If you know the trick for this advanced filter, this is quite easy to do, but if you don’t, well…

…then it’s easy to get lost in nested OR functions inside of FILTER functions and end up stranded in the land of errors.

# How can I use OR logic inside an advanced filter?

In this example I have 10 rows of data in columns A and B, as follows, and I want to retrieve all of the “alpha” and “gamma” values.

Rather than running two separate filter formulas, and then combining the results, it would be nice to be able to write one formula that gives us the desired output.

Thankfully, it’s possible!

Begin with this dataset for our advanced filter example:

## What’s the formula?

`=FILTER(A1:B10,(A1:A10="alpha")+(A1:A10="gamma"))`

We use a ** "+"** for the boolean logic.

## Can I see an example advanced filter worksheet?

## How does this advanced filter formula work?

Consider a basic FILTER function like this one, for example, which returns only data with “alpha” in column A:

`=FILTER(A1:B10,A1:A10="alpha")`

Now, let’s see how the advanced filter works.

The next step is to return all the data that matches “alpha” or matches “gamma”.

We do this by using a ** "+"** as the boolean operator OR inside the second argument of the FILTER function, as follows:

`=FILTER(A1:B10,(A1:A10="alpha")+(A1:A10="gamma"))`

Now, anytime either condition of the filter is satisfied, in other words an “alpha” or a “gamma” in column A is present, then that row of data is returned in our output filtered dataset.

Have you found a use for this advanced FILTER + OR formula? Any questions? Let me know in the comments below!

Hi, phenomenal walkthrough! If I wanted to refer to a cell instead typing in the text how would I go about doing that? For instance instead of “alpha” what if you wanted it to reference A1 where the “alpha” data resided? I keep getting formula parse errors. Thank you much!

Hey Dan,

You can just change the formula to this:

`=filter(A5:B14,(A5:A14=A1)+(A5:A14=B1))`

where I have my data range in A5:B14, and my filter values in A1 and B1 (e.g. alpha or beta or gamma etc.)

Hope that helps!

Cheers,

Ben

Ben, thanks for this. Have a question for you. What if my OR conditions were more complicated? Like, what if my filter is for multiple conditions to be met for both sides of the “or”? I’ll try to explain what I mean. For instance, what if I want it to filter something based on whether A1:A10=”alpha”, B1:B10>5, or if A1:A10=”gamma”, B1:B105)+(A1:A10=”gamma”,B1:B10<5)) but that doesn't seem to be working for me. Any help?

Amazing! Really helps me build out a simple database from a master sheet using different conditions.

Hi Ben

Is it possible to set a “named range” as the filter criteria?

Let’s say I want to use the “OR” function shown in the example, but I have a list of 50 items I want to include in my filter. Do I need to build up 50 “OR” segments in the formula, or is there a way to link to a named range?
