*This user has given permission to use the problem statement for this blog.*

I have two very large sets of numerical data on the same excel file but on two different sheets and I need to compare them and highlight any differences. Data Set number 1 is all just in one column, But data set number two is also in one column but there is a lot of other data that is not relevant. I used a pivot table, to sum up all of the numbers I needed in Data set 2 and then I summed up the numbers in data set 1 and there was a difference so I need to have excel highlight that difference

Ok

Excelchat Expert
08/02/2018 - 03:28

Okay, I understand

User
08/02/2018 - 03:28

So here Ill type up a little example and then maybe you can show me how to do it?

Excelchat Expert
08/02/2018 - 03:29

Sure :)

User
08/02/2018 - 03:29

Can you see what I am doing?

Excelchat Expert
08/02/2018 - 03:29

Yes, got it

User
08/02/2018 - 03:30

Ok

User
08/02/2018 - 03:31

So Basically imagin there is like 5000 data points in row a

User
08/02/2018 - 03:31

and they are all differnt numbers

User
08/02/2018 - 03:31

not just 1

Excelchat Expert
08/02/2018 - 03:31

Okay

User
08/02/2018 - 03:31

So I cant do it by hand

User
08/02/2018 - 03:31

Now I need to compare all of the data from set ID 1003 with the data in A from sheet 1

User
08/02/2018 - 03:32

and highlight differences

Excelchat Expert
08/02/2018 - 03:33

So, are we going to compare exactly A2 at sheet1 vs A2 at sheet2?

Excelchat Expert
08/02/2018 - 03:33

regardless of their set ID?

User
08/02/2018 - 03:34

No thats what I was saying I only want to compare the numbers in Set ID 1003 on sheet 2

User
08/02/2018 - 03:34

So there is other numbers in the way

User
08/02/2018 - 03:34

and the real sheet is like 5000 numbers long so I can just count them by hand, or find where they start or end because it would take to long

User
08/02/2018 - 03:35

So I used a pivot table to find all of the numbers in Set ID 1003

User
08/02/2018 - 03:35

But then I need to know how to compare them to their counterparts in A on sheet 1

Excelchat Expert
08/02/2018 - 03:36

Which column should we place the result,?

User
08/02/2018 - 03:36

Is there a way to highlight the ones that are different?

User
08/02/2018 - 03:36

(Sorry for spelling btw im typeing fast lol)

Excelchat Expert
08/02/2018 - 03:36

no worries

Excelchat Expert
08/02/2018 - 03:37

Okay, can you give me one sample that youn based on your data shown

Excelchat Expert
08/02/2018 - 03:37

So we can set the formula for highlighting the difference

User
08/02/2018 - 03:38

So for example when you do it, on the first sheet all of the number "2"'s should be highlighed because they are all "1" on the other sheet

User
08/02/2018 - 03:38

But just make sure it does not really need to be "2" and "1"

User
08/02/2018 - 03:38

Because on the real sheet is is a lot of differnt numbers that need to be compaired

Excelchat Expert
08/02/2018 - 03:39

Okay, please hold on. I will set the solution, and tell you the steps when done

User
08/02/2018 - 03:39

Ok

Excelchat Expert
08/02/2018 - 03:44

Simply need more time to create the formula so please bear with me

User
08/02/2018 - 03:44

ok

Excelchat Expert
08/02/2018 - 03:45

Thank you :)

Excelchat Expert
08/02/2018 - 03:58

Well, as you can see I've used a helper column at col B to help us identify which number does now exist

Excelchat Expert
08/02/2018 - 03:58

So, the color coding is the next part and I'm working on it, few minutes more

User
08/02/2018 - 03:59

But when I go change the numbers on sheet 2 it doesnt change the results

Excelchat Expert
08/02/2018 - 04:01

The formula had been concentrated in checking column A of sheet1 only, to see if it exist in sheet2 with 1003

User
08/02/2018 - 04:02

But it will sometimes exist

User
08/02/2018 - 04:03

So if there is one "2" in sheet 2 then it was not be highlighin sheet 1?

User
08/02/2018 - 04:03

I need to to copare it number by number

User
08/02/2018 - 04:03

so like

Excelchat Expert
08/02/2018 - 04:03

example the no.2 at sheet1, try to put 2 in sheet2 -1003

User
08/02/2018 - 04:03

I did

User
08/02/2018 - 04:04

See what I did there

User
08/02/2018 - 04:04

I need it to look like that

User
08/02/2018 - 04:04

besides the numbers dont need to be back to back like that

User
08/02/2018 - 04:05

I need it to find the numbers that are different and hi9ghlight them\

Excelchat Expert
08/02/2018 - 04:05

Alright, it will be having another formula

Excelchat Expert
08/02/2018 - 04:05

I have to change once more

User
08/02/2018 - 04:05

There is no easy way to have excel compare two largue sets of numbers for differnces?

Excelchat Expert
08/02/2018 - 04:06

we need to consider the value of your 2rd column while comparing it, right. This makes it a bit complex

Excelchat Expert
08/02/2018 - 04:06

the 2nd column like 1003

Excelchat Expert
08/02/2018 - 04:23

Please check the sample found in response to highlighting your 2-columns

Usually, this are the steps on how to do the color coding
