Slicers are my new favorite feature in Excel. Introduced in Excel 2010, Slicers are like visual filters.
A simple example of slicers:
Let us say you have a sales report (pivot) for multiple salespersons. Since you want to show the report by one person at a time, you used report filters in pivot tables to display this. But you find that switching between regions is a pain using the report filter.
Enter slicers.
Now, you can just click the region name to show the report for that region, like this:
Using Slicers to Switch between Scenarios Dynamically:
Now, we can use slicers creatively to make an interactive scenario manager in Excel, some thing like this:
This technique gives the same outcome as the Display and Select Scenarios using VBA article, but easier to implement
How to use slicers to switch between scenarios?
Step 1: Set up various scenarios in a table
You need to define various scenarios in a table, like this:
Step 2: Create a pivot table from your scenario data
Select the table you created in step 1 and insert a pivot table. Use variable name as row label and variable value in value field area.
Step 3: Insert a slicer for the scenarios
Select anywhere inside the pivot. Now, from options tab, click on Insert Slicer button. Click on Scenarios field to insert a slicer.
Step 4: Create your model, in our case a break-even model
I will skip the explanation of model creation as that is not relevant here.
Once the model is set up, just refer to the pivot table for each of the variable values.
Step 5: Move slicer to Model
Go to the pivot table worksheet and Select the slicer, click CTRL+X to cut it.
Go back to your model worksheet and paste the slicer.
Step 6: Format the slicer
Excel slicers by default show an option to remove the filtered slicer. You can get rid of this button by,
1) Right click on the slicer
2) Go to slicer settings
3) Un-check Display Header option
See aside.
Step 7: Use the slicer to interactively switch scenarios
That is all, our smart scenario switching slicer is ready. Now, you can extend this in many ways. For example, you can write some clever formulas to handle selection of multiple slicers. You can compare between one scenario and another when more than one option is chosen from the slicer. So much more is possible. But I will let your imagination run wild.
Download Example Excel File:
I have made a simple example to demonstrate this technique.
Please download the file and open it in Excel 2010.
Examine the worksheets “Scenario Pivot” and “Model” to understand how the slicer is setup and how this works.
Do you slice?
As I said, Slicers are my new favorite feature in Excel. I have been using them as much as possible because they are simple to use and very powerful.
What about you? Do you slice often? What is your experience like? Please share your ideas and tips using comments.

8 Responses to “Pivot Tables from large data-sets – 5 examples”
Do you have links to any sites that can provide free, large, test data sets. Both large in diversity and large in total number of rows.
Good question Ron. I suggest checking out kaggle.com, data.world or create your own with randbetween(). You can also get a complex business data-set from Microsoft Power BI website. It is contoso retail data.
Hi Chandoo,
I work with large data sets all the time (80-200MB files with 100Ks of rows and 20-40 columns) and I've taken a few steps to reduce the size (20-60MB) so they can better shared and work more quickly. These steps include: creating custom calculations in the pivot instead of having additional data columns, deleting the data tab and saving as an xlsb. I've even tried indexmatch instead of vlookup--although I'm not sure that saved much. Are there any other tricks to further reduce the file size? thanks, Steve
Hi Steve,
Good tips on how to reduce the file size and / or process time. Another thing I would definitely try is to use Data Model to load the data rather than keep it in the file. You would be,
1. connect to source data file thru Power Query
2. filter away any columns / rows that are not needed
3. load the data to model
4. make pivots from it
This would reduce the file size while providing all the answers you need.
Give it a try. See this video for some help - https://www.youtube.com/watch?v=5u7bpysO3FQ
Normally when Excel processes data it utilizes all four cores on a processor. Is it true that Excel reduces to only using two cores When calculating tables? Same issue if there were two cores present, it would reduce to one in a table?
I ask because, I have personally noticed when i use tables the data is much slower than if I would have filtered it. I like tables for obvious reasons when working with datasets. Is this true.
John:
I don't know if it is true that Excel Table processing only uses 2 threads/cores, but it is entirely possible. The program has to be enabled to handle multiple parallel threads. Excel Lists/Tables were added long ago, at a time when 2 processes was a reasonable upper limit. And, it could be that there simply is no way to program table processing to use more than 2 threads at a time...
When I've got a large data set, I will set my Excel priority to High thru Task Manager to allow it to use more available processing. Never use RealTime priority or you're completely locked up until Excel finishes.
That is a good tip Jen...
