VLOOKUP is a super popular formula but suffers from a major drawback. You can’t lookup data to the left!

However, there’s a sneaky trick that lets us VLOOKUP to the left, so we can search for a term and return a result from a column *to the left* of the original search column:

# How do we create a leftwards VLOOKUP?

What we do is create a new virtual table with an array, where the columns are switched, so the VLOOKUP can work on this temporary, virtual table.

## What’s the formula?

Let’s assume we have data in columns A and B. I want to search column B and return the value from column A, then we use:

## Can I see an example worksheet?

## How does this formula work?

Imagine this is your raw data table and you want to search for a name and return the rent figure:

The first step is to use an array formula to create a new table on the fly, and then perform the VLOOKUP on this new temporary table.

This formula creates the temporary table:

as shown in the following image:

This formula has curly brackets to denote an array and inside, the two columns are swapped. This creates an array output with the two columns reversed.

*Note, they don’t have to be adjacent columns, they just happen to be in this simple example.*

Next, this formula performs a vlookup on the new temporary table (which is all done inside the vlookup, so you won’t actually see the temporary table):

which effectively performs a search like so:

Bingo!

It returns $2,214 as we want.

*Note: A better way to solve this is by using a combination of the INDEX and MATCH functions.*

Thank you so much. I was looking for a way to do this. I’m not sure why I didn’t think of just creating a temporary array.

I’ve used index & match before but they do not work well when they are nested in the arrayformula() function. This works perfectly though.

I can’t use {} formula because it makes two column staked on one column. How to solve it?

Thank you for your help 🙂

Hey Marcell,

Try using a backslash instead of a comma and that should do the trick to give you the two columns side by side:

`={B1:B10\A1:A10}`

(I’m presuming you’re based in one of the European countries that use commas as decimal operators.)

Cheers,

Ben

wow, thanks! Helps me a lot! 🙂

Bravo! Quick and simple explanation.

Very Nice – helped me complete an update to a current function.

…here is my working snippet which shows looking up in another table:

=IFERROR(VLOOKUP(VLOOKUP(A2,PlayerNameMapping!A:D,2,false),{RGdownloadProj!$E$1:$E$1000,RGdownloadProj!$A$1:$A$1000},2,false), “”)
