## Pulling Unique Lists from Columns That Aren't Adjacent

We received a great question from Irene, who is an **Elevate Excel member**. She's curious to know if the **UNIQUE function** can be used to pull entries from **columns that are not side by side** or next to each other.

The answer to Irene's question is: **on it's own, the UNIQUE function can only find unique combinations from adjacent columns**. However, we can write a formula to work around that. This formula will essentially create an array of the non-adjacent columns that you want to reference in the UNIQUE function.

It's a similar process to what I explained in this tutorial on the FILTER Formula to Return Non-Adjacent Columns in Any Order.

Here's how to write the formula we need:

## Use INDEX to Create an Array for Non-Adjacent Columns

Below is an example where we want to use the **UNIQUE function**, which is a dynamic array function, to **return a list of unique combinations** of Customer Names and Product Names. As you can see, those two columns are not next to each other.

Since the UNIQUE function does not handle that on its own, we have to use use another formula to help. So we're going to use** INDEX**.

For the **INDEX function**, the first argument is the **array**. We will **select the entire table** for the array.

The next argument is **row number** (row_num). To define the row numbers we want, we'll first create a list of row numbers using the **SEQUENCE function**.

The first argument (and the only one we need) in SEQUENCE is **rows**. To define **rows**, we will actually use the **ROWS function**. The only argument for the ROWS function is **array**, and for that, we will **again reference the entire table**. This will return every row from the table to our new array.

To define the **column number argument** (column_num), we can reference column numbers as an array in curly brackets. In our case we want to pull from **columns 1 and 3.** Those column numbers are specific to the table we're working with, not the sheet overall.

So, all together, our **formula to return an array of non-adjacent columns** looks like this:

=INDEX(tblUnique,SEQUENCE(ROWS([tblUnique]),{1,3})

## Wrap the Formula with UNIQUE

Now that we've created a spill range that shows the columns we want, we simply have to **wrap our existing formula with the UNIQUE function**.

The UNIQUE function has other arguments, but the only one we need to use is **array**. Our array is defined by the formula we already created. So the final formula looks like this:

=UNIQUE(INDEX(tblUnique,SEQUENCE(ROWS([tblUnique]),{1,3}))

With our duplicates filtered out, **our spill range only shows unique entries** from the two columns we wanted to pull from.

## Conclusion

You can then sort the list of unique values by wrapping the formula in the SORT or SORBY function. Or you could further filter down the results with the FILTER function.

The possibilities are endless in terms of what you can do with dynamic arrays to create flexible, interactive reports. Checkout our video & post on Dynamic Array Formulas & Spill Ranges to learn more.

This good insight never thought of this. Thanks

Thanks Paul!

This is really helpful! Could you take it 1 step further and look for counts of each of these unique combinations as well?

Thanks!

Hi Dan,

Great question! Yes, it is possible and there are several ways to go about it. With formulas you could use a COUNTIFS function.

=COUNTIFS(tblUnique[Customer Name],F4,tblUnique[Product Name],G4)

You could also use a pivot table to create the summary report.

I hope that helps. Thanks again and have a nice day!

Thank you Jon for this Video. I have a question. If I want to get the dates sequence , which is only Saturday& Sunday for 3 months. How can I do this?

Hi Rahul,

Great question! This is also possible with dynamic array formulas. Here is a formula that uses SEQUENCE and FILTER. It assumes the start date is in cell M5 and end date in M6.

=FILTER(SEQUENCE(M6-M5,,M5),WEEKDAY(SEQUENCE(M6-M5,,M5),2)>5)

We’ll add this formula to our list for future videos. The SEQUENCE function has a lot of uses with dates.

Thanks!

Hi Jon,

why i dont have SEQUENCE and UNIQUE function?

Hi Jon

Thanks for sharing you can also use the CHOOSE function to join ranges together like this.

=UNIQUE(CHOOSE({1,2},A2:A6,D2:D6))

I can’t find Sequence function in Excel 2019. Is it replaced by some other function in this version of excel?
