Advanced Data Validation Techniques in Excel [spreadcheats]

Posted on November 25th, 2008 in Learn Excel - 108 comments

Data validation is a great way to keep your users informed about possible values in a cell and guide them to select something appropriate. As part of the spreadcheats series, in this post we will discuss 2 advanced data validation techniques that can help you when you are modeling a complex worksheet.

Problem 1: You have 2 lists of possible values and you want a way to switch between both

PS: Many thanks to Alex who proposed this idea and solution through e-mail.

You have a cell where user can enter any value from 2 lists. But you don’t want to overload the in-cell drop down list with tons of values, and rather prefer a simpler approach like this:


Solution: Use an IF() formula in validation criteria

validation-criteria-if-formulaThe solution is to use an if() formula to determine which one of the two ranges should be used to validate cell contents.

  • Select the cell where you want to have this type of validation
  • Go to menu > data > validation
  • In the criteria area, select “allow” as “list”
  • In the source area, specify a formula like this: =IF($B$7="Full List",Full-list-range,Partial-list-range)

That is all, you now have a data validation list that can change its source based on user preference.

Problem 2 : You would like to change a list’s values based on what is selected in another list

data-validation-change-listsPS: Many thanks to Catherine for asking this question through email

You have a status tracking spreadsheet where each employee enters the status for each of the projects they are working on. They enter the status by first selecting the department and then selecting a project (from that department).

So how do you do this in Excel?

Solution: Use OFFSET and MATCH to determine which range to use

Remember the offset() and match() formulas we discussed in the last spreadcheats?  Assuming the list of projects for each department is in a range B10:C22 with column B having the department name and column C having the project name and the list is sorted on column B, we can use offset() and match() combination along with countif (ahem!) to determine which range to use for project cell drop-down.

  • For the department cell, we can use simple list validation with values as “Marketing, Ops, Sales, IT”
  • For project cell, go to data validation (menu > data > validation) and specify a formula like this:
  • What is above formula doing? It is fetching a sub-range from the by finding where the first entry for the selected department is, returning x number of rows from that point, where x = no. of projects in that department.

That is all. You now have a list drop-down that changes values based on what is selected in an earlier cell.

Still having doubts?

  1. Jorge Camoes says:

    Let me add that usually you should have those lists in a "control" or "support" sheet, creating a named range for each list. Then you could enter: If($B$7="Full List", range1, range2). Just a bit cleaner.

  2. Chandoo says:

    @Jorge: You are right... using a control sheet is always advisable.

    • AFP says:


      OFFSET(reference, rows, cols, [height], [width])

      Hello everybody,

      I am trying to use the OFFSET proposed formula =OFFSET(C9,MATCH($B$6,$B$10:$B$22,0),0,COUNTIF(B10:B22,$B$6),1) but doing "reference" from a another sheet in the same woorkbook.

      Can you confirm that the OFFSET accept a "reference" from another sheet in the same workbook, e.g. sheet2!C9...

      Thank you in advance for your feedback.

      • Hui... says:

        Yes, That can be done and your format is correct

        Just remember that if there are multiple values of the cell B6 in the range B10:B22 that you will get a #Value! error
        That occurs as you are trying to return a Range which will be the No of occurrences of B6 in the Range B10:B22 long
        If you want just the cell at the offset, use:

        If you want to sum up that many cells use

        • Animesh says:

          any suggestion on-
          (1)how to make this data range dynamic
          (2)Data Validation will be on a separate sheet
          (3)Whatever data updated on the data range, the same will be automatically update in Data Validation list in separate sheet.

      • George says:

        yes is does

  3. Ketan says:

    @ Jorge & Chandoo == Thanx for nice idea. Without naming the range, control/list from other sheet does not work.

  4. Ketan says:

    @ Jorge & Chandoo == Ref. Problem#2
    If you make databse in following order of Area, it won't work :

    i.e. all the similar areas are to have one after other OR need to sort on area.

    Your comment pls !

    • Greg says:

      Yes I notice that if col A is not sorted and select project dropdown list values will be incorrect for any unsorted selection from Col A. Is there any way to sort this using formula first. I am trying to stay away from using vba

  5. Lincoln says:


    That's why it says in the solution that "the list is sorted on column B".

