Let me ask you a couple of quick questions to make sure I fully understand your problem.

Excelchat Expert
16/10/2018 - 08:22

Do you want to share a document where you have a problem?

User
16/10/2018 - 08:22

No!

Excelchat Expert
16/10/2018 - 08:23

Okay, could you please share the sample of your data on the sheet near the chat, so we could make a solution based on it?

User
16/10/2018 - 08:24

Sure

Excelchat Expert
16/10/2018 - 08:26

Okay, so in this example, you would like to have the result in the column near the table A:C, right?

Excelchat Expert
16/10/2018 - 08:27

It is enough for the sample, thank you

Excelchat Expert
16/10/2018 - 08:27

Could you please show and explain the expected result?

Column C has the correct name I am looking for

User
16/10/2018 - 08:29

If the name on column B matches the name on column C, I want to copy the email from column A to column D

Excelchat Expert
16/10/2018 - 08:29

So for row 1, we need to do the following, right? If Name from B1 exists in column C, then we return the email from the same row, right?

User
16/10/2018 - 08:29

Correct!

Excelchat Expert
16/10/2018 - 08:29

If B1 exists in C2, we need to take email from A1 or A2?

User
16/10/2018 - 08:30

Not really. If B1 exists in C2 through C8, copy A1 to D1

User
16/10/2018 - 08:30

Sorry, C1 through C8

Excelchat Expert
16/10/2018 - 08:31

Okay, got it

Excelchat Expert
16/10/2018 - 08:31

Will make the solution in few minutes and explain that to you after that

Excelchat Expert
16/10/2018 - 08:32

Okay, your result is ready at column D

Excelchat Expert
16/10/2018 - 08:33

If the name from column B exists in column C, then we return the email from column A

User
16/10/2018 - 08:33

But I did not see it working on D8.

Excelchat Expert
16/10/2018 - 08:33

Annada Clarke doesn't exist in column C

User
16/10/2018 - 08:33

There is no match for D8 on column B

Excelchat Expert
16/10/2018 - 08:33

So for D8

Excelchat Expert
16/10/2018 - 08:33

It should check if B8 exists in C1:C8, right?

Excelchat Expert
16/10/2018 - 08:34

And if yes, we return A8, right?

User
16/10/2018 - 08:34

And it is giving me a positive result.

Excelchat Expert
16/10/2018 - 08:34

On our sheet the result is available only at D1,D6 and D7, since B1, B6 and B7 exist in column C

User
16/10/2018 - 08:34

I am actually referring to cell D6

Excelchat Expert
16/10/2018 - 08:35

It exists in C5

Excelchat Expert
16/10/2018 - 08:35

That is why we show the email from A6

Excelchat Expert
16/10/2018 - 08:35

Because B5 was found in columnC

User
16/10/2018 - 08:35

The result on D6 should actually be on D5

Excelchat Expert
16/10/2018 - 08:35

I mean B6 was found there

Excelchat Expert
16/10/2018 - 08:36

So in fact you need to check if C5 exist in column B?

Excelchat Expert
16/10/2018 - 08:36

And if yes, return email from that row?

User
16/10/2018 - 08:36

That is correct.

User
16/10/2018 - 08:36

Correct!

Excelchat Expert
16/10/2018 - 08:36

Okay, will remake it, few minutes please

Excelchat Expert
16/10/2018 - 08:37

Is it correct now?

Excelchat Expert
16/10/2018 - 08:39

So now in D1 we check if C1 exists in column B. If yes, we return the email related to the found position in column B

User
16/10/2018 - 08:39

4 is not wokring

Excelchat Expert
16/10/2018 - 08:39

It is working, it found the name in B4 and returned email from the same row

Excelchat Expert
16/10/2018 - 08:39

I see that you also have this name in B5

Excelchat Expert
16/10/2018 - 08:39

But Excel will find the first occurrence of the name

User
16/10/2018 - 08:40

It is working now.

User
16/10/2018 - 08:40

That is it.

User
16/10/2018 - 08:40

How much do I owe you?

