Here is a formula challenge for you.
![How many values are common in 2 lists [homework]](https://img.chandoo.org/hw/formula-size-of-common-values-in-2-lists.png "How many values are common in 2 lists [homework]")
Lets say we have 2 lists of values in A1:A10 & B1:B10
Now, how do you find the number of common values in both lists?
We just want the count, not list of common values it self.
Go ahead and figure out the formula and post your answers here.
Bonus challenges:
- Write the formula if 2 lists have non-numeric values (text for example) ?
- Write the formula if 2 lists are not of same size (A1:A10 and B1:B15 for example) ?
- Write the formula if we have 3 lists (all same size, numeric values) ?
Go ahead and share your answers. I am eager to see what you will come up with.
PS: For some inspiration, check out this forum discussion.
PPS: If you just want to highlight the common values, see this.

I've just taught yesterday to a colleague of mine how to convert amounts in local currency into another by pasting special the ROE.
great thing to know !!!
Chandoo - this is such a great trick and helps save time. If you don't use this shortcut, you have to take can create a formula where =(ref cell /100), copy that all the way down, covert it to a percentage and then copy/paste values to the original column. This does it all much faster. Nice job!
I was just asking peers yesterday if anyone know if an easy way to do this, I've been editing each cell and adding a % manually vs setting the cell to Percentage for months and just finally reached my wits end. What perfect timing! Thanks, great tip!
If it's just appearance you care about, another alternative is to use this custom number format:
0"%"
By adding the percent sign in quotes, it gets treated as text and won't do what you warned about here: "You can not just format the cells to % format either, excel shows 23 as 2300% then."
Dear Jon S. You are the reason I love the internet. 3 year old comments making my life easier.
Thank you.
Here is a quicker protocol.
Enter 10000% into the extra cell, copy this cell, select the range you need to convert to percentages, and use paste special > divide. Since the Paste > All option is selected, it not only divides by 10000% (i.e. 100), it also applies the % format to the cells being pasted on.
@Martin: That is another very good use of Divide / Multiply operations.
@Tony, @Jody: Thank you 🙂
@Jon S: Good one...
@Jon... now why didnt I think of that.. Excellent
Thank You so much. it is really helped me.
Big help...Thanks
Thanks. That really saved me a lot of time!
Is Show Formulas is turned on in the Formula Ribbon, it will stay in decimal form until that is turned off. Drove me batty for an hour until I just figured it out.
