This week we are celebrating Your Week @ PHD. That means you get to read the excel tips shared by other readers of this blog.
Unhide all the sheets using simple macro by Kat
My single favourite simple macro ever – to fill in the gap that Excel leaves. Unhiding -all- hidden tabs in a workbook at once. I install it in the personal.xls workbook, and save myself hours of clicking.
Sub Unhide_All_Sheets() Dim wsSheet As Worksheet For Each wsSheet In ActiveWorkbook.Worksheets wsSheet.Visible = xlSheetVisible Next wsSheet End Sub
A KPI Dashboard using VBA and Charts by David
After learning a whole lot over the past few months from this site and others (so many I can’t even remember right now – but I will make a list soon of where I found things), I constructed a KPI spreadsheet (see link below). This spreadsheet allows our institution to create standardized KPI reports for university consumption.
I attempted to keep the colors muted even though I chose school colors (from the publishing guide) for the actual graph.
Features
The chart is dynamically configured in numerous ways. The user can control the title (via cell entry on left), color of bars (via color of data labels), number format (via number format of the first data cell), and the display and printing of the trend line. The KPI name comes from the sheet, and the vertical axis is determined based on the data (I find the maximum value and divide by 4).
To-dos
I would like the user to be able to enter new descriptive items via a form with the option to include variables (KPI_Name, KPI_Category, etc.). I would like the user to be able to include more than one chart on a page (some KPIs actually need to track parts of the whole).
I am sure there are more features I will think of as time goes on but I wanted to let others see this and hopefully be able to incorporate it into their/your own work. The file is available here: http://dl.getdropbox.com/u/749941/KPIs_PHD.xlsm. Hopefully I will be starting a blog soon to talk more about what we are doing here with excel and other products.
Using Find Dialog to Solve a Tricky Problem by Christy Lee
Introduction:
On a project I recently worked, we crunched several hundred (about 400) rows of data. The creator of the original document did not have any way to foresee the life this project would take on! So…there was only one field for ‘Name’ which contained the names of the team members for the corresponding step of the overall project.
Challenge:
As the project progressed, an individual may be added to multiple task teams. So, your name might be one of three in four records, one of ten in fifteen records, etc. Also, the team members could be added on the fly…you see how the complications arise quickly! Oh, and the project was run on three continents in four countries….
Each person was responsible for updating their pertinent information. Because of the complexity of that one name cell, filtering and sorting became cumbersome.
Solution:
Hide all rows except for the header row.
Do a search on your name (fortunately, in about three dozen team members, we had no duplicate last names!)
When the search results dialog comes up, select all of the records (select first, shift+select last)
Go to Format>Row>Show.
Whoo Hoo! There are all (and ONLY) the records that belong to you.
Array Formulas to the Rescue by Rajinikanth
This is the formula to find out Employees first login time and last logout time for the day.
Example : Suppose employee table is starting form Column B
then the table looks like :
Name Code
1001 rajinikanth
1002 srinivas
1003 vardhan
and the Login Data is starting from Column G in a sheet
Then The formula for First login :
{=1/MAX((B8=$G$7:$G$15)*($H$7:$H$15<>0)*(1/$H$7:$H$15))}
and the formula for Last Logout :
{=MAX(($G$7:$G$15=B7)*($I$7:$I$15))}
A Big Warm Lovely Heartfelt Thank you to Kat, David, Christy and Rajinikanth. You are truly wonderful.

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!

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.
How to convert a figure like 870.70 into 870 but 871.70 into 880 using excel formula ? Please help.
