Extracting Unique, Duplicate and Missing Items using Formulas [spreadcheats]

Often I wish Microsoft had spent the effort and time on a data genie (and a set of powerful formulas) that can automate common data cleanup tasks like extracting duplicates, makings lists unique, find missing items, remove spaces etc. Alas, instead they have provided features like clippy which are intrusive to say the least.

So as part of our second installment of spreadcheats we will learn how to tackle few of the most common data processing tasks:

Getting Unique Items from a List of Cells

There are 3 simple ways to do this:

  1. Using Advanced Data Filter
  2. Using countif() and auto filter
  3. Using formulas as described here

Assuming you have data as shown in the picture aside (and wishing you will have customers like those):

  • First add a column to the left of the list. Here we will use formulas to fill numbers based on the uniqueness of the cell next to it.
  • Essentially our formula should generate numbers in increasing order as long as the corresponding item is unique and not increase the number otherwise.
  • So the formula for order column can be like this: =IF(COUNTIF(list-upto-that-point, current element)=1,previous-order+1, previous-order)
    See the example below:

    remember, the first cell order is 1.
  • See how we are using both absolute and relative references to fetch the counts.
  • Now add another column to the right of the list, here we will fetch unique items.
  • We will use vlookup() to fetch each of the 12 unique items. The formula goes like this:
    =VLOOKUP(running number,$B$4:$C$22,2,FALSE)
    You can wrap the vlookup() with if() formula to avoid seeing #value errors.

That is all. Using this method you can extract unique items froma list.

Eliminating Doubles from a List

There are 2 ways in which you can find and remove duplicates(doubles) in excel lists with ease:

  1. Using countif() and then auto-filter
  2. Using formulas

The process for finding duplicates using formulas is same as that of finding unique items.

Instead of writing COUNTIF(list-upto-that-point, current element)=1, we now write COUNTIF(list-upto-that-point, current element)=2. Also the first element’s count should be changed to zero.

Once done the list should look like what you see on the side.

Finding Missing Items by comparing one list with another:

Even though this might seem like a different challenge, it is infact same as the above techniques. You need to use countif() to compare first list’s elements with second list. How? that is your home work.

    Hi -
    This is a really great article because it's a simple and common thing you'd want to do with a pivot table but not at all obvious how to do it! So - muchas gracias to Chandoo and Yogesh!
    One thing - I couldn't get past the group error in the sample file. I would click on ungroup but it didn't seem to have any effect. I'd appreciate it if anybody has any pointers here.

    Hi Chandoo

    I am also having the group error. Can't seem to ungroup? Appreciate if you explain further on the steps required in order to get to calculated items.

    Many thanks and keep up the great work.

    Cheers

    Hi Chandoo,

    I'm struggling resolving the problem depicted below:
    I have a set of data, with (among others) a "Region" field (can be APJ, EMEA, or AMS), and a "Country" field.
    Unfortunately, I need to group data by the following 4 Regions: APeJ, Japan, EMEA and AMS.

    I first tried to make a pivot with Region and Country in the rows (or columns), and then group Country data as per the above.
    Alas, as soon as I have a new Country that appear in my data set, my groupings are broken, and I have to redo the job of ungrouping, grouping etc.

    I thought I could try to use calculated item, by adding first a new column to my dataset concatenating Region_Country, and create an "APeJ" calculated item that would sum all the "APJ_*" and substract the "APJ_Japan", but again, no clue, as I can't find a way to use any wild card in those formulas.

    Given that I already found extremely helpful tips and tricks in your site that helped me manage that bunch of data, I'm pretty sure you'll have a bright idea on how I can solve that one!

    Thanks in advance for your lights!

      Hi Catherine...

      In such cases, I advice using an additional column in the data itself. You can set-up a grouping table else where with country in first column, region in second column. And then in the data, you can add an extra column and use VLOOKUP to fetch the region based on the country.

      Then feed this entire data (with extra column) to pivot table and use the extra column to group the data.

        Hi Chandoo,

        Thank you for your prompt answer.
        I finally came to the same conclusion - after a rest 🙂 . I was probably too tired Friday evening (it was rather late), having spent hours in manipulating all my surveys data so as to pull rolling averages, make nice graphs and so on, and was trying to find a complex solution when there was a simple one.

        Thanks again,
        Catherine

    Hey,

    Great post!

    I for example have different database structure with the following fields :

    Date, Expense, Income, Sum (Income - Expense), Category (Sales, Cost of Goods and etc).

    Creating a P&L report for the whole year works great. Including gross margin % and etc.

    Though, creating P&L report by QTR/Month is becoming impossible since i get the following error : “This PivotTable report field is grouped. You cannot add calculated item to grouped filed.”

    Is there a solution for this kind of problem?
     

  10. klumsyboy says:

    Like Adam and Juanito, I also cannot ungroup.

    Would appreciate it if you can add a few more lines and a screenshot or two on where to put the mouse cursor to ungroup. 

  11. klumsyboy says:

    Hi,  I have figured out the ungrouping problem. One of the earlier steps was to group by month, if you pull the month back down to the column then right click and then select ungroup, then pull the month back up so you end up with just data source and budget/actual as the headings, then you can continue on.

  12. Kent Lau says:

    To solve the ungroup problem, my method is:
    Copy the "data" sheet to a whole new Excel workbook
    and directly work on Part 6.

    And since it is a fresh copy, Excel don't show me the "can't ungroup" problem. Hope this help.

    Thank you Yogesh for this wonderful tutorial.

    Just when i thought pivots were awesome i learn about inserting the calculated fields and that makes them more awesome. chandoo where have you been all my life.

  14. barrierone says:

    Hello - your P&L pivot version has really impressed my boss and would like to use it. I have applied it for a actual vs budget vs forecast model I have created. One problem. In your variance above the operating profit percent % variance shows 33.8% but I want it to show (0.01) point or the true diff from prior budget.

    I know I can add calculation to the side but boss would like to see it in pivot table.

    Please help
    Thanks

  15. barrierone says:

    I have a further query which may solve my above dilemma. Is it possible to add a column that calculates percent increase. So in the example above a new column would be added to show variance %.

    Any help would be appreciated.

    Thanks
