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.

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!
Eric~
Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