Excelchat Expert
16/10/2018 - 08:41

You don't have to pay me, probably you are having a free session or an unlimited sessions plan

Excelchat Expert
16/10/2018 - 08:41

Do you have any questions about the solution?

Excelchat Expert
16/10/2018 - 08:41

The formula for D1 is:

Excelchat Expert
16/10/2018 - 08:41

=iferror(index(A:A,match(C1,B:B,0)),"")

Excelchat Expert
16/10/2018 - 08:41

So we try to get the data from column, based on the match of name from Column C in Column B

Excelchat Expert
16/10/2018 - 08:42

Index return an error function if it couldn't find the result, so if we get an error, we show nothing (double quotes, "")

User
16/10/2018 - 08:42

Give me a moment, please. I am trying it.

User

It seems that I need to create an index for this to work.

Excelchat Expert
16/10/2018 - 08:44

What do you mean by creating an index?

Excelchat Expert
16/10/2018 - 08:44

For this solution, we need to use the combination of Index + Match function, and IFERROR to handle the error results

Excelchat Expert
16/10/2018 - 08:44

Index allows to show the content from the specified range, and number of rows and column in it to show the cell

Excelchat Expert
16/10/2018 - 08:45

Match allows to find the position of the value in the range

Excelchat Expert
16/10/2018 - 08:45

IFERROR allows to show a custom output instead of error

User
16/10/2018 - 08:45

How do I create the index?

Excelchat Expert
16/10/2018 - 08:45

You just activate the cell where you need to have the formula

Excelchat Expert
16/10/2018 - 08:45

And type it there

Excelchat Expert
16/10/2018 - 08:45

For D1 the formula is

Excelchat Expert
16/10/2018 - 08:45

=iferror(index(A:A,match(C1,B:B,0)),"")

Excelchat Expert
16/10/2018 - 08:45

Then we just drag this formula down, and it works for all the range that we need

User
16/10/2018 - 08:46

I don't know how to create the index.

Excelchat Expert
16/10/2018 - 08:46

INDEX is just the name of the function

User
16/10/2018 - 08:47

OK!

Excelchat Expert
16/10/2018 - 08:47

You don't need to create it, you just write index with your keyboard

Excelchat Expert
16/10/2018 - 08:47

it is like a small coding

Excelchat Expert
16/10/2018 - 08:47

So in D1 we used the INDEX function, which means:

Excelchat Expert
16/10/2018 - 08:47

That we try to get the value from range A:A (column A, the required email)

Excelchat Expert
16/10/2018 - 08:48

In order to know which row do we need to take from this range, we use the MATCH function

Excelchat Expert
16/10/2018 - 08:48

With MATCH function, we find the position of C1 in the column B. Then we pass this value to the INDEX function, and it knows from which row do we need to have the result

Excelchat Expert
16/10/2018 - 08:48

In some cases we won't find the name from column C in column B

Excelchat Expert
16/10/2018 - 08:48

In this case we would see an error "#N/A"

Excelchat Expert
16/10/2018 - 08:49

In order to prevent it, we use the IFERROR function, which shows nothing instead of the error in this case

Excelchat Expert
16/10/2018 - 08:49

That is all the logic which we used to solve your problem

Excelchat Expert
16/10/2018 - 08:50

So when you will implement this solution in your real file:

Excelchat Expert
16/10/2018 - 08:50

=iferror(index(A:A,match(C1,B:B,0)),"")

Excelchat Expert
16/10/2018 - 08:50

A:A - the column with your emails

Excelchat Expert
16/10/2018 - 08:50

C1 - the cell where you have the name which needs to be checked if it exists in another column

Excelchat Expert
16/10/2018 - 08:50

B:B - the column where we check if C1 exists

Excelchat Expert
16/10/2018 - 08:50

Pretty simply

Excelchat Expert
16/10/2018 - 08:51

Please let me know what questions you might have about the solution

User
16/10/2018 - 08:51

It is working.,

16/10/2018 - 08:51
