown below.


Then, the following code for the UDF can be placed in a general module in the VBE.

Function AllAntonyms(TheWord As String)

Dim Alist

Alist = SynonymInfo(Word:=TheWord, LanguageID:=wdEnglishUS).AntonymList

For i = 1 To UBound(Alist)

If i = UBound(Alist) Then

DList = DList & Alist(i)


DList = DList & Alist(i) & “,”

End If


AllAntonyms = DList

End Function

The result for using this UDF in a worksheet cell with the word “excited” as the lookup for antonyms in shown in the following figure.


There are a number of possibilties for extending/modifying this example to other useful UDFs. I hope that you find this useful in that regard.

xlCubeSuper An Excel Game Explained – Part6

This article is Part6 of a detailed explanation of the parts that went into the making of my xlCube game.

Sub NewGame()

Over = False







End Sub

The routine AskForGameLevel was needed in the older version of this game, but adding 2 more cubes changed my mind about having this option, so it is now set to 7 in this version.

The routine tdAddNamedRanges was discussed in a previous post in this series.


Sub IniVar()

hint1Val = 0

hint2Val = 0

hint3Val = 0

hint4Val = 0

hint5Val = 0

hint6Val = 0

hint7Val = 0

End Sub

This procedure simply sets variables used in the hint portion of the menu.

Sub ClearBoard() ‘prepares the worksheets for another game (some code can be cleaned up here)


Application.ScreenUpdating = False


For Each wsh In Sheets




Sheets(Array(“1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “10”, “11”, “12”, “13”, “14”, “15”, _

“16”, “17”, “18”, “19”, “20”)).Select




With Range(“board”)


.Font.ColorIndex = 1

ActiveWindow.SelectedSheets.FillAcrossSheets Range:=Range(“board”), Type:=xlAll

End With

This changes the font color for all cells in the board back to black.





For Each wsh In Sheets

If wsh.Name <> “Scores” Then


End If



Application.ScreenUpdating = True


End Sub


Sub DeleteOldCubes()

On Error Resume Next

With ThisWorkbook

For d = 1 To 7

.Names(“cShip” & d).Delete

.Names(“centerShip” & d).Delete


End With

End Sub

Since the center of each cube is a named range, they can easily be deleted by using the Names property.


Sub MakeCubeMenu() ‘creates menu for xlCube

Dim xlCubeMenu As CommandBarPopup

DeleteCubeMenu ‘ deletes menu if it exists

Set xlCubeMenu = CommandBars(1).Controls.Add(Type:=msoControlPopup, temporary:=True)

xlCubeMenu.Caption = “&xlCube”

Set nGameMenuItem = xlCubeMenu.Controls.Add(Type:=msoControlButton)

With nGameMenuItem

.Caption = “&New Game”

.OnAction = “NewGame”

End With

For h = 1 To 7

Set nHintMenuItem = xlCubeMenu.Controls.Add(Type:=msoControlButton)

With nHintMenuItem

If h = 1 Then

.BeginGroup = True

End If

.Caption = “Hint: xlCube &” & h

.Tag = “Hint” & h


.Parameter = h

EDMenuItem h ‘procedure that disables specified menu item if the corresponding cube has been destroyed

End With


Set scoresMenuItem = xlCubeMenu.Controls.Add(Type:=msoControlButton)

With scoresMenuItem

.BeginGroup = True

.Caption = “&Scores”

.OnAction = “TheScores”

.Parameter = “Scores”

End With

Set instructMenuItem = xlCubeMenu.Controls.Add(Type:=msoControlButton)

With instructMenuItem

.BeginGroup = True

.Caption = “&Instructions”

.OnAction = “TheScores”

.Parameter = “Instructions”

End With

Set aboutMenuItem = xlCubeMenu.Controls.Add(Type:=msoControlButton)

With aboutMenuItem

.BeginGroup = True

.Caption = “&About xlCube”

.OnAction = “AboutThisGame”

End With

End Sub

This procedure adds the custom menu. Since this is an “old-style” menu, it appears on the Add-ins section of the ribbon.


I hoped you have enjoyed this series of articles on how I built this game.

xlCubeSuper An Excel Game Explained – Part5

The main explanation text for this article is in black and bold font. This is the primary procedure used in xlCubeSuper. When a cell is clicked, something happens depending on where it is and what it contains. The original documentation for this procedure is highlighted in green and other procedures used are highlighted in blue. They will be discussed in Part6.


