In the past here at Chandoo.org and at many many other sites, people have asked the question “How can I display a number Multiplied or Divided by 10, 100, 1000, 1000000 etc, but still have the cell maintain the original number for use in subsequent calculations“.
Typically the answer has been limited to “It can’t be done” or “It can only be done in multiples of 1000”.
Well thanks to a tip I picked up from Kyle who responded to a post here at Chandoo.org they are all wrong.
It is possible to Multiply or Divide any cell contents by any power of 10 using Custom Number Formats !
That is:
How does this work:
When using custom number format we have two possibilities to modify the display number
- Use a Comma to divide by 1000; or
- Use a % to Multiply by 100
So using a combination of these any power of 10 can be obtained.
So using the correct combination of , and % can result in any power of 10 multiplier we require.
The problem is that using a % adds a % to the number!
The trick which Kyle added is that adding a Ctrl J to the Custom Number format allows us to hide the % signs on a second row of text, then by adjusting the cell to have word wrap and adjusting the row height the second row is not visible.
The Ctrl J must be added after the ,’s and before the %’s
So using the examples above the table is:
The Ctrl J adds a Carriage Return, chr(10), to the Format String.
Finally after applying the Custom Number Format the Cell must be edited to enable Word Wrap.
Select the Cells with the custom Formats, Ctrl 1, Alignment
You can see the hidden % symbols if you increase the Row Height.
Combination with Regular Custom Formats
These Custom Number Formats can of course still be combined with regular Custom Number Formats, just make sure that the Ctrl J is inserted before the % signs:
No Loss of the Cells Value
It is also worth noting that the original number is still maintained internally in the cell and that cells dependent on the cells don’t have to adjust for the display value.
Multi Line Formats
By extension we can now use this technique to add multiple Lines of Text to a Custom Number Format

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.
