Last week, we had our very first quiz – “How well do you know your LOOKUPs?“. I hope you have enjoyed it.
Today lets understand the answers & explanations for this quiz.
First a summary of results (and controversies):
More than 3,200 people attempted the quiz. Roughly 45% of you got correct answers. That said there were 4 questions where 90% of you made mistakes. This is mainly because these questions & answer choices were ambiguous. As this is the first time I ran a quiz on Chandoo.org, it was a learning experience for me too. I promise to keep the questions & answer choices clearer next time 🙂
*Questions that are ambiguous are marked with a * below.
Here are the answers & explanations this quiz.
If your lookup table is in ascending order, then you can omit 4th parameter and VLOOKUP will find either exact or approximate match.
We use 4th parameter as FALSE when our list may not be in any particular sort order and we are looking for exact matches.
So the answer is When my lookup list is not in any particular sort order

We can check whether a value is present in a list or not using any of below formulas.
COUNTIF / COUNTIFS
- COUNTIF(range, value you are looking) will be >0 if value is available.
- Introduction to COUNTIF formula
VLOOKUP
- VLOOKUP(value you are looking, range, 1,false) will not be an error if value is available
SUMPRODUCT
- SUMPRODUCT(–(range=value you are looking)) will be >0
- Introduction to SUMPRODUCT formula
MATCH
- MATCH(value you are looking, range,0) will not be an error
- Introduction to MATCH formula
VLOOKUP will always find the first match (assuming you specified FALSE in last parameter).

We all want a world without traffic, crying babies & error messages. Alas, there are no Excel formulas for first 2, but we can suppress error messages for sure, by using any of below formulas:
- IFERROR
- ISERROR
- ISNA
- IFNA (new in Excel 2013)
Invoice ID, Customer ID, Amount, Due DateNow, you want to lookup the invoice ID for a given Customer ID. Which of below formulas you would use? Assume that your list is not in any particular order and there are no duplicate customer IDs.Although VLOOKUP is very powerful, it has one limitation. It can only search in left most column and get values from columns to right. To lookup on a column in middle and get values from either left or right, we can use below alternatives.
INDEX + MATCH formulas
- =INDEX(invoiceIDs, MATCH(thisID, customerIDs, 0))
- More on this technique
OFFSET + MATCH formulas
- =OFFSET(invoiceIDs, MATCH(thisID, customerIDs, 0),0,1,1)
- More on this technique, OFFSET formula explained
VLOOKUP + CHOOSE formulas
- =VLOOKUP(thisID,CHOOSE({2,1},invoiceIDs, customerIDs), 2, FALSE)
- More on this technique
To find the last invoice and its amount, we need to few ingredients:
- Know how many invoices are there for given invoice number
- A helper column with invoice counts up to that point
For above data, you can insert a column between A&B and use it as helper column. Write this formula in it (and fill down)
=A1&”-“&COUNTIF($A$1:A1,A1)
This will tell us how many times each invoice number is repeated up to that point.
Now, use the VLOOKUP formula to find last invoice’s amount like this:
=VLOOKUP(this_invoice&”-“&COUNTIF(A1:A100, this_invoice), B1:C100, 2, false)
Related: Finding 2nd, 3rd … matches using VLOOKUP.
Nah, it will return #N/A error.
Q8. You have a list of employee names & their salary details.
Employee name, Salary, Special Allowance, Travel Allowance, Bonus
in 5 columns – A1:E100.
Your friend gave you below VLOOKUP formula
=SUMPRODUCT(VLOOKUP("Joyce", A1:E100, {2,3,4,5}, FALSE))
What would be the output of this
Do you know that you can use arrays for 3rd parameter in VLOOKUP? When you do it, you will get values from all column numbers mentioned in the array. So we get Joyce’s salary, special allowance, travel allowance and bonus amounts.
When wrapped in SUMPRODUCT, this will just be the sum of all these numbers.
Related: Extracting values from multiple columns using VLOOKUP.
To get the value from 2nd column, we write =VLOOKUP(value to lookup, A1:Z1000, 2, false)
To get 3rd column value, we need to replace 2 with 3.
What if we can write 1 formula and drag it side-ways so that 2 becomes 3,4…24,25?
Enter the COLUMNS() formula. It can be used to generate running numbers. So, our formula becomes,
=VLOOKUP(value to lookup, $A$1:$Z$1000, COLUMNS($A$1:A$1)+1, false)
now, you can just drag the VLOOKUP formula sideways and it will get you all the 25 values 🙂
Apart from COLUMNS(), you can also use ROWS(), COLUMN(), ROW() or simply a set of 25 numbers typed in a range and using cell references in place of 2,3,…24,25.
You can use any of below formulas to do this:
SUMIFS
=SUMIFS(amounts, customerIDs, this customer, invoiceIDs, this invocie)
SUMPRODUCT
=SUMPRODUCT(amounts, (customerIDs=this customer), (invoiceIDs=this invoice))
INDEX & MATCH
(Array formula)
{=INDEX(amounts, MATCH(this customer & this invoice, (customerIDs)&(invoiceIDs), 0)) }