  6. Chandoo says:

    @Lincoln: thanks...

    @Ketan: you are right The list needs to be sorted as I have noted in the article.

    There are some solutions involving array formulas (shudder) etc. to overcome this, but I always try to keep these things simple so that anyone can understand and use. As such I am no good at array formulas myself and don't venture in to them unless they are the only option.

  7. Cheryl says:

    Since we are on the topic of named ranges (well sort of) can someone tell me an easy way to rename a named range? I have a report where it would be really helpful to use a named range in my vlookup but the range varies month to month..
    And since it's Thanksgiving, I wanted to say thanks to you Chandoo because people think I spend hours & hours researching how to do things when really most of my information comes from right here!! 🙂

  8. azmat says:

    I have a question....may b m asking for too much....can it work like we have on web pages...i wud illustrate it wid an example as to what actualy am lukin for....

    suppose when we select deptt "Ops" then it should remove the value currently present in project value instantly.......(if it's not of "Ops" deptt)

  9. Chandoo says:

    @Cheryl... thank you. did you try using indirect or offset functions in the named range definition. That way even though the names stays same, you can change the range it refers to by simply changing value in a control cell. Let me know if you have trouble in doing this. I can elaborate on this.

    @Azmat: hmm.. resetting value on previous selection... I guess you can use VBA to get this effect. But you wouldnt probably want to use vba. I dont know other ways around this. Does any one know how to reset a data validation enabled field when some other cell changes?

  10. Cheryl says:

    I have not, but I know you did have a posting about those recently. I will check that out! Thank you.

  11. Karthik says:

    Have a simpler version of this solutions.
    1. Define a name range with name as "Department" and list containing “Marketing, Ops, Sales, IT”
    For Ex: In D1 put the title as Department, D2 as Marketing, D3 as Ops and so on
    2. For each of the projects define a named range with the department names.
    E1 will have the title Manufacturing, E2 has project 1,project2 ...
    3. In Cell A1 use data >> Validation >> source = Department
    4. In Cell B2 just use data >> Validation >> source =INDIRECT(A1)

  12. Asif says:

    Hey in all the above examples the 'list' is in the same Excel file. What will I do if my 'list' is another Excel file?

    • Taha says:

      Hey there Asif,
      Name your list first and then in validation box type the name of your list. Let's assume you name your list as LIST. So in validation box type as =LIST and it will work. Please reply with your reslut.

  14. Darwin de Leon says:

    Why is it that if you extend the Range ($B$10:$B$22) to for example ($B$10:$B$33) it gives you wrong output?

  15. Chandoo says:

    @Darwin .. Are you sure you have edited the range in all places?

  16. Darwin de Leon says:

    I used your sample Excel file to test the data and extend the rows up to B33, then in Data Validation>Source I try to change the formula to this: =OFFSET(C9,MATCH($B$6,$B$10:$B$33,0),0,COUNTIF(B10:B33,$B$6),1)

    If I select Marketing, the resulting list includes Projects under Ops Area.

  17. Darwin de Leon says:

    I sent you an email with your sample data and additional rows in your gmail.

  18. Chandoo says:

    @Darwin... Did you sort the list by department name? It seems to work fine for me.

  19. Darwin de Leon says:

    Got it! I should have paid attention to the comments here. Thanks!

  20. Adnan Rafiq says:

    Can anybody tell me about calender of date option in data validation, when I wish to put any date then calender should appear on screen.

    Your reply will be highly appreciated.

    thanks and and regards,

  21. Chandoo says:

    @Adnan... I think you have to use a bit of VBA to show calendar control to let user enter valid dates.

  22. Amien says:

    I've got a few columns of data where the next column need to refer to the previous as data vaildation eg. District, Area, Area Manager, Project No. etc. if i choose a district (North) it brings up only the Areas for North but how can I go beyond that so that in a next cell I can select the Area Manager for that Area & the Project numbers for that Area

  23. Venkatesh says:

    Dear Chandoo,

    Am a Silent reader of your posts and this blog..Its quite interesting and very useful for me..
    In the above post, using Indirect(Cell reference) also works very well...The referenced cell may contain any one of the Name..


