The aim of this tutorial is to create a dependent drop-down list that’s based on a messy Excel Table.
What do I mean by an unsorted Excel table?
The categories for the first drop-down are not in a tabular format and they are not grouped together. You can see an example of the data set below. In a previous tutorial I showed you how you can extract unique items for a data validation drop-down list that was based on a table which had multiple instances of each category.
In this tutorial I will take this one step further and create a dependent drop down list based on the same data set.
Great thing is: to get there we need to overcome a set of challenges.
First: How to Find Many Matches
To get to our dependent data validation list, we need to be able to extract all records for each category (in the example, all apps belonging to each division). My approach is to use the INDEX together with AGGREGATE function in order to come up with a CSE (Control Shift Enter) free version of the formula.
Second: Absolute Column Table Referencing
The second challenge is to fix the column referencing in the table so that it’s fixed and doesn’t move as we drag the formula
Third: Create a Drop-down List that Excludes Empty Values
Here I use OFFSET together with COUNTIF and OFFSET again, to get a drop-down list that is restricted to the non-empty cells. I will be making a separate video on this in the coming months to explain the technique used in more detail.
AND finally in the end we get to our dependent drop down list :)

thank you so much Ms. Leila you are so good teacher.
Thank you very much Ismail.
These tutorials are amazing and have helped me a great deal in understanding Excel more. I have a quick question regarding this tutorial. If I wanted to include a third column of data, and exclude duplicates from the first and second columns, is there an easy way to address that? For instance if you had duplicates in your app column, and added a third column that does not have duplicates. For instance if you had a first column listed as “Division”, second as “App” which has duplicate values, and third as name assigned where no duplicates take place. The end goal is to have two dependent drop downs after the first drop down is established with the second drop down excluding duplicates and the third showing all as there is no duplicate. Any help would be greatly appreciated, or possibly if you’ve already addressed such an instance in another tutorial. Thank you so much for the tutorials you’ve put up!
Hi Patrick – I think this video might have the answer: https://youtu.be/gu4xJWAIal8
This still only shows two columns of Data. I am with Patrick and need three columns where the second also has multiple instances.
Even i to want same requirement, if you got it just reply back
your excel window open the nice vision to me
