Welcome back. In final part of Making a Customer Service Dashboard using Excel let us learn how to add macros & VBA code that makes our dashboard interactive.

Adding Macros & Final touches
As you can see, there are 2 important macros in this dashboard.
#1: Capturing selected item details
Whenever user clicks on an item in the detail area to compare, there is a small macro running behind that tells us what item is selected so that we can trigger our calculations and conditional formats. How does it work?
Simpler than we think!
We use a macro called as Worksheet_SelectionChange.

Understanding Event Macros
There is a special type of macros in Excel called as Event macros (or simple events). For example, if you want to do something whenever user selects cell D14, you can use an event macro. Excel offers various events so that we can initiate certain actions when user selects a cell, clicks on a hyperlink, activates a worksheet, updates a pivot table or finishes some calculation etc.
In our case, we wanted to change the comparison options based on what is selected by user. So we use an event called as Worksheet_SelectionChange
When you add a selection change macro to any worksheet, excel runs whenever you select a cell in that worksheet. Lets look a simple worksheet selection change macro to understand this:
The code for above event:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
[valSelection] = "You have selected " & Target.Address
End Sub
The range valSelection is linked to text box that you saw in demo.
Event macro in our Customer Service Dashboard
In our dashboard, we have one additional challenge. We need to run our event macro only if one of the two lists (rndSel1 & rngSel2).
This is where we use an additional feature of VBA, Application.intersect() formula. This checks whether given two ranges overlap and if so, returns the region in overlap.
Lets look at our event macro:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'This macro is triggered whenever any cell is selected in the Dashboard worksheet
'Step #1: If user clicks on a blank cell then do nothing
If ActiveCell.Value = "" Then Exit Sub
'Step#2: See if the selected cell is in left column
If Not (Application.Intersect(ActiveCell, Range("rngSel1").Cells) Is Nothing) Then
'If so, then call setOption1 macro
Call setOption1
'Step #3: See if the selectd cell is in right column
ElseIf Not (Application.Intersect(ActiveCell, Range("rngSel2").Cells) Is Nothing) Then
'If so, then call setOption2 macro
Call setOption2
End If
End Sub
If you examine the comments, most of what it does should be obvious.
#2: Showing & Hiding help messages
Adding help feature to complex dashboards makes life simpler for end users. So I always recommend it to my students. But how easy is it to add help?
Well, easier than you think. Just follow below steps:
- Add help messages to your dashboard using drawing shape > bubbles
- Once all the messages are added, just select all of them and group (right click > group)
- Select the group and using name box in Excel, give it a name, in our case the name is boxHelp
- In a new module, Write a macro (lets call it showHideHelp) to display and hide the boxHelp group.
- Now add a small text box with label “Help” on it.
- Assign the macro to this help text. (right click on the group, assign macro)
But what do we put in showHideHelp macro?
Simple, When user clicks on Help text, we will just toggle the visibility of boxHelp group using code like this:
ActiveSheet.Shapes.Range(Array("boxHelp")).Visible = Not ActiveSheet.Shapes.Range(Array("boxHelp")).Visible
The Not portion toggles the visibility, thus when you click on help button the help gets turned on if it is off (and vice-a-versa)

Future directions for this dashboard…
I am happy how this turned out so far. That said, we can make a few advancements to it like:
- Using Excel 2010 slicers to make the selection of items in comparison area.
- Adding ability to export dashboard as PDF or PPT
- Adding qualitative comments to dashboard (automated a la tweetboard or manual) so that managers can understand what caused the change.
- Adding customizable time windows. Currently the dashboard shows any 4 week window, but it can become even more powerful by adding custom start and end dates.

