Recently, we discussed about the case of unwieldy data and how we lookup what we want using formulas like SUMIFS. Today, let us learn few more ways to solve the same problem.
First, a re-cap of the problem:
Here is a data-set:

The problem – build a lookup formula
And the problem. Oh, simple. Write a lookup formula to find how many customer walk-ins we have on any given day.
In the previous article, we discussed how to use SUMIFS to solve this problem. There were several amazing & awesome solutions shared by our readers in the comments section too.
Suitable structure spawns simple solutions
Poorly structured is the 2nd biggest problem of analysts. The first one is not enough coffee. That is why there is a dictum in the data analytics world.
Structure is everything
So, we can easily solve our lookup problem, if our data were to magically re-arranged in 2 column fashion – Data & Value.

This transformation can be done in 2 ways:
Option #1: Transforming Data – Using Formulas
We can use data fetching formulas like OFFSET or INDEX to re-arrange data in 2 columns.
Assuming,
- Our 2D data is in a named range data,
- There are running numbers starting with 0 in the cell J5
We can use below formula to fetch first column:
=IFERROR(INDEX(data,2*(INT(J5/7))+1,MOD(J5,7)+1),"")
for the second column, below formula works:
=IFERROR(INDEX(data,2*(INT(J5/7)+1),MOD(J5,7)+1),"")
How does this formula work?
I will explain the formula for first column. Deciphering 2nd column formula is your homework.
Here is the formula again: =IFERROR(INDEX(data,2*(INT(J5/7))+1,MOD(J5,7)+1),"")
Before understanding the formula, let’s take a minute to examine the structure of our raw data.
- Odd rows contain dates
- Even rows contain values
- There are 7 columns in total
- So to get the first date, we need to go to row 1 (first odd number), column 1
- To get the first value, we need to go to row 2 (first even number), column 1
- But to get 8th date, we need to go to row 3(2nd odd number), column 1
- So on
Let’s go from inside out.
2*(INT(J5/7))+1portion: This gives row number (ie odd number). J5 refers to running number and its value is 0. So we get 2*(INT(0/7))+1 = 1- This will be 3 when J5 becomes J12 (ie 8th date)
MOD(J5,7)+1portion: This gives column number. It will result in values 1 thru 7 in a cyclical fashion. Thanks to MOD.INDEX(data, ..., ...)portion: Now that we have both row & column numbers, INDEX formula kicks in and gets the corresponding date.IFERROR(INDEX(...),"")portion: This is to help in case we ran out of all dates & values in our INDEX formula. Read about IFERROR here.
Once you have the formulas for first date & value, simply drag them to get rest of the values.
Option #2: Transforming data – Using VBA
VBA Macros are perfect for scenarios like this. Usually transformation is something you need to do every-time you import data from external systems. So simply write a macro that can do this automatically.
Assuming our data is in the range data and the first cell of our extraction range is startHere, you can use below macro:
Sub rearrangeData()
'takes the values in DATA named range and rearranges them
'from the named cell startHere
Dim cell As Range, i As Long, j As Long, evenRow As Boolean, firstRow As Long
i = 0
j = 0
firstRow = Range("data").Cells(1).Row
For Each cell In Range("data")
evenRow = (cell.Row - firstRow + 1) Mod 2 = 0
If evenRow Then
Range("startHere").Offset(j, 1).Value = cell.Value
j = j + 1
Else
Range("startHere").Offset(i, 0).Value = cell.Value
i = i + 1
End If
Next cell
End Sub
How does this macro work?
Before jumping in to the lines of code and demystifying the logic, Let’s understand what we need to do:
- For each cell of data,
- If it is in odd row, put the cell data in Date column at end
- Else, put the cell data in Value column at end
- Repeat
This is what our code is trying to do.
Let’s examine the For Each loop, as this is the most critical part of our macro.
- For each cell in the range data
- We check if we are in evenRow using simple arithmetic on row numbers
- If we are in evenRow then
- We put the cell value in row j (number of values so far), column 2
- We increment j
- Else
- We put the cell value in row i (number of dates so far), column 1
- We increment i
- Close the IF condition
- We check for next cell in the data range
Advantages of Transformation over SUMIFS approach
Both options for transforming data have few advantages:
- They work with any type of data (unlike SUMIFS, which works only for numeric lookups and has few other issues)
- Once data is restructured, you can do other types of analysis like creating pivot tables, adding extra calculated columns etc. easily.

How would you transform data?
My favorite techniques for transforming data are – VBA, formulas, Power Query, pivot tables & SQL. Depending on the situation, time availability, where my data is, I choose one of these options to scrub my data.