  24. Hui... says:

    There are several examples and free pop up calendars
    a quick search of Google will find references to both

  25. Venkatesh says:

    Amein, the same can be done with the use of Name Manager and INDIRECT function...

  26. Jon says:

    This is excellent - really helped me out. However, still a little stuck I'm afraid. I have 7 lists in total, each needs to feed off the preceeding list. Can you give me some guidance on what I need to have in the data validation cells from list 3 - 7 so it includes all of the previous entries?

    Additionally, there is some overlap in each list (i.e. I have one list titled Region, where Global is seen in more than one of the preceeding categories). Right now, when I click the drop down list I get multiple Global's rather than just one.

    Any thoughts? I've been working on this for ages now so any help you can give would be great!

  27. Francis says:


    What if I have problem 1 in problem 2 above?

    To explain, If my list under marketing is too big and I only want to see only the items that are frequently used instead of all available items, how should I amend my formula?

    Help please!!!

  28. john says:

    The data has to be in the same worksheet i believe? usually a separate worksheet is used for reference. could you clarify how do you go about it? It doesnt work if you reference the data from a different sheet. the control page or something mentioned is not clear to me.

  29. ahmet says:

    Hi Chandoo,

    I am not too sure if i can use data validation with the problem that i have.

    I have a data enry of around 5000 rows in 1 sheet and i want to be able to select a person randomly after applying auto filters.

    i am not sure if this is possible.

    say for example, i want to select a name randomly which is in coumn D after filtering using other columns which shows me who is attended a specific course, meeting etc.

    your help would be much appreciated.

    Please help in creating Data Validation which accepts only text.

    Please Note: It should not accept text and number combination.


  31. Ananthanarayanan says:

    I have created a file with data validation. In a column there are over 75 entries in a drop down data. One has to scroll through the list to select an entry.
    Is there a way by which just by entering the 1st letter or the 1st two letter, the drop down list shownall the data with these starting letters so that the selection becomes easier.
    My thanks in advance for this guidance.

  32. Hui... says:

    Excel doesn't have an Auto Complete facility in Data Validation.
    But with a bit of careful planning you can achieve the same result.
    Read how here:

  33. jagmohan says:


    If the lists are as follows what is the expected list in first dropdown?

    B C
    a aa
    a ab
    a ac
    a ad
    b ba
    b bb
    c ca
    c cb
    c cc
    c cd
    c ce
    d da
    d db
    d dc

    What I get in first dropdown is {a, a, a, a, b, b, c, c, c, c, c, d, d, d}. How to reduce it down to only {a, b, c, d}



  34. Hui... says:

    Have a look at some techniques here
    or use an Advanced Filter
    All of these techniques can be automated if required.

  35. jagmohan says:

    Hi Hui,

    Thanks. I tried to use the Pivot table technique and it worked. Further question on the same.

    Now I add few items in column H and column I (sorted again) - as follows

    Excel Information
    The lists are in Column H and I starting from row 4. F9 contains the first drop down. G9 contains the second dropdown. Pivot is located in Column M starting from row 13.

    H I
    a aa
    a ab
    a ac
    a ad
    b ba
    b bb
    c ca
    c cb
    c cc
    c cd
    c ce
    d da <- New item
    d db <- New item
    d dc <- New item

    Now is it that I need to delete the pivot table, create a new one and then use it? Or is there any technique by which I can dynamically grow the pivot table?

    Ofcourse I changed the formula in G9 to following
    offset(I4, match($F$9, offset($H:$H,0,0,counta($H:$H)-1,1),0), 0, countif(offset($H:$H,0,0,counta($H:$H)-1,1),$F$9), 1)

  36. Hui... says:


    If the pivot table is based on a Dynamic Range, then refreshing the pivot table will add the extra items.

  37. jagmohan says:

    Now how do I check that?

  38. Hui... says:

    Dynamic Ranges expand/defalte as the data in the range increases or is deleted
    They are added using Named Formula
    Once you setup a Named Formula for your range, change the pivot table to be based on that range
    As you add or remove data and update the pivot table it will adjust for the new data scenario

    I want to be able to use data validation where the restricted input would be either a number greater than 0 or the text "na". I tried using an OR statement, but it didn't work. Not sure if I just had bad syntax or if I can't do it that way. Any help would be appreciated.