20 Responses to “Untrimmable Spaces – Excel Formula”
Hi Chandoo,
First of all, HAPPY NEW YEAR!!! Wish you and your family another fruitful year ahead.
To answer your question: Power Query is the best way to trim. 🙂
Btw, if Power Query is not available, then formula would absolutely do... but did you forget to mention also Char 32?
One more question: Is the trailing minus meant to be a negative number? Maybe only the sender knows... 🙂
Cheers,
I just see your PQ way, it is amazing, I think it is the most simple way.
No idea how it did it?
I know these spaces can be a real pain but these days I advise Excel users to learn and use Flash Fill and that will learn what to do pretty quickly.
Highlight range to be cleaned. Then, in Replace, hold down the Alt key and type 0160. Replace with nothing.
I accomplished this by writing a macro to go through all the possible unprintable characters. Looped through the range.
@Steve
Brute force works just as well, its just slower
I use a different method here. First, I will copy the data from Excel and paste it in a notepad. In Notepad, I will do a Find Blanks (Space " ") and Replace (Empty) with nothing.
Then you can copy the data from Notepad and paste it back to Excel which will be a perfect number as you desire.
But Thanks for the formula. Its probably the 2nd out of 8 tricks as Chandoo mentioned. Waiting for the rest among 8 from other users 🙂
Hi....
You don't always need notepad for that. I use the Find/Replace is Excel works just fine.
I don't understand the x's. Why weren't they removed in the formula? Or are they part of some sort of numeric formatting that I'm not familiar with? I saw how you handled the non-breaking spaces and the dashes, but am confused about what role the x's played in all this.
Thanks!
Hi Andrew ,
The xs have been used solely to demarcate the actual data text ; thus , without the x in place at the end of text , as in :
x 4,124,500.00 x
it would be impossible to know that there are unwanted trailing characters , in this case , after the last 0.
These xs are not part of the original data text , nor are they used in the formulae ; they are put in only so that readers can visualize the individual items of data as they are in practice. Think of them as imaginary delimiters.
Oh, that makes sense! Thank you for the explanation. I had a feeling it was something along those lines.
You can type this character using the Keys Alt+0160.
Very useful to replace this Character using Find and Select resource.
For many years, my jobs have included ETL tasks and I built this macro to help long, long ago. I tweak it every now and again. Many co-workers, past and present, have it wired to a button on their toolbar.
Sub Clean_and_Trim()
'CAUTION: Strips leading zeroes -- do not use on zipcodes, etc.
If Application.Calculation = xlCalculationAutomatic Then
Application.Calculation = xlCalculationManual
Revert = 1
ElseIf Application.Calculation = xlCalculationManual Then
Revert = 0
End If
For Each Cell In Selection
For x = Len(Cell.Value) To 1 Step -1
If Asc(Mid(Cell.Value, x, 1)) = 160 Then
Cell.Replace What:=Chr(160), Replacement:=" ", LookAt:=xlPart, MatchCase:=True
End If
If Asc(Mid(Cell.Value, x, 1)) = 32 Then
Cell.Replace What:=Chr(32), Replacement:=" ", LookAt:=xlPart, MatchCase:=True
End If
Next x
If Cell.Value "" Then
Cell.Value = Application.Clean(Application.Trim(Cell.Value))
End If
Next
If Revert = 1 Then
Application.Calculation = xlCalculationAutomatic
ElseIf Revert = 0 Then
Application.Calculation = xlCalculationManual
End If
End Sub
This is awesome! What if you have several characters you need to have removed? What would be the easiest way as I can imagine there are several ways.?
# - 35
$ - 36
- 62
/ - 47
, - 44
. - 46
" - 34
: - 58
This is typical case of a Fitbit data export to Csv file. Each number has CHAR160 as thousand separator.. how smart Fitbit, thank you 😉
By the way, i prefer to copy the character, and use find and replace.
Sometimes it happens if you copy a table from outlook and paste it in excel. When you apply formula on those cells you will get error. What i use to do is
copy one character that looks like space,
select the entire range,
go to Find and replace,
Paste the copied character in Find option
Leave the replace option unfilled..
click on replace all..
All the errors shall be converted in to proper values..
Process looks lengthier.. but it is one of the simplest method
If Clean, Trim, and Substitute, or Find and Replace does not complete the job, I usually enter a value of 1 in an empty cell. Copy the Value of 1, Highlight the range of text numbers, and Paste Special, Values, Multiply. This site is great!
