29/09/2017 - 03:46

Are you able to upload a sample document so I can fully analyze your file and give you the best solution?

User

Excelchat Expert
29/09/2017 - 03:50

Yes, it's the one with #NULL!?

User
29/09/2017 - 03:50

i want to remove the duplicates from the column N

User

the last one

Excelchat Expert
29/09/2017 - 03:50

Okay, can you give me an example of duplicates?

User
29/09/2017 - 03:50

like benzodiazepines

User
29/09/2017 - 03:51

which is repeated 2tice

Excelchat Expert
29/09/2017 - 03:51

Can you reference the cells where they show up?

Excelchat Expert
29/09/2017 - 03:51

N15 and which one?

User
29/09/2017 - 03:51

yes

User
29/09/2017 - 03:51

n15

User
29/09/2017 - 03:51

and n3

Excelchat Expert
29/09/2017 - 03:51

I see.

Excelchat Expert
29/09/2017 - 03:52

Here's what we can do, since you don't want to delete them all at the same time, what we can do is tag them if they are duplicates.

User
29/09/2017 - 03:52

i want to remove these duplicates from all my data which a around 10000 cases

Excelchat Expert
29/09/2017 - 03:53

If you'll look at column O, you'll see numbers.

Excelchat Expert
29/09/2017 - 03:53

Do you see them?

User
29/09/2017 - 03:53

yes

Excelchat Expert
29/09/2017 - 03:53

Okay, let me explain what this means.

Excelchat Expert
29/09/2017 - 03:53

EVERYTHING that isn't 0 or 1 means they are duplicates.

Excelchat Expert
29/09/2017 - 03:53

For instance, you will see the first Benzodiazepines

Excelchat Expert
29/09/2017 - 03:53

Has a value of 1

User
29/09/2017 - 03:53

yes i see

Excelchat Expert
29/09/2017 - 03:54

But then the next one, has a value of 2.

Excelchat Expert
29/09/2017 - 03:54

What you can do then is to filter everything that is greater than 1.

Excelchat Expert
29/09/2017 - 03:54

I did the filtering and got these results.

Excelchat Expert
29/09/2017 - 03:55

If you'll look at the document preview, here's all the entries that are duplicates.

User
29/09/2017 - 03:55

i see

Excelchat Expert
29/09/2017 - 03:55

Now you can do anything you want to do to them.

Excelchat Expert
29/09/2017 - 03:55

You can either delete the entire row

Excelchat Expert
29/09/2017 - 03:55

Or just those specific cells.

Excelchat Expert
29/09/2017 - 03:55

It is really up to you.

Excelchat Expert
29/09/2017 - 03:55

So just copy the formula in column O and apply it to your file up to row 1000

Excelchat Expert
29/09/2017 - 03:56

Or whatever the maximum number of records you have.

User
29/09/2017 - 03:56

but the problemm is i have 1000 od benzodiazepines, is there anyway that this function can automatically remove duplicate from each case?

Excelchat Expert
29/09/2017 - 03:56

Then you should easily be able to filter everything that is greater than 1.

Excelchat Expert
29/09/2017 - 03:57

The remove duplicate function in Excel would that but that's not the effect you want?

User
29/09/2017 - 03:57

no its not

User
29/09/2017 - 03:57

it assume the whole column as one and removes all of my cases

User
29/09/2017 - 03:57

as most of the drugs are same

User
29/09/2017 - 03:57

i have like 10 different drug

Excelchat Expert
29/09/2017 - 03:57

I'm not sure I understand.

User
29/09/2017 - 03:58

which each patients use couple of thems

Excelchat Expert
29/09/2017 - 03:58

Can you elaborate on what you meant by it assume the whole column as one and removes all of my cases

User
29/09/2017 - 03:59

i want the excel that do the duplicate function separately for each of my case. like having a different border and it only removes the similar from the box

Excelchat Expert
29/09/2017 - 03:59

You will have to give me an accurate example because I'm not able to visualize your request.