    I wanted to create dependent lists. For example:

    TaskB BAU Y403

    TaskB BAU Y412

    I need to find out what formula should I put in my data validation in Col B so that when TaskA is selected, I will only see "BAU" and "PRJ" in the dropdown list and "PRJ" should come only once. When TaskB is selected, I will only see "BAU" once. Presently with your solution I can only get to the stage where BAU will appear 3 times, if TaskB is selected.

    Thank you so much in advance for your help.

    Hi C
    sometimes the forum looks like a wishing list 😉
    why not to add more to it...
    Change list values based on what is selected in another list?

    could you elaborate more in the case of a 3rd or a 4th list how the offset should look like, e.g..:
    List 1

    XL Men
    L Men
    L Women
    M Women

    so, ig I pick Men from one data list I will get from list 2 Blue and for list3 XL Men & L Men,
    what will be the best way to do it?

    Chandoo.. This is an amazing trick.. thanks a ton 🙂

  54. Ollie Wood says:

    I am using the second formula using offset and match and it works fine when the list is sorted. My list is sorted but there may be instances when it is not. This formula doesn't then return the correct values. Do you have any ideas how to get around this?

  55. Kristian says:

    In the second problem, how do one allow for the user to enter data freely in the project list?
    E.g. in my sheet the user can first choose between the areas "marketing", "sales", "ops" or "others". If the user selects one of the first three he will get a new list to choose from in the "select project cell", but if the user selects "other" he should be able to type in whatever he wants in that cell.

  56. Tom says:

    When dealing with PROBLEM 1 i have another Problem using Data Validation. The Solution works perfekt, but activating "Circle Invalid Data" leads to the following problem:

    In SITUATION1, when selecting a value of the "Partial-list-range" the data is not recognized as invalid data. But selecting "FullList" (SITUATION2) and then a value of the "Full-list-range" the cell is circled and marked with a Data Validation Error. Saying "Restriction: Value must match one of the listed items".

    I have googled my a** of to find anything about this problem or a workaround or sth., but without succes. I was not able to teach excel that a value of either the one or the other list is valid.
    Can anybody help me with this issue?

    Hello everyone,
    Is it possible to limit the data range depending upon value selected in drop down list.

    Suppose i have a drop down list (say in cell M1)which has 5 options, namely Refrigerator, TV, Mixer, Micro oven, Speaker.
    Now i want to limit the data entered in cell X20 depending upon the option selected.
    For example:
    For TV maximum value allowed to be entered in cell X20 = 1000$, For refrigerator 800 $ and so on....
    Is it possible to do in excel 2010? If it is possible, tell me how to do it.
    Thanks & Regards

  58. Abhinandan says:

    Thanks a ton sir.
    It's really working.
    But there is a problem. I can still Copy paste the data above the maximum limit. Let say for TV maximum limit is 800. In some other cell (which is not Protected) i wrote 1000. Now i copied that 1000 and paste it into the validated cell. And it is showing 1000 as input.
    Can you tell me how to protect it from copy paste option?

    Thanks & Regards

    I have used this validation:
    I want to copy this into about 300 more cells, but I need the values for C11 to change to each subsequent cell. (C12, C13, etc)
    I have tried making Fields instead of point to a specific cell, but this brings me errors. Is there a fast way to copy the "equation" while changing cells to fit reference cells per row? Right now, I am manually changing all of them. Way too much time for what I am doing.

    • Hui... says:

      Remove the $ from the C11

      The $ locks that component of the cell reference and hence it doesn't change as you copy the formula

    I would like to create a ONE to MANY drop down list.

    E.g. I have a sheet with the first drop down as COUNTRY, after selecting country I would like multiple other lists to be dependant on this first selection, so BLOCK or CONTRACT lists should refer to the selection in COUNTRY and then the options reflect the chosen COUNTRY, is this possible?

    I can create 1 dependant list using the INDIRECT formula without problem but I cannot get any additional lists created that are dependent on the first selection due to not being able to define the names in the same way, i.e. select UK as country then the next list is defined by UK but I cannot create a third due to not being able to name another list as 'UK'.

