VLOOKUP may not make you tall, rich and famous, but learning it can certainly give you wings. It makes you to connect two different tabular lists and saves a ton of time. In my opinion understanding VLOOKUP, INDEX and MATCH worksheet formulas can transform you from normal excel user to a data processing beast.
Today, lets understand how to use these formulas better.
What is the syntax for Match, Vlookup and INDEX?
Here is the syntax for these three very powerful functions in plain English:

What are vlookup () and match () ?
VLOOKUP and MATCH are your way of asking excel to find a needle in haystack. Imagine you have all your customer contact information in one sheet in the range A1:D5000 in the format phone number, name, city and date of birth. Now you need to find out which customer has the phone number “936-174-5910”. How do you do it?
You guessed it right, you use VLOOKUP and summon excel to do the search and return with customer name.
While VLOOKUP is used to fetch value a based on what you are looking for, MATCH is used to fetch the position of the value you are looking for.
See this illustration to understand :

What does VLOOKUP really do?
Imagine you have a list of data like this:

Now, how do you answer the question – “How many sales did Jimmy make?“
Yes, your guess is right. VLOOKUP is one of the formulas you can use to answer questions like this.
VLOOKUP searches a list for a value in left most column and returns corresponding value from adjacent columns.
So, in our case, we need VLOOKUP to search for Jimmy and return the amount of sales he made from column 3.
VLOOKUP Syntax & Examples:
The syntax of VLOOKUP is simple:
=VLOOKUP( this value, your data table, column number, optional is your table sorted?)
Here is an example to get you started:

[NEW] XLOOKUP replaces VLOOKUP in Excel 365
If you are using Excel 365, you can use the new & improved XLOOKUP function. It offers a shorter & more versatile syntax for performing lookups.
For ex: the same lookup as above will be done with XLOOKUP like below:
=XLOOKUP(“Jimmy”, A2:A14, C2:C14) will lookup “Jimmy” in column A and return sales amount from Column C.

So what is INDEX() then?
INDEX function is your way of telling excel to fetch a value from large range of values. Since MATCH() function can tell us where the data is found, you can then use INDEX() function to extract corresponding data from another column. In this case, we can use MATCH() to find out which row has net sales 1,799 and INDEX() to return the name of the person. Like this:
Find the position of 1,799 in sales: =MATCH(1799, $C$2:$C$14, 0)
The answer will be 8.
To find the 8th person in names list, we can use INDEX() function like this:
=INDEX($A$2:$A$14, 8)
The answer will be Jagjit.

So how are INDEX() and MATCH() linked to each other?
Since MATCH returns the position of the item you are looking for in a list, you can then use this position in INDEX to fetch values surrounding the searched value.
So, we can combine both functions like this:
=INDEX($A$2:$A$14, MATCH(1799, $C$2:$C$14, 0))
This combination is called as INDEX+MATCH formulas.

Finally
Remember, both VLOOKUP and MATCH throw a fail error of #N/A if the value you are looking for is not there. If you want to stop seeing the error, use IFERROR function.
Just use them with some dummy data, play around with arguments and see how you can say “oh yeah, I can do that in few minutes” to your boss next time.

Note: The text-formula above miss a -1. The video is correct.
😀 sorry, I made the exact same mistake as you did - initially - in the video. {0..3} is one thing, and Table.RowCount(replacements) -->3 items ={0,1,2} is another thing.
1st question : you've created a new column to put the replacements in. how ca we replace in the original column without creating a new one ?
2nd question : how can we replace the value in the entire cell and not only the text (Using ReplaceValue instead of text.Replace) ?
Thanks you in advance
Chandoo, I would be very interested to have your answers in both Yassine's questions!
Thank you for sharing,
Vassilis
Thank you for this! I was just doing an assignment where I was having to replace words with other words in my Excel sheet. We are starting with the basics in my class, so I know I don't have a huge list that I would need to find and replace, but this is something that could be useful down the road for me!
Hi
This is nearly perfect for my needs thank you, however I would like just the "replace" to be the result if possible please, I have tried in vain adjusting the formula without success.
Thank you in advance
Thank you! Awesome tip, and very flexible, too.
My find/replace values were in non-adjacent columns of a table containing a bunch of other data. Worked prefectly and I am now a tiny bit less clueless.
Hi!!!
I have the same question that Yassine did.
I need to replace the values in the same column. I don't want to create a new column e then have to remove the old column.
How could I could that?
That's a real fun article. It inspired me to delve deeper into the topic of List.Accumulate. I can see how the function works, but it takes an additional step to imagine how one can use it for more complex applications.
Your example also made it into my article, together with some other use-cases. Would be great to get your opinion on which other areas you would include in the article.