“Shooting” is accomplished by this event procedure.


Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Excel.Range)


If Over Then Exit Sub ‘the Over variable is set to True when a game is finished


If ActiveSheet.Name = “Scores” Then Exit Sub ‘just in case you want to unhide this sheet

If Target.Font.ColorIndex > 1 Then Exit Sub ‘it already contains an “X”

If ActiveCell.Address <> Target.Address Then Exit Sub ‘if it is not a single cell selection

If Intersect(Range(“board”), Target) Is Nothing Then Exit Sub ‘if the selection is not on the board


Each of the 5 previous If-Then statement handle situations where the shot is not “correct”.



NumOfHits = Application.WorksheetFunction.Sum(Range(“sumofhits”).Value) ‘hits before entry

On Error GoTo TheEnd



Target.Value = 1 ‘entry is made

This is prehaps the most important part of this procedure, although it looks very simple. It is, but adding a 1 to the cell does several things. First, it allows the formulas described in Part4 to keep track of all of the shots and hits. So, how does an X appear on the game board? Each cell has a custom format of “X”,,, which shows an X in the cell no matter what is entered.



fShtPos = 0

TheRange = “”


The following loop checks to see whether the active cell is where any of the 7 centers of the cubes is located. If so, it will disable the hint in the menu associated with that cube and place a blue at that spot. Next, if the game is over (z=7) any hint costs will be summed and then added to the curent # of shots.


For p = 1 To 7


On Error Resume Next


tdRangeParse “centerShip” & p


If ActiveSheet.Name & Target.Address = fShtPos & TheRange Then ‘if a center of a cube has been hit


Target.Font.ColorIndex = 32

MsgBox “You just destroyed xlCube” & p & “!”, , “DESTROYED!”

Names(“cShip” & p).RefersTo = Range(“sums” & p).Value ‘changes name from reference to a value (# of hits)

Names(“centerShip” & p).Delete

Set cBar = Application.CommandBars.FindControl(Tag:=”Hint” & p)

cBar.Enabled = False ‘disables hint since corresponding cube is gone


For z = 1 To 7


If Mid(Names(“cShip” & z).RefersTo, 2, 1) = “‘” Then Exit For


If z = 7 Then

pScore = hint1Val + hint2Val + hint3Val + hint4Val + hint5Val + hint6Val + hint7Val ‘sums penalty score for hints

sScore = Range(“x15”).Value

fScore = pScore + sScore

MsgBox “The game is over! Your score is ” & fScore & “. ” & Chr(10) & Chr(13) & Level(fScore), , “GAME OVER!”

EnterInfo fScore


ThisWorkbook.Save ‘saves changes made to records table


Exit Sub

End If





Exit Sub

End If



If NumOfHits < Application.WorksheetFunction.Sum(Range(“sumofhits”).Value) Then

Target.Font.ColorIndex = 3 ‘turns red if hits > before event

End If


Finally, if the the shot is a hit, it will change the font color to red.




End Sub


Although I have not explained every aspect of this procedure, I hope that this helps!

xlCubeSuper An Excel Game Explained – Part4

This is the 4th post to explain in detail how my xlCube game application was constructed. To read the previous post, go to:

The number of hits is recorded by this formula


Where BigBoard is the 3D range representing the playing board.

The number of shots is recorded by this type of formula for each of the 7 cubes.


For explanation of the ERROR.TYPE function, see:

See the figure for each area discussed.


The following formulas use the EVALUATE function, which is an old-style xlm macro function. It can only be used in a defined name formula. If you have noticed an issue opening the game application, this may be the cause. You would then have to place the file in a trusted location to open it. They are used in the conditional formatting of the 7 hits cells.

gbool1 =ERROR.TYPE(EVALUATE(“cShip”&ROW()-5))=5

This formula is really just there in case there is no ship center for that specific ship. Previously, the user was allowed to select the number of ships to be created, so this conditional formatting formula is really a legacy feature, not affecting the game functionality.

gbool2 =NOT(ISERROR(EVALUATE(“cShip”&ROW()-5)))

If the cell for cShip1 (in row 6) has a black color from conditional formatting, it means that this formula is TRUE, cShip1 does not exist. It has been destroyed.

