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
The 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$7="Full List",Full-list-range,Partial-list-range)
That is all, you now have a data validation list that can change its source based on user preference.
Problem 2 : You would like to change a list’s values based on what is selected in another list
PS: Many thanks to Catherine for asking this question through email
You have a status tracking spreadsheet where each employee enters the status for each of the projects they are working on. They enter the status by first selecting the department and then selecting a project (from that department).
So how do you do this in Excel?
Solution: Use OFFSET and MATCH to determine which range to use
Remember the offset() and match() formulas we discussed in the last spreadcheats? Assuming the list of projects for each department is in a range B10:C22 with column B having the department name and column C having the project name and the list is sorted on column B, we can use offset() and match() combination along with countif (ahem!) to determine which range to use for project cell drop-down.
- For the department cell, we can use simple list validation with values as “Marketing, Ops, Sales, IT”
- For project cell, go to data validation (menu > data > validation) and specify a formula like this:
=OFFSET(C9,MATCH($B$6,$B$10:$B$22,0),0,COUNTIF(B10:B22,$B$6),1) - 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?

21 Responses to “Distinct count in Excel pivot tables”
The distinct count option works well but I have found that if I have a date field and want to group by year, month, etc. that option seems to be disabled. I need to do both, distinct count and group by year/month.
Example data; sales orders with item quantities with dates.
Challenge; sum the item quantities, count the distinct orders and group by month. How do I do this?
Perhaps that's not possible due to the grouping?
@Al... When you use data model based pivots, you cannot group values manually anymore. Why not use Excel 2016's default date grouping option? In this case we have just a few dates, so Excel is not grouping them, but if you have an year's worth of data, when you make the pivot with date in the row label area, Excel automatically groups them. If you have fewer dates or want to use your own grouping, just create a table with all dates, add columns with month, week, year etc. Then connect this table (these types of tables are usually called as calendar tables) to your data on date field as a relationship. Now you can create reports by month, quarter etc easily.
Is this the only way to do it in 2013? I find it rather cumbersome to have to create another data table listing dates with the another column for MONTH() and YEAR() to be able to summarise data for senior level...
I know people find adding calendar tables cumbersome, but it is a best practice and let's you add more layers of analysis quite easily. For example, adding analysis by weekday vs. weekend or by financial quarter or YTD calculations (you would need either Power Pivot DAX or some very carefully setup pivot table value field settings)
I had absolutely no idea this was possible. Very useful, nice work!
Doesn't work for 2010 version though (or at least not my works version)
Hi ,
The post has the following in it :
These instructions work only in Excel 2016, Office 365 and Excel 2013.
when i have 2 different Pivot tables, one without the enabled “Add this data to data model” option, and the other one with it enabled.. is there anyway i can link slicers between them?
if the answer is NO,, what to do ?
Quick note, the “Add this data to data model” option is not available for the Mac version.
perhaps outside scope of this article but I have found when I attempt to create a pivot table from an external data source (connection to a sql view) the "Add this data to data model" becomes greyed out. Anybody experienced and found a solution so I can start getting distinct count in my pivot tables?
Is there a way to still add a calculated field when using distinct count?
I found I can't change the date source after tick the " add this data to the data model", can you help to adv how to change the date source in such case?
Is there a way to update the source once you have added to the data model? I receive a new spreadsheet weekly and would like to update the connection so my tables pull from the new source.
Hi Crhis, I like how you have hulk (superhero) as your avatar. Do you know that there is a superhero in Excel too? It's Power Query. You can use it to solve your problem in a simple click. Here an intro if you need some guidance.
Powerful Introduction to Power Query
A big Thank you. It worked.
Hi, have survey data that I need to analyze but the challenge is that my key fields are showing horizontally. I tried to transpose the fields using Power Query, but unfortunately the new fields are returning same values on a pivot table despite using distinct values
How I can a do a pivot table with discount conts in some columns and then generate shor report filter pages. pls it drives crazy
Hi. Why grand total pivot of distinct count is 13? shouldn't it be 67?
Great Answer! Saved me lots of time!
Thank you!!!
Worked awesome! Thanks!!
Hi Chandoo,
I am using pivot tables for distinct count and now I need to update them with new set of data. But when I update the source data, all the columns and formatting of Pivot table disappears and I need to build it from Scratch.
Is there a possibility that I can update the source data with new rows added and also retain my pivot tables?