Hi
I downloaded cube-formula-slicer-selection.xlsx.
Why is 'Report Connections' grayed out?
Great article!! Thank you very much... This post is one of the most helpful for my job!
Great Introduction. Thanks very much.
Wow! trying to use this on the reports that I have now. I really liked that Quantity and Amount Bar graph used on the pivot-multi tab, but for the life of me, I can't seem to replicate it from scratch. Help please?

This is awesome! I will favorite this page in my blog, http://www.exceltoxl.com
Since I've known slicers about 2-3 yrs ago, I've pretty much used them in every damn report I do. Everyone that sees it for the first time is like "This is the best thing ever. Did you do that using excel or something else?" 😀 My bosses are so used it that when they see a report from someone else that doesn't have slicers they send it to me to redo it :).
Couple of tips:-
Tip 1:
If for lack of space or say you want ability to search within a filter due to numerous values being present but still want it to connect to multiple pivot tables or charts then
1. Setup a pivot table with just the report filter
2. Create a slicer with the same field and tie that to all the pivot tables/charts that you want.
3. Just place it some out of sight.
Now you have a dropdown with all your values with search option plsu it is also connected to all your charts and pivot tables.
TIP 2:
In Excel 2013, slicers can be used with just plain tables as well. Not limited to pivot tables.
Congrats!
Nice content : )
Very comprehensive. Explained in an extremely simple way. I have been using Slicers for a while, but still learnt new things from this post. Thanks for sharing. Best wishes.
Awesome Explanation !!
I have joined this blog recently. Brilliant tools are available that I started using in my day to day work. Brilliant site. Thanks heaps.

Oh wow. I've only just started using Excel 2010 and had no idea this even existed. It makes dynamic charts so much easier!
You are my Hero! I am working with PowerPivot due to the huge amount of data I have and could not use my usual tricks to get the scatter chart title to change. For some reason the CUBE function wouldn't work (who knows why, I don't have time to dig into it now) but your "dummy" solution did.
thankyouthankyouthankyou!

On a normal PivotTable filter, you can choose whether to allow multiple items to be selected or not. Is that possible with slicers (in Excel 2010)? I've had a look through the options and not found a way to do it yet!
Hi Stevie... this is not possible with slicers.
Just hold down control when you're choosing them...can then either click another (without control) and it will show only the new one, or click the filter with the red 'x' to revert back to all options.
Not a limitation that can be placed on the slicer but still a potential workaround depending on your needs.
Very comprehensive note on slicer. I haven't yet used ms excel 2010, but learnt Slicer tool very well
How should I apply Slicer in excel 2010 version, not able find options
as directed, could you please tell me that step by step
@Arif
In Excel 2010 slicers could only be applied to Pivot tables/Charts not Regular tables