Excellent post again from awesome chandoo.org
This is one of the post to evident, without using macros we can create excellent charts using available excel options.
Slicer is one of the useful option in excel 2010 .. excited to see more options in excel 2013.

Nice one chandoo............... great work done.....
Cool article. Only downside was that I didn't see at first that I needed 2010. Guess I still have to wait awhile before getting to try this out myself.
I consider myself an Excel expert, but you constantly amaze me with posts like this. Fantastic calendar!
Good post, like this little trick!!
How to not show the value in the cell
format the cell to custom with the below

Could you add lists of holidays to be transferred to the calendar days?
Two lists would be needed: 1) for the holidays that stay fixed (eg, CHristmas), and 2) for the holidays that move around (eg, Thanksgiving).
Such lists would be prepared externally, and the program would transfer their information to the appropriate days.
Wow! This is something amazing. I am going to do some practicals with this and show a sales trend on this. As we have our sales plans weekly basis, this should impress by boss when put in dashboard. Cool.
And thanks1
Chandoo you have a knack of getting on to these great looking very creative ideas!
One thing with calendars I have seen before is not catering for able to enter notes or appointments or project milestones. But with this one it's easy enough to add the extra lines as you have done for the chart concept and link to this other type of info.
For 2003 we could replace slicers with a validation style dropdown couldn't we?
Chandoo, you are awesome;) i was using calender to show my reports, but i had made all months and then underneith date shows the value, man its really awesome . i am going to use this format for my reports.. only draw back for me is i am using 2007. hence no slicer.. may be have to modify with out slicer.
Why not use =weeknum() for the weeknum column?
Great tricks! I love trying to reproduce the charts myself to get the hang of 'em. This one was great.
My only issue is getting the VBA in the year object to refresh the data. I used the VBA provided at the link, and, I can see it in the Macros tab, but, when I click the spinner the data does not update. Any tips?
Thx!

^^Ignore this! NOT ENOUGH COFFEE YET.
I forgot about the "Assign Macro" option
:-s
Just started at chandoo - this is great!
I opted to use the formula =IF(F6>F5,G5,G5+1) for my weeknum - worked for me (I didn't get all the way through the example, since I'm running Excel 2007 - so don't know if that'll affect anything later in the example). I'm open to comments on this alternative approach.
Thanks for creating this website!
VC (Excel student).
Very cool - but now I'm even more excited for the new time controls for Excel 2013!
Great calendar...
I wonder whether we can make a school calendar (Class, subjects, teachers) using this calendar, assuming the weekly plan is duplicated across the year.
I would love to be a part of creating a class schedule...I'm attempting to help a friend (gratis) to do just that - can you point me in the right direction or provide a sample of sorts?

Hello Chandoo,
Great works! I learn a lot from this website. Here is the problem I met when I follow your tutorial: once I run and save this cool pivot calendar chart , the size of excel file will increase every time. Could you let me know how to figure it out? Thank you for your time in advance.
An excel chart-fan from China.
I already figured it out.
wow, love the calendar, i'm a newbie, found this site and it's amazing.
Got it mostly figured out, but could do with help with your named range 'tblchosen'
I can build the pivots, link the calendars together but can't see how to use index(tblchosen...) to pull through the productivity figures
appreciate any help
thanks
Great. Miss the Today button. Will try and figure a way to add this to the file.
I want to start the week on Monday, not Sunday (MTWTFSS). Re-arranging the calendar tab works however, any month where the 1st is a Sunday starts on the second and totally omits Sun 1. I have been tinkerign for a while, but can't seem to figure this out.
Changing F2 on the 'Calcs' tab to 2 so that the week starts on Monday works.
Cutting & pasting Sunday on the 'Pivot Calendar' tab and moving all cells up 1 row works.
However, using April 2013 for example, you lose the 1st off of the pivot calendar so that the month starts on 2 April. What should happen is the first row should only show Sun 1 April and then the next row starts Mon 2 April. Still can't fugure out where the problem lies.
"Further Enhancements:
Adjust week start to Monday: Likewise, you can modify your formulas to adjust weekstart to Monday or any other day you fancy."
I have tinkered with this previously with no success, does anyone know which formulas require tinkering, I have only succeeded in breaking this in an effort start a week on a Monday.