User
29/09/2017 - 03:59

not from the whole column

Excelchat Expert
29/09/2017 - 04:00

I don't see borders or each case in your example.

User
29/09/2017 - 04:00

thats the problem, let me draw a border then i can explain it to you, can I text you in 5 mins

User
29/09/2017 - 04:00

Excelchat Expert
29/09/2017 - 04:01

Excelchat Expert
29/09/2017 - 04:01

A gentle reminder that since you've extended the session: Please ensure that you end the session properly later or else I'll be stuck here waiting for the timer to expire and I'll be unable to help others.

User
29/09/2017 - 04:03

User
29/09/2017 - 04:03

thanks a lot

Excelchat Expert
29/09/2017 - 04:03

I can see that you deleted N15

Excelchat Expert
29/09/2017 - 04:03

What else did you do?

User
29/09/2017 - 04:03

i removed to duplicates

User
29/09/2017 - 04:03

manually

User
29/09/2017 - 04:04

2

Excelchat Expert
29/09/2017 - 04:04

How will Excel know that something is part of a group?

Excelchat Expert
29/09/2017 - 04:05

Is it thru column A?

User
29/09/2017 - 04:05

thats the problem, i want to separate the column for each of my cases

User
29/09/2017 - 04:05

yes

Excelchat Expert
29/09/2017 - 04:05

If that's the case then you can do it if you have column A filled.

Excelchat Expert
29/09/2017 - 04:05

Like this:

User
29/09/2017 - 04:05

how?

Excelchat Expert
29/09/2017 - 04:08

Using the formula in column O and P, you'll be able to detect the duplicates in each Case.

User
29/09/2017 - 04:08

how? can you explain it please?

Excelchat Expert
29/09/2017 - 04:08

If you'll look line 41, it should've been a duplicate earlier, but since it is a different case, it was not counted as a duplicate.

Excelchat Expert
29/09/2017 - 04:09

Caffeine & Theobromine already existed above for case 15-11510 but since row 41 has a different case number, it was not counted as a duplicate.

Excelchat Expert
29/09/2017 - 04:09

With this, you can just filter COlumn P for values >1

User
29/09/2017 - 04:10

so it just checks the duplicate for each case?

Excelchat Expert
29/09/2017 - 04:10

Yes, exactly!

User
29/09/2017 - 04:10

how did you transfer the text to the numbers? sorry i didn't get it?

Excelchat Expert
29/09/2017 - 04:11

I used a concatenate.

Excelchat Expert
29/09/2017 - 04:11

A3&N3

Excelchat Expert
29/09/2017 - 04:11

The & symbol combines the values of cells.

User
29/09/2017 - 04:12

im a bit lost, did realize how you did it

Excelchat Expert
29/09/2017 - 04:12

Okay, here are the steps.

Excelchat Expert
29/09/2017 - 04:12

First, column A must be filled.

Excelchat Expert
29/09/2017 - 04:12

Second, apply this formula in column O

Excelchat Expert
29/09/2017 - 04:12

=if(N3="","",A3&N3)

Excelchat Expert
29/09/2017 - 04:12

Then drag downwards to apply to everything

Excelchat Expert
29/09/2017 - 04:13

Then apply this formula in column P:

Excelchat Expert
29/09/2017 - 04:13

=if(O3="",0, countif($O$3:O3,O3))

Excelchat Expert
29/09/2017 - 04:13

And drag downwards too.

Excelchat Expert
29/09/2017 - 04:13

Column P will give you numbers, those number mean if they are duplicates in the same case number.

Excelchat Expert
29/09/2017 - 04:13

You are just concerned about anything that is >1

Excelchat Expert
29/09/2017 - 04:13

So filter column P and uncheck all 0s and 1s.

User
29/09/2017 - 04:16

so thats it? anything else that i need to do?

Excelchat Expert
29/09/2017 - 04:16

That's all you need to do.
