3. New Excel Formula Crash Course – Coming this Wednesday, 17 August
Excel formulas have confused one too many of us. It took me more than an year to understand simple formulas like IF & VLOOKUP and use them effectively. That is why, I created this course. It is easy to follow, simple to digest and yet power-packed with lots of ideas & information. The aim of this course is to make you a master of Excel formulas in 31 days. The course has 6 modules,
- Formula Basics
- Lookup Formulas
- Text Formulas
- Date & Time Formulas
- Advanced Formulas
- Errors, Auditing & More
For more information, please watch this short video:
4. Excel School Prices Going up!
I have created Excel School online training program in Jan 2010. Ever since, we have trained more than 1500 people thru this program. Every week, I get emails from our students telling me how much they have gained from this program and how they are able to impress everyone at their workplace. During the same time, I have been adding new content to this program to make it perfect. And now time has come to hike the course fees to match the value it delivers. Starting Monday, August 29, Excel School prices will be going up. See the below table to understand new prices. And join us now if you want to save money.

5. Recommended Live Training: Excel Power Analyst Bootcamp in Washington DC, USA on September 19th
My good friend, teacher & fellow Excel blogger, Mike Alexander runs Excel Power Analyst Bootcamps every year. This year, he is doing it on September 19 & 20 in Alexandria, VA (few minutes away from Washington DC). Now, few days back, Mike emailed and asked if I can suggest this program to my readers. I agree with pretty much everything Mike does (except the heart-attack prone bacon recipes he suggests). So here I am recommending his course. I have attended a few webinars Mike did and I can vouch for the amazing knowledge he shares with us. He is a natural teacher and you are going to love the time you spend with him. So if you happen to be near Alexandria (VA) and want to learn Excel, then go for his bootcamp.
Click here to sign-up for Mike’s Excel Power Analyst Bootcamp.
PS: I do not get any money out of this recommendation. However, Mike promised to do a guest lecture in our upcoming VBA Class. But I would have recommended this bootcamp even otherwise 🙂
End of Announcements!
I wish you an awesome week ahead 🙂

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.
