Yesterday, I talked about how you don’t have to know how to code in order to highly leverage VBA. All you need to know is how to Google, Cut, and Paste. As discussed then, I ‘volunteered’ KV under pain of exposure to empty the contents of his secret satchel onto the virtual table, so that we can rummage through it. So without further ado, please put your hands together and give a warm Chandoo welcome to secret agent KV.
[Secret transmission starts…]
Hello, this is my first guest post on Chandoo.org (or any Excel website for that matter), and I will try to keep it simple, but useful for our readers.
I have been using spreadsheets since 1990, and Excel since 1995 – which sort of makes me a veteran in this sphere of business applications 🙂
One of my favorite topics in Excel is – “How can I make my day-to-day tasks in Excel easier and faster ?”. In fact, this is a topic that I think about in everything to do with computers.
There are many ways one can do this in Excel, but among the more effective and scalable ones, is storing commonly used macros in your Personal Macro Workbook.
This post is about some of the stuff that I have put in my Personal Macro Workbook over the years. You can read more about how to set up a Personal Macro Workbook, in this excellent tutorial on Ron de Bruin’s website. Like nuclear war, It’s a one-time exercise. And you can easily port it to any other computers that you use – or even share it with your friends and allied spooks.
This is the first bunch of macros which I use most frequently. Hopefully I will get a chance to post some more if this post is found to be good enough 🙂
So here goes.
1: Find the value of ActiveCell within selection, or in the whole sheet
This is a very useful macro which helps to search for the value in the ActiveCell within the selected range or the whole worksheet (if only ActiveCell is selected).
Sub SearchOnActiveCellContents()
' Keyboard Shortcut: Ctrl+Shift+G
On Error GoTo NotFound
If Selection.Cells.Count > 1 Then
Selection.Cells.Find _
(What:=ActiveCell.Value, After:=ActiveCell, LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate
Else
Cells.Find _
(What:=ActiveCell.Value, After:=ActiveCell, LookIn:=xlValues, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False).Activate
End If
Exit Sub
NotFound:
MsgBox "No cells found with this cell's contents"
End Sub
As you will notice, the macro checks whether the selection is 1 cell or multiple cells, and accordingly executes the Cells.Find command.
2: Filter on value NOT equal to ActiveCell value
This is another handy macro, which filters the current column based on the value of the active cell, except that the filter is applied as “show records NOT equal to the value of the active cell”
The macro itself is a fairly simple one-line command :
Sub AutoFilterSelectionNOT()
' Keyboard Shortcut: Ctrl+Shift+K
Dim lField As Long
lField = ActiveCell.Column - ActiveCell.CurrentRegion.Column + 1
If TypeName(Selection) <> "Range" Then Exit Sub
Selection.AutoFilter Field:=lField, Criteria1:="<>" & ActiveCell.Value
End Sub
3. Show or Hide zeros in active sheet
This macro toggles the display of zero-value cells on the active sheet.
Sub Hide_Zeros()
' Keyboard Shortcut: Ctrl+Shift+Z
If TypeName(Selection) <> "Range" Then Exit Sub
ActiveWindow.DisplayZeros = Not ActiveWindow.DisplayZeros
End Sub
4: Show or Hide page-breaks in active sheet
This macro toggles the display of page-breaks on the active sheet.
Sub ShowHidePageBreaks()
' Keyboard Shortcut: Ctrl+Shift+J
If TypeName(Selection) <> "Range" Then Exit Sub
ActiveSheet.DisplayPageBreaks = Not
ActiveSheet.DisplayPageBreaks
End Sub
As the name suggests , this macro will show or hide the display of page breaks on the active sheet.
5: Display the 'GoTo special' xldialog
Quite often I find myself needing to use the GoTo Special command.
Of course, you can do it the way it was designed in Excel – press F5 to display the GoTo dialog box, and click on the Special… button. This takes one keystroke and a mouse-click; or 3 keystrokes (if you don’t use the mouse) 🙂
Or you can display the Goto > Special… dialog box (using a macro) with just 1 click of the mouse or 2 keystrokes (if you pin it on the QAT) !
Sub xlSelectSpecial()
On Error GoTo NotFound
If Selection.Cells.Count = 1 Then
MsgBox "Select more than 1 cell...", vbExclamation, "Select more cells..."
Exit Sub
End If
Application.Dialogs(xlDialogSelectSpecial).Show
Exit Sub
NotFound:
myMsgText = "No such cells found"
myTitle = "Not found"
myConfig = vbOKOnly + vbExclamation
myMessage = MsgBox(myMsgText, myConfig, myTitle)
End Sub
As you will notice, the macro has an error-checking line in case the type of ‘special cell’ you selected is not found. E.g. if you’re looking for blank cells in the selection, and all the cells in it are non-blank, the macro will display a message accordingly.
The macro also checks whether more than one cell is selected before executing the dialog. The reason for this is that if a single cell is selected, many of the options in the GoTo Special dialog box will execute on the entire ‘UsedRange’ of the spreadsheet, instead of the selected range.
