Let’s say you are starting at a large data-set with multiple columns. You need to make a pivot report from it for a client or manager. How would you go about it?

This is the exact problem Jo, my wife faced the other day. She came home and after catching up on each other’s day, she asked me how I would do it. That got me thinking. This blog post is born out of that rumination.
Large data-set? Tell me more:
Imagine you have sales data which customer bought products in each city of operation. Say, you have 100s of customers, operate in 50 major cities and sell 16 different products. If you try to make a pivot table with all these fields, you will end up with a monstrosity of 5000 rows. Nobody can read that pivot and make any sense.

What now?
Ideas for creating pivot tables from large data-sets
Here is a list of five ideas to use when you need to create pivot tables from large data-sets.
Idea #1 – Add slicer to one of the fields
Even though you have many fields, chances are the report user wants to focus on one of the elements to start conversation. Add it a slicer. (Related: Introduction to Excel Slicers)

Idea #2 – Show just top values
You can apply value filtering on pivot tables to show just the top performing customer (or product, city etc.). This will greatly reduce the size of your pivot table. You can also collapse a sub-level detail so that user can press + if they want to see details.

To set top 1 filter, simply click on the filter icon on field you want to set it, go to value filters > top 10 and then set it to top 1.

Idea #3 – Individual pivots with drill down option
You can double click on any number in pivot tables to see detail rows that add-up to that number. We can show summary pivot tables from large data-sets instead of full-blown ones. Here is an example.

Idea #4 – Set up support table to show top 3 vs. other view
You can categorize fields like products, customers etc. by introducing an extra table that splits them in to groups. For example, we can categorize products to two types:
- Top 3 products: Most selling products across all our data
- Other products

Once you have such a table, you can connect this product.types table to original data using relationships and then build a multi-table pivot.

Idea #5 – Add two-level filtering by alphabets
When using fields like customers or products, you cannot easily apply slicer or report filter on them. This is because such fields have 100s of values usually. One way to reduce the clutter is by introducing two-level filtering.
We can easily do this by adding an extra column to our data to calculate the first letter of customer name. (something like =LEFT([@customer],1) will do.
Once you have such new field, you can set up a multi-level filtered pivot report like below.

I've just taught yesterday to a colleague of mine how to convert amounts in local currency into another by pasting special the ROE.
great thing to know !!!
Chandoo - this is such a great trick and helps save time. If you don't use this shortcut, you have to take can create a formula where =(ref cell /100), copy that all the way down, covert it to a percentage and then copy/paste values to the original column. This does it all much faster. Nice job!
I was just asking peers yesterday if anyone know if an easy way to do this, I've been editing each cell and adding a % manually vs setting the cell to Percentage for months and just finally reached my wits end. What perfect timing! Thanks, great tip!
If it's just appearance you care about, another alternative is to use this custom number format:
0"%"
By adding the percent sign in quotes, it gets treated as text and won't do what you warned about here: "You can not just format the cells to % format either, excel shows 23 as 2300% then."
Dear Jon S. You are the reason I love the internet. 3 year old comments making my life easier.
Thank you.
Here is a quicker protocol.
Enter 10000% into the extra cell, copy this cell, select the range you need to convert to percentages, and use paste special > divide. Since the Paste > All option is selected, it not only divides by 10000% (i.e. 100), it also applies the % format to the cells being pasted on.
@Martin: That is another very good use of Divide / Multiply operations.
@Tony, @Jody: Thank you 🙂
@Jon S: Good one...
@Jon... now why didnt I think of that.. Excellent
Thank You so much. it is really helped me.
Big help...Thanks
Thanks. That really saved me a lot of time!
Is Show Formulas is turned on in the Formula Ribbon, it will stay in decimal form until that is turned off. Drove me batty for an hour until I just figured it out.
