Excel formula error checklist and how to fix excel errorsImagine 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.

What to do when you have an Excel error like #NA or #REF

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.

ErrorWhat it means?Most common reasonHow to fix it?
#N/ANot ApplicableWhen VLLOKUP can't find what you wantMake sure your list has the value you are looking for. Use IFERROR or IFNA to fix
#DIV/0!Divide by ZeroDenominator is zeroUse IF formula to safe divide
#NAME?Could not find the nameSpelling mistake / typoDouble check your formula and fix the error
#########Could not display or formatCell too smallAdjust column width
#VALUE!Invalid valueConverting non-dates or numbersMake sure your dates are correctly formatted
#REF!Reference missingWhen you delete a row / column / cellCheck cell dependancies before deleting
#NUM!Invalid numberNumber too high or too lowCheck your calculation
#NULL!Missing or null valueReference points to nothingSee 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.

    Hi Chandoo,

    your recent postings include only Excel 2007 templates. Unfortunately the company I work at still runs Excel 2003. Is it possible to get your awesome files in other excel version as well?

    Thanks so much for your great excel stuff!

  2. Stelios Tserkezis says:

    Is it possible to do this for shifts with hours instead of days? To organise a three shift day?

    Thanks in advance,

    Stelios

  3. MASTHAN says:

    In my organization there are 45 employees i need split then into three shifts ex:A shift:14,B shift:14,C shift:14 and week off:3 kindly help me on this.

  4. Hui... says:

    @Masthan

    You need to understand what rules your company has for the various shifts / roster combinations

  5. Georges Lacombe says:

    Chandoo, I once did a shift control spreadsheet for my team. I put one person in each line, the columns were the days. I put a shift code in each cell indicating in which shift that person should work, or if the person were out that day. I have two codes for being out. One is for vacations and one is to compensate days worked in weekends. This way I was able to count how many persons I have in each shift, how many were on vacations and how many were out compensating (that's the term we use here) weekend worked hours.
    Later I included the possibility of a person be in two lines one for normal hours other for overtime. This is mainly used for planning purposes. If you would like I can send you an example. The only problem of this spreadsheet is that we don't have a person view, only this consolidated view.

    • Chuck Vaughan says:

      Hi George, I would like to have a copy of your spreadsheet if you can share it.
       
      Thanks in advance, Chuck   

  6. Idan says:

    Hi Chandoo,

    Where is the code located ? is it VBA ? If so , how do you hide it ? Or it is .NET ?

    Thx

  7. Hui... says:

    @Idan
    .
    No VBA or code, it is all done with Mirrors.
    Only Joking,
    .
    But there is no VBA or code,
    It is all done with Named Formulas and Lookups.
    Have alook at the cells in the calander area and Named Formulas in the Formulas, Name Manager Tab.

  8. Anand Sant says:

    How can i calculate between two or more different workbooks? Please, reply me as early as possible.

    • Hui... says:

      @Anand
      Open the workbooks you want to link to
      Start a formula = and click and change between workbooks as required.
      You can use the View, Switch window menu to change workbooks mid formula

      The format for using workbooks is
      =[Workbook.xlsm]Sheet1!$A$1
      or
      =SUM('[Book2.xls]Sheet1'!$A$1:$D$10)
      etc

Thank you in advance.

  15. Veronica Burggren says:

    I've been trying to copy and/or recreate this to use in a workbook I'm doing for the transportation department I'm working for. I need to have the calendar on the first sheet in my document (it has graph's from data on another sheet). I'm trying to use it to track (with the conditional formatting) accidents and injuries. I've redone the conditional formatting to do 4 different accident types (no injury, near miss, OSHA recordable injury and work loss injury), but when I enter the formula's you have in the calendar portion where it says "DateOfFirst-FirstWeekDay" I can't figure out how you did that. Are you able to help?

  16. Pipin Fantom says:

    I would like to use Excel to solve the following problem for a community work. I want to create a Driver schedule for a given month from a pool of volunteers for a community service. Each of these volunteers can drive only on specific days in a week. I would like to populate the driving schedule for each weekday with primary, secondary and tertiary drivers in a random fashion so that I do not overburden one person. I would greatly any help you can provide.