Completely off topic, but how do you create those animated pictures in your tutorials? It is not a movie (like the Youtube movie), so what software do you use to create such high quality "animated" pictires? Thanks
Jeroen
the animated pics are called Animated Gifs
they are made using Camtasia

This is fairly easy to do just using calendar formulas, which would be quicker, and doesn't need VBA? Am I missing something?

Great tip shared by you... howevr would appreciate if you could mention in your tricks about excel version. The example above would work only in excel 2010 and above I believe. Please help me if there is any way we can use the tip in excel 2007 as well..
Many Thanks,

Hi, I'm going to give this a shot, but one small question before I do. Can a linked cell be updated based on the date that is selected from the calendar? The calendar is really cool and this would make is especially good to use (and easy and fast).
Regards,
swissfish.
This post is awesome, and using your instructions, I was able to get this to work with a pivot table that pulls directly from a Project Server database. It was a bit complicated to get the day to sum correctly, but I managed to finagle it. I hope you don't mind if I link back to you when I post my instructions.
Thanks for giving me a starting point for this!

This is great, and pretty much everything I was looking for.
However, I already have a large spreadsheet, and I want to include your worksheets in it. I copied all the worksheets and the Module 1, but I can't get it to work. What else do I need to transfer / update please?
Hello there, is it possible to use this pivot to produce a calendar style chart, with returns multiple data per date, which on the calendar then, when clicked links to the data to provide more background information? What do you think? I'd love if I could pivot when i need. thanks, m
Hi, did you ever figure out how to do this? I would love to find a way...
This is amazing and will work well for my calendar project! My question is, how can I expand the calendar to fit a standard sheet of paper?
Wow - this is so creative. I'm taking the basic idea and building a reservation calendar.
Question: How do you get the month and year slicers on a different page than the pivot tables? I'd like to have my final calendar on a separate page from the pivot.

This is perfect...is there a way to add notes/tasks to the individual days?
Excel will not let me insert blank rows between lines in the pivot table. I am use Excel 2013 - is there a pivot table tools command that must be used?
I can create the pivot table calender with a year spinner & month slicer but I do not see how to display the the attendance information that I have in the original data table.
Thank you for the wonderful post and I am sorry for my lack of understanding...
Excellent!
Please show me how to add an alternative calendar to this calendar, Chinese or lunar calendar (and by lunar I don't mean phases of the moon), like what they still use in Asia
Thanks
Christopher

Hello my name is Maurice, excuse me for my further request, but believe me, without your help priprio not know how to solve this problem.
So: always using a chart positioned on an excel sheet I wanted to match each square (series) to a single cell, to create a perpetual calendar.
Now everything works fine; except that for a fact, and it is this: In the calendar as you well know some numbers may not be apparent until certain conditions, which I solved by writing this "= O code (AA5 = DATE ( $ H $ 1; MONTH ($ AD $ 12) +1; 1)) and the game and done.
Now I would like to achieve the same thing using the Chart; How can I do to make this happen! let me also just a practical example so that I can understand all the rest then I'll do; Thanks Greetings from A.Maurizio

Great info, thanks for sharing
Hi,
I love your calendar however I am modifying it for use in displaying employee performance metrics on a day by day basis.
I see where tblChosen and tblDates are named ranges however I cannot find them anywhere.
Are they assigned to specific cells because I cannot tell.
I see both of them in the Name Manager, which tells me what they refer to but does not give a value or cell location.
@Mike
With the Names in the Name Manager
Simply select the name
Then click in the Refers To: box at the Bottom
Excel will take you to where the Named Range is referring to

Hi, Chandoo
This Pivot Calendar is an excellent idea. I’ve done one for myself using your guidelines. I just need something I’m not being able to do. I need that when I open the file the default date is set to today’s date. I know how to do it with conditional formatting. But I think I’ll need some vba coding for this. Can you please help me with this. Thanks in advance