I have a longitudinal line graph with the count of exams scored at each level(1-4). I need a longitudinal line graph that shows the percentage for each level. I made my pivot with the count in the field settings with a calculation of % of row total. This works great until you add a slicer fo that you can look at one level at a time. When I do this, it shows as 100% because it seems to lose the rest of the row calculations. How can I set it up to show the percent. I do not have the option of adding it to my data table. I am using straight Pivot, not PowerPivot.
@Mary
I'd suggest asking the question in the Chandoo.org Forums http://forum.chandoo.org/
Attach a sample file with an example of what you are after, even hand drawn
Hi, thanks for these tips. Is it possible to link a slicer to *different data sets*? All my data sets have a "year_opened" and "month_opened" fields, and I'd like do a single filter and update everything at once. Is that possible?
Hi,
Can someone tell me how to format a date field in a slicer to tell July 2016 instead of 07/31/2016?
Thanks in advance.
Great post - easily explainable for non excel whiz.
Thanks for the slicers post. I'm knew to this feature so don't be to harsh on me 🙂
In the example bar chart graph: "Quantity breakup by Customer Profession and & Product category" you get a different picture depending on which area is chosen "East, Middle, North, South, West". That part I get. But the graph itself doesn't specify which region you are in.
Is it possible to put the filtered criteria into the Chart title. For example if I chose West, the title would read "Quantity breakup by Customer Profession and & Product category - West".
Is that possible? Just curious. Thanks
It is possible...I have this on a number of my reports.
1) create a pivot table with just the column your slicer is set on
2) assign the slicer to that pivot table
3) create a string in cell B3 (or wherever):
="Quantity breakup by Customer Profession & Product Category- "&A3
(assuming that A3 is the cell that the chosen region appears in)
4) click (once) on the graph title, then in the formula bar type =B3
As you change the slicers, B3 will update as will the chart title.
Couple of tips:
1) if you need to have a new line for the title, use CHAR(10) e.g.
="Quantity breakup by Customer Profession & Product Category"&CHAR(10)&A3
(this will have the region on a new line)
2) if multiple regions will be chosen, I've added in an IF statement
=IF(COUNTA(A3:A10)>1,"Multiple Regions",A3)
(I'm sure there are ways to concatenate the strings but for mine it could get up to 20 and that just gets ridiculous for the graph heading)
Just Wow
I am trying to create a duplicate dashboard using data in one workbook and creating a new workbook to place in a shared file for my coworkers. I have created a separate worksheet in the original workbook for the new pivot charts and slicers I want to use in the new workbook/dashboard. I don't want all of the source data in the new workbook, as it is very large. I am having trouble making new slicers work. They work in the original workbook, but when I copy them to the new workbook they don't work. Am I going about this the right way or is there an easier way?
Very good post! Helped a lot. Keep up the good work!
how can you prevent multiple selection in a slicer box? In short, in any slicer box, only one entry is allowed and not multiple entries.
Fairly new to forum's, hoping I'm not breaking a rule here, but I found this forum which seems to provide a solution:
https://wessexbi.wordpress.com/2014/03/17/just-one-slice-please/
I have 2 files. (1. .xlsx 2. .xlsm)
1 file contains all the pivot tables and charts. its also macro enabled.
2nd file contains the source data which is a .xlsx file.
but I am unable to run slicer on my 1st file.
can anybody help me out?
chandoo.org: one of my favourite Excel sites for years.
Slicers tutorial: excellent as usual.
Animated gifs: sorry, but REALLY distracting!! Especially with two on the same screen. Is there any way they can be activated only when we click on them, or something?
Hi Team,
I have inserted a slicer to a pivot table with 4 fields...I need to add another field for the same slicer...help me with this..
First of all I would like to say terrific blog!
I had a quick questio in whiich I'd like to ask if you don't
mind. I was intereested to know how you center yourself and clear your head
before writing. I've had a hard time clearing my mind in getting my ideas out there.
I do enjoy writing however it just seems like the first 10 to 15 minutes are generally lost simply just tryying to figure out how
to begin. Any recommendations oor tips? Many thanks!
Hi All
Im trying to connect a slicer to 2 pivot tables with different sources
Both data tables have been sorted and have duplicates
ie
Table 1
Name Week FTe
A 1 7.2
A 2 7.3
B 1 7.3
B 2 7.3
Table 2
Name Month Fte
A Jan 2.6
A Feb 3.2
A Mar 4.4
B Jan 2.2
B Feb 6.4
B Mar 2.2
etc
I have created 2 pivot tables and have sorted it out the way i want with charts etc
Now all i want is to connect the Name Slicer to be connected to both of those pivot tables but problem is they have duplicates and are from different tables/sources
how can i connect/add this to a data model and connect to my name slicer?
Im sure it maybe something simple but minds not with it
So in short 1 to connect 1 slicer to 2 different pivots from different sources but not all pivots (There are dups in both) - as shown in the example
Thank You
Hi H
This is how you can do it. Create a third table with all slicer options (in this case it would be Name column) with one row per unique value. Now add this table to your source list. Then link all two tables via this third table thru Data ribbon > Manage relationships feature. Finally add a slicer on this third table column and link the slicer to both pivot charts.
Please note that you need to construct the tables and charts after data model is created.
See this page for more explanation on how to use relationships - https://chandoo.org/wp/introduction-to-excel-2013-data-model-relationships/
Hi,
Using Cube Value with Slicers is great. I am new to cube value, but it is so powerful. I am stuck on an issue where I want to filter on a slicer for all values except 1 and the slicer has thousands of values. I get #N/A in the results, when trying to do this. Any ideas on how to do an exception calc or how to get around this with the multi select slicer functionality?
Thanks in advance.
Cyleste
@Cyleste... thanks for your comments and welcome to Chandoo.org. You can use DAX to calculate such things as Excel pivot tables alone cannot function like the way you want. You can use DAX formula EXCEPT() to achieve this. For example,
=CALCULATE(SUM(data[sales]), EXCEPT(ALL(data[filter_column]), VALUES(data[filter_column]))) can tell you the sum of [sales] column in the data table by ignoring slicer selected values.
Hope that helps.
Hi Chandoo,
Thank you for your quick reply. I am not familiar with DAX but it sounds like I won't be able to apply the calculation you provided after converting the power pivot to excel formulas via OLAP.
Cyleste
Thanks Chandoo, I like yours tricks & always I use slicers. Regards from México.
Hi Chandoo,
I have a lot of text in the slices (Pivot table). The text is not completely visible. What should I do?
Please Help
Thanks
Hi Girish,
Slicers are useful only for items with short text, for ex: categories, product names etc. For longer values, you are better off using form controls for interaction - Here is an overview of form controls Form Controls – Adding Interactivity to Your Worksheets
Thanks so much for this, it's brilliant! I think it's almost there - I've actually followed the steps on the example linked in my post. I just can't get it to filter properly; it just returns 0 when I add a date into Cell O2. Should I be doing it differently?
slicers dont work with non-admin roles in OLAP Pivot Tables
