# Product Combinations bought by Customers

1. ## Product Combinations bought by Customers

I have a Table that depicts all customers and the products they have purchased. There are about 250 Products and about 500 Customers for total of about 2800 Product Client combination. I am attempting to figure out the various types of combinations of products that are frequently purchased.

Additionally, I have some standard combinations of products that I have grouped together and would like to see what accounts have that grouping of products.

How would I accomplish this ?

Any assistance is appreciated.

Thank You for the guidance. I have enclosed a sample file and I would like to interrogate the data to see :
a) What are the frequently purchased combinations of products in order of reducing frequency : Who are the clients buying each combination ?
b) How many and which clients are buying Combo 1 or Como 2 or Combo 3 etc. in the master list ?

Hi, welcome to the forum

Actually, there are potentially 1250000 Prod/Client combos

To best describe or illustrate your problem you would be better off attaching a dummy workbook. The workbook should contain the same structure and some dummy data of the same type as the type you have in your real workbook - so, if a cell contains numbers & letters in this format abc-123 then that should be reflected in the dummy workbook.

To attach a file to your post,
click advanced (next to quick post),
scroll down until you see "manage file",
click that and select "add files" (top right corner).
click "select files" find your file, click "open" click "upload" click 'done" bottom right. click "submit reply"

Once the upload is completed the file name will appear below the input boxes in this window.
You can then close the window to return to the new post screen.

Thank You Ford for the recommendation. I have updated the thread appropriately.

Im thinking that you will need to 1st ID all prod/client combos for this, and I can think of 2 ways to start this off

1. Create a table with a vertical list of customers and headings for Prods, then use COUNTIFS.
I started mt table in I1 (empty), with Prod starting in I2 and names in J1
J2=COUNTIFS(\$B:\$B,\$I2,\$A:\$A,J\$1)
copied down and across as needed

OR
use a Pivot Table with Client as Column and Product for rows and Values

Once you have this summary, you can start doing your extracts

The problem you describe sounds to me like "market basket analysis" -- a common analysis. It's not an analysis I do, but I am aware of it. A quick internet search for "market basket analysis excel" turned up:
A tool if not built into Excel, available to Excel users from Microsoft: https://docs.microsoft.com/en-us/sql...ql-server-2014
This blog post: http://www.data-mania.com/blog/marke...ysis-in-excel/
This one, whose author included PhD behind his/her name: https://people.revoledu.com/kardi/tu.../MarketBasket/
And several others. Market basket analysis is a fairly common analysis in many programming languages, and Excel/spreadsheets are no different. You might see if any of these tools/essays are useful for you.
