Imagine carefully creating a workbook with several calculations and formulas only see errors. What to do when you get an Excel formula error? Of course, you can shake your head and ask, “Why, why would you do that?”, but that will not help.
So in this article let’s learn how to fix Excel formula error. Those annoying #SOMETHING!s that you see when your excel formulas have something wrong with them.
Excel Formula Error Checklist
Use this checklist to quickly understand common formula errors, what they mean, when you would see them and how to fix them. Read on to know more about the errors.
| Error | What it means? | Most common reason | How to fix it? |
|---|---|---|---|
| #N/A | Not Applicable | When VLLOKUP can't find what you want | Make sure your list has the value you are looking for. Use IFERROR or IFNA to fix |
| #DIV/0! | Divide by Zero | Denominator is zero | Use IF formula to safe divide |
| #NAME? | Could not find the name | Spelling mistake / typo | Double check your formula and fix the error |
| ######### | Could not display or format | Cell too small | Adjust column width |
| #VALUE! | Invalid value | Converting non-dates or numbers | Make sure your dates are correctly formatted |
| #REF! | Reference missing | When you delete a row / column / cell | Check cell dependancies before deleting |
| #NUM! | Invalid number | Number too high or too low | Check your calculation |
| #NULL! | Missing or null value | Reference points to nothing | See if your references are right |
#N/A Formula Error
This is one of the most frequent excel formula error you see while using vlookup formula. The N/A error is shown when some data is missing, or inappropriate arguments are passed to the lookup functions (vlookup, hlookup etc.) of if the list is not sorted and you are trying to lookup using sort option. You can also generate a #N/A error by writing =NA() in a cell.
How to fix #N/A error?
Make sure you wrap the lookup functions with some error handling mechanism. For eg. if you are not sure the value you are looking is available, you can write something like =IFERROR(VLOOKUP(…), “Value not found”). This will print “value not found” whenever the vlookup returns any error (including #N/A)

#DIV/0! Formula Error
This is the easiest of all. When you divide something with 0, you see this error. For eg. a cell with the formula =23/0 would return in this error.
How to fix #DIV/0 error?
Simple, use IF formula to safe divide, like this:
=IF(A2=0, “”, A1/A2)
#NAME? Formula Error
The most common reason why you see this error is because you misspelled a formula or table or named range. For eg. if you write =summa(a1:a10) in a cell, it would return #NAME? error. There are few other reasons why this can happen. If you forget to close a text in double quotes or omit the range operator :. All these examples should return #NAME? error. =sum(range1, UNDEFIED_RANGE_NAME), =sum(a1a10)
How to fix #NAME? Error?
- Make sure you have mentioned the correct formula name. Use auto-complete when typing formulas. This way, when you type formulas or use names / structural references, you will not make any mistakes.
- Make sure you have defined all the tables and named ranges you are using in the formula.
- Make sure any user defined functions you are using are properly installed.
- Double check the ranges and string parameters in your formulas.
###### Error
You see a cell full of # symbols when the contents cannot fit in the cell. For eg. a long number like 2339432094394 entered in a small cell will show ####s. Also, you see the ###### when you format negative numbers as dates.
How to fix the ###### error?
Simple, adjust the column width. And if the error is due to negative dates, make them positive.
#VALUE! Excel Formula Error
Value error is shown when you use text parameters to a function that accepts numbers. For eg. the formula =SUM(“ab”,”cd”) returns #VALUE! error.
How to fix the #VALUE! error?
Make sure your formula parameters have correct data types. If you are using functions that work on numbers (like sum, sumproduct etc.) then the parameters should be numbers.
#REF! Formula Error
This is one of the most common error messages you see when you fiddle with a worksheet full of formulas. You get #REF! Excel formula error when one of the formula parameters is pointing to an invalid range. This can happen because you deleted the cells. For eg. try to write a sum forumla like =SUM(A1:A10, B1:B10, C1:C10) and then delete the column C. Immediately the sum formula returns #REF! error.
How to fix the #REF! error?
First press ctrl+Z and undo the actions you have performed. And then rethink if there is a better way to write the formula or perform the action (deleting cells).
#NUM! Excel Error
This is number error that you see when your formula returns a value bigger than what excel can represent. You will also get this error if you are using iterative functions like IRR and the function cannot find any result. For eg. the formula =4389^7E+37 returns a #NUM! error.
How to fix #NUM! error?
Simple, make your numbers smaller or provide right starting values to your iterative formulas.
#NULL! Formula Error
This is rare error. When you use incorrect range operators often you get this error. For eg. the formula =SUM(D30:D32 C31:C33) returns a #NULL! error because there is no overlap between range 1 and range2.
How to fix the #NULL! error?
Make sure you have mentioned the ranges properly.
Formula not working – showing as text?
If you don’t see any error, but instead of seeing the result, all you see is your formula (like below), then check out Formulas not working page for information how to fix the problem.

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

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!

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).

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.
[…] http://chandoo.org/wp/2012/09/12/interactive-pivot-calendar/ […]
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