If you wish, you can comment out the If … End If construct and test the macro to see what I mean.
6: Zoom-in / Zoom-out
These macros zoom in or zoom out on the worksheet, in increments of 5%.
Sub MyZoomIn()
' Keyboard Shortcut: Ctrl+E
Dim ZP As Integer
ZP = ActiveWindow.Zoom
If ZP >= 400 Then
ZP = 400
Else
ZP = ZP + 5
End If
ActiveWindow.Zoom = ZP
End Sub
Sub MyZoomOut()
' Keyboard Shortcut: Ctrl+Shift+E
Dim ZP As Integer
ZP = ActiveWindow.Zoom
If ZP <= 10 Then
ZP = 10
Else
ZP = ZP - 5
End If
ActiveWindow.Zoom = ZP
End Sub
As you will notice, will increase or decrease the zoom percentage by 5 points each time the macro is executed. The If… Then… Else… constructs are there to prevent an error if the current zoom percentage is already at the maximum or minimum level, when the macro is executed.
That’s all for this post from my side. I hope you will find it useful.
I welcome comments, suggestions for improvement & criticisms from readers on this topic, and the macros I have shared in this post.

Hey, thanks KV for sharing those shortcut-charged shortcuts. I look forward to torturing some more of that ill-gotten wisdom out of you. (While I don’t condone torture, I hate inefficient use of Excel even more. So while it’s going to hurt you more than me, it’s for the greater good.)

first solution for AND
The two numbers are in A1 and B1
= SUBSTITUTE (SUBSTITUTE (A1+B1*9*9, 9, 1), 8, 0)
regards
Stef@n
next solution for OR
=1*SUBSTITUTE (A1+A2;2;1)
regards
Stef@n
last solution for XOR
=1*SUBSTITUTE (A1+A2;2;0)
regards
Stef@n
Or you could make use of the VBA logical operators!
Define the following as custom functions
Public Function BITXOR(x As Long, y As Long)
BITXOR = x Xor y
End Function
Public Function BITAND(x As Long, y As Long)
BITAND = x And y
End Function
Public Function BITOR(x As Long, y As Long)
BITOR = x Or y
End Function
and then use them such:
A B =BITOR(A,B) =BITAND(A,B) =BITXOR(A,B)
0101 0100 0101 0100 0001
an another solution for AND
=1*SUBSTITUTE (SUBSTITUTE (A1+A2;1;0);2;1)
note:
the binary numbers are in A1 and A2 !

Stef@n
I was obviously playing hooky at the beach during the bit-wise math lesson – you lost me at “Understanding bit-wise operations” 🙂
After looking at the above solutions, I find my solution silly, but still:
For the following formulae,
Row 1: headers,
Row 2: OR
Row 3: AND
Row 4: XOR
Column 1: Input 1
Column 2: Input 2
Column 3: Result
OR
{=SUM(IF(MID(A2,ROW(OFFSET($A$1,0,0,LEN(A2),1)),1)+MID(B2,ROW(OFFSET($A$1,0,0,LEN(B2),1)),1)>0,1,0)*10^(LEN(A2)-ROW(OFFSET($A$1,0,0,LEN(B2),1))))}
AND
{=SUM(IF(MID(A3,ROW(OFFSET($A$1,0,0,LEN(A3),1)),1)+MID(B3,ROW(OFFSET($A$1,0,0,LEN(B3),1)),1)=2,1,0)*10^(LEN(A3)-ROW(OFFSET($A$1,0,0,LEN(B3),1))))}
XOR
{=SUM(IF(MID(A4,ROW(OFFSET($A$1,0,0,LEN(A4),1)),1)+MID(B4,ROW(OFFSET($A$1,0,0,LEN(B4),1)),1)=1,1,0)*10^(LEN(A4)-ROW(OFFSET($A$1,0,0,LEN(B4),1))))}
@Anup
Please don't consider your solution silly
Firstly, You are the 3rd person to submit an answer
Secondly, The best formula/function is the one that you know and understand.
I think I have a very tedious solution, which people won't have the patience to do except in small numbers.