The next post will focus on “taking a shot”.




xlCubeSuper An Excel Game Explained – Part3

This is the 3rd post to explain in detail how my xlCube game application was constructed. To read the previous post, go to:

This is the VBA routine I developed to add 3D cube ranges to the playing board of xlCubeSuper. It generates 7 3D ranges randomly with sizes ranging from 3x3x3 to 15x15x15.

Sub tdAddNamedRanges()

Randomize ‘ Initialize random-number generator

For s = 1 To 7

‘set x,y, and z values to fall within limits determined by cube size

x = 1 + Int(Rnd() * (20 – (2 * s)))

y = 1 + Int(Rnd() * (20 – (2 * s)))

z = 1 + Int(Rnd() * (20 – (2 * s)))

‘create R1C1 style formula strings

cShipStr = “='” & z & “:” & z + (2 * s) & “‘!R” & x & “C” & y & “:R” & x + (2 * s) & “C” & y + (2 * s)

centerShipStr = “='” & z + s & “‘!R” & x + s & “C” & y + s

‘create names for cube 3D references and the centers of each cube

matchVar = False

With ThisWorkbook.Names

.Add Name:=”cShip” & s, RefersToR1C1:=cShipStr, Visible:=False

.Add Name:=”centerShip” & s, RefersToR1C1:=centerShipStr, Visible:=False

End With

If s > 1 Then

For m = 1 To s – 1

If Names(“centership” & m).RefersTo = Names(“centership” & s).RefersTo Then

matchVar = True

End If


End If

If matchVar Then

s = s – 1

End If


End Sub

The first statement in the VBA procedure uses RANDOMIZE to create a numeric seed that will be used by the RND function to generate a random number.

Inside the For-Next statement, which sets the variable “s” to a value from 1 to 7, the xyz coordinates for each cube are generated as follows:

x = 1 + Int(Rnd() * (20 – (2 * s)))

y = 1 + Int(Rnd() * (20 – (2 * s)))

z = 1 + Int(Rnd() * (20 – (2 * s)))

The numbers generated by these fomulas keep the cube on the board, depending on the value of “s”. The z coordinate is for the worksheets included in tne board and the xy coordinates are for the cells.

Then, for each value of “s”, the 3D cubical range and the center of each cube are generated with these formulas in R1C1 format.

cShipStr = “='” & z & “:” & z + (2 * s) & “‘!R” & x & “C” & y & “:R” & x + (2 * s) & “C” & y + (2 * s)

centerShipStr = “='” & z + s & “‘!R” & x + s & “C” & y + s

When they are saved as defined name formulas using the following code,

With ThisWorkbook.Names

.Add Name:=”cShip” & s, RefersToR1C1:=cShipStr, Visible:=False

.Add Name:=”centerShip” & s, RefersToR1C1:=centerShipStr, Visible:=False

End With

the formulas are converted by Excel into A1 format.

Originally, this was all of the code for this process. What I had ignored what the fact that two different cubes could have the exact same center. During all of the testing/playing of this game over the years, that scenario was never recognized as having occurred. But the current version, with 7 cubes, had this happen several times in early testing. So, I came up with this solution to correct this issue.

If s > 1 Then

For m = 1 To s – 1

If Names(“centership” & m).RefersTo = Names(“centership” & s).RefersTo Then

matchVar = True

End If


End If

If matchVar Then

s = s – 1

End If

A key part to this code is

Names(“centership” & m).RefersTo = Names(“centership” & s).RefersTo

which compares the currently added formula to each previous formula added. If this statement is TRUE, then matchVar is set to TRUE. Then,

If matchVar Then

s = s – 1

End If

which decrements “s” by 1, effectively rerunning the previously generated 3D formula until an unique center is produced.

The next post will discuss the worksheet formulas used in this game.






xlCubeSuper An Excel Game Explained – Part1

I have just recently updated/modified my xlCube game that I first started on 20 years ago. The main modification is that it now has 7 cubes that must be destroyed before the game is over. For those who have never played the game, the previous version can be found at:

The new game is called xlCubeSuper. And, like the previous release, I encourage you to dig into the details of how this application was constructed. But, I know that your time is precious, and you may feel that this would not be an effective use of your Excel time. So, this time I am going to explain in detail all of the tricks and techniques used in the making of this game. In Part 1, I am only making it available to you. The explanation will come in subsequent posts. In the meantime, have fun with it.