    Please can you help me out with this. (Hopefully what I have written makes sense and is clear enough...)

    I am trying your worksheet example, applying Table Nomenclature.

    I copied your validation cels (B6...C7) to B30:C31; the data table from B9:C22 to B34:C47 =(Table1, fields: [Area] and

    The offset function is =OFFSET($C$34;MATCH($B$31;Table1[[Area]:[Area]];0);0;COUNTIF(Table1[Area];$B$31);1)

    The formula works out fine when reviewed (in Edit Mode, a "F9" over the entire formula). But when the same is pasted to the data validation, excel compains there is a mistake in the writing of the formula and does not allow it.

    May I suggest that in your example worksheets, you also provide examples using "Table Nomenclature.."

    Can you help..!!

    Many thanks... and kind regards

    I am using offset+match+countif in my validation list and I am able to get the correct range of list.

    However, even tough I have checked the error alert box in the data validation, there is no error message prompt out if I manually input wrong description. I wish there is error message prompt out if I input invalid data, does anyone have any suggestion?

    I have a spreadsheet that is updated very frequently. At any point in time I will need to print out data that has been collected today (=Today() ). Once printed, only fresh data with Today's date will be printed and not any previous data.

    Any help would be appreciated.

    I was trying to do Problem 2 - "You would like to change a list’s values based on what is selected in another list"

    My problem is I can't create the drop down in the second column (the projects, in column D). The formula only works if I enter it in the cell, but then I get the full list, not a drop down.

    Here is what I mean - go to Test tab

    Thank you for your help,

    Ans = 0
    Function da(basic)
    If MTH >= 1 Then
    da = basic * 0.05
    ElseIf MTH >= 5 Then
    da = basic * 0.1
    da = 0
    End If
    da = Application.Round(da, 2)

    I have a spreadsheet that works on a value entered in one box then generates a unit number in another so e.g. No of units = 10 it gives you 10 cells underneath labels U1-U10 under these are drop downs that give you option of small - large per unit of which then the selection returns a value of pages 30-90 to allow us to cost the units, The problem I have is that if you select 10 units max select the small - large drop downs it works fine but if you then change the 10 to 5 units the units headers disappear but the drop down list below remains and stays stuck on the previous selection so still brings in a page number and therefore a calculation of costs. Is there a way to refresh and remove the drop down when the header above is not there. The drop down is dependent on the unit header been above.

    I am using a list box (form controls) which is for listing the months. Is there any way I can make the list dynamic ie., for July, the list will show Apr. to Jul. Next month, it will Apr. to Aug. so on.
    Alternately, pl. suggest the way forward in Data validation.

    Dear sir,
    I have two queries.
    1. I have applied data validation rule to a range of cells to accept only decimals between 0 to 30. It works well, but it accepts other values when copied and pasted to that range. So, how do I restrict copy-paste on those cells?
    2. i stored marks of students out of 50. Data validation check is applied to restrict user from entering wrong values too. but now it does not allow me to place "ABSENT" to some cells. So, How to add multiple checks to data validation?

    Please reply at your earliest...
    Thanks in advance.

    I have 2 validation drop down list. Second validaion drop down list is based on first one.

    Validation is working fine for me. My question is if I change select any value from first drop down, in second i get the correct list, but I get selected value from previously selected option.
    Example: If I have firstname and lastnames in first drop down list, if i select my name "Gagan" from first list then i get "Chawla" from second list which is correct, but if I change first one to any other name, I see "Chawla" already in cell how to change this? So that i someone forgets to change dependent list, it should be blank?

    Hello gurus, I have struggled to avoid using OFFSET function in the drop down list. I have made this formula to determine the range to use, but the formula is not being accepted in data validation. Please help. Thanks: =INDEX($C$10:$C$22,MATCH(B6,B10:B22,0)):INDEX(C10:C22,MATCH(2,1/(B10:B22=B6)))

    First of all I love your emails and all of your tips. When using a formula as the source for a list in Data Validation and it is longer that the text box, is there any easy to edit any portions that are beyond the edge of the text box. I can place the cursor at the far right and then press the right arrow key but it always adds a cell reference that I then have to take out. I can they make my changes. Is there a better way?