I used the same problem setup as "Anup Agarwal"
AND =IF(AND(MID(B2,1,1)="1",MID(C2,1,1)="1"),1,0)&IF(AND(MID(B2,2,1)="1",MID(C2,2,1)="1"),1,0)&IF(AND(MID(B2,3,1)="1",MID(C2,3,1)="1"),1,0)&IF(AND(MID(B2,4,1)="1",MID(C2,4,1)="1"),1,0)
OR =IF(OR(MID(B3,1,1)="1",MID(C3,1,1)="1"),1,0)&IF(OR(MID(B3,2,1)="1",MID(C3,2,1)="1"),1,0)&IF(OR(MID(B3,3,1)="1",MID(C3,3,1)="1"),1,0)&IF(OR(MID(B3,4,1)="1",MID(C3,4,1)="1"),1,0)
=IF(OR(AND(MID(B4,1,1)="1",MID(C4,1,1)="0"),AND(MID(B4,1,1)="0",MID(C4,1,1)="1")),1,0)&IF(OR(AND(MID(B4,2,1)="1",MID(C4,2,1)="0"),AND(MID(B4,2,1)="0",MID(C4,2,1)="1")),1,0)&IF(OR(AND(MID(B4,3,1)="1",MID(C4,3,1)="0"),AND(MID(B4,3,1)="0",MID(C4,3,1)="1")),1,0)&IF(OR(AND(MID(B4,4,1)="1",MID(C4,4,1)="0"),AND(MID(B4,4,1)="0",MID(C4,4,1)="1")),1,0)
Sorry my last post was totally messed up
AND
=IF(AND(MID(B2,1,1)="1",MID(C2,1,1)="1"),1,0)&IF(AND(MID(B2,2,1)="1",MID(C2,2,1)="1"),1,0)&IF(AND(MID(B2,3,1)="1",MID(C2,3,1)="1"),1,0)&IF(AND(MID(B2,4,1)="1",MID(C2,4,1)="1"),1,0)
OR
=IF(OR(MID(B3,1,1)="1",MID(C3,1,1)="1"),1,0)&IF(OR(MID(B3,2,1)="1",MID(C3,2,1)="1"),1,0)&IF(OR(MID(B3,3,1)="1",MID(C3,3,1)="1"),1,0)&IF(OR(MID(B3,4,1)="1",MID(C3,4,1)="1"),1,0)
XOR
=IF(OR(AND(MID(B4,1,1)="1",MID(C4,1,1)="0"),AND(MID(B4,1,1)="0",MID(C4,1,1)="1")),1,0)&IF(OR(AND(MID(B4,2,1)="1",MID(C4,2,1)="0"),AND(MID(B4,2,1)="0",MID(C4,2,1)="1")),1,0)&IF(OR(AND(MID(B4,3,1)="1",MID(C4,3,1)="0"),AND(MID(B4,3,1)="0",MID(C4,3,1)="1")),1,0)&IF(OR(AND(MID(B4,4,1)="1",MID(C4,4,1)="0"),AND(MID(B4,4,1)="0",MID(C4,4,1)="1")),1,0)
@stefan,
I just couldn't get your solutions to work.
01010101010 + 01010101110 = 02020210120
what am i doing wrong?
@anup
...I got yours to work!
@Stephen - I get the same, but Stef@an's second solution for AND does work (at least for the test cases I used)
@ Stephen / Rich
yes , you are right ! - only this works:
OR
=1*SUBSTITUTE (A1+A2;2;1)
XOR
=1*SUBSTITUTE (A1+A2;2;0)
AND
=1*SUBSTITUTE (SUBSTITUTE (A1+A2;1;0);2;1)
@Stef@n - You're answer is really smart, I never knew about the substitute function before. Great Work!
Thx Michael 🙂
yes - it is simply easy 😉
if you add 1 and 1 - excel calculate 2
and then you have to substitute the 2 - new = 0 respectively 1
Here is a good resource for people wanting to learn binary and hexadecimal.
http://justwebware.com/bitwise/bitwise.html
Three that weren't asked for:
NOT
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1+A2,0,3),1,0),3,1)
EQV
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1+A2,0,3),2,3),1,0),3,1)
IMP
=SUBSTITUTE(SUBSTITUTE(A1+SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A2,0,3),1,0),3,1),0,1),2,0)
(was using Daniel Ferry's bitwise file to verify against)
@ Kyle
Not only takes one parameter and inverts 0 -1 and 1-0
Took out the +A2
=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,0,3),1,0),3,1)
Great solutions!
I'll add two:
NAND =1*SUBSTITUTE (A1+A2,2,0)
NOR=1*SUBSTITUTE(SUBSTITUTE (SUBSTITUTE(A1+A2,0,2),1,0),2,1)
This will work for binary numbers of any size (although the text format mask will have to have as many zeroes as there are digits in the longest addend)
Assume binary #s are in C35 & C36, then add and format as text in C37:
=TEXT(C36+C35,"000000000000")
-sum- = 101112211112
AND - SUBSTITUTE 0s for 1s in -sum-, then sub 1s for 2s
=SUBSTITUTE(SUBSTITUTE(C37,"1","0"),"2","1")
OR - sub 1s for 2s in -sum-
=SUBSTITUTE(C37,"2","1")
XOR - sub 0s for 2s in -sum-
=SUBSTITUTE(C37,"2","0")
Just wandered by:
AND:
=SUBSTITUTE(A1+A2,1,0)/2
Clever, Shane. I like that.

Hi Chandoo,
I am not (yet) really into bitwise calculation, but I am looking for a way to speed up my vba calculation with very big numbers. Would is ben convenient to use bitwise notation for this?
Best regards,
Ronald (the Netherlands)
p.s. love your country!
@Ronald
I'd suggest asking this in the Chandoo.org Forums
