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

I have a numeric identifier in column A with a corresponding numeric value (Let's call it Z) X columns below it. There are varying duplicated cells of the identifier before Z I also have a numeric value (Y) in Column B that I am trying to verify is the same value as Z. Is there a way to scan down Column A, identify Z, and match it to Y?

Hello, I understand that you are trying to lookup values. In order to have a better understanding of your requirement, can you share a sample data using the document to the right?
User 08/08/2018 - 03:24
sure one moment
User 08/08/2018 - 03:25
Column A has a 16 digit identification number, that is duped a random number of times, with a corresponding dollar value below however many dupes it has
User 08/08/2018 - 03:26
then I have VLOOKUP'd a corresponding value to that number from a different source
User 08/08/2018 - 03:27
I need to crash the two to make sure the two dollar values match and identify the 16 digit id numbers where they dont
Excelchat Expert 08/08/2018 - 03:27
Can you recreate the different source as well so I'll be able to understand it better. So far it's not making any sense yet.
Excelchat Expert 08/08/2018 - 03:29
Are you still with me?
User 08/08/2018 - 03:30
I cannot recreate it. Think of the 16 digit number as an "Account Number" and anything smaller than that as a payment on that account
Excelchat Expert 08/08/2018 - 03:30
So in this case, A1 to A3 is the account number and A4 is the payment?
User 08/08/2018 - 03:30
Column A is payment data from an outside system sent to me that I have not manipulated. Column B is payment into from an internal system that I have pulled based off of the same account number
User 08/08/2018 - 03:30
yes
Excelchat Expert 08/08/2018 - 03:31
Okay, and what do you need help with?
User 08/08/2018 - 03:31
A4 is the external record of payment, B3 is the internal record
User 08/08/2018 - 03:31
I need to reconcile the two
Excelchat Expert 08/08/2018 - 03:31
Can you give an example where they don't match?
User 08/08/2018 - 03:31
That's what I can't find
User 08/08/2018 - 03:32
The problem is that there are not always the same number of duplicated account numbers in column A
User 08/08/2018 - 03:32
Hold on I can show you
Excelchat Expert 08/08/2018 - 03:32
I just need to see how a non match will look like.
Excelchat Expert 08/08/2018 - 03:32
Otherwise, I won't even know what to look for.
User 08/08/2018 - 03:33
it follows this format
Excelchat Expert 08/08/2018 - 03:34
So you only need to match the last payment for that particular account number and the payment that is under the account number?
User 08/08/2018 - 03:34
oh wait I displayed that wrong
User 08/08/2018 - 03:36
actually yes you are correct
User 08/08/2018 - 03:36
yes I only need to match the last payment
Excelchat Expert 08/08/2018 - 03:37

thank you
Excelchat Expert 08/08/2018 - 03:37
Please extend the session when prompted.
Excelchat Expert 08/08/2018 - 03:38
16 digits or 15?
User 08/08/2018 - 03:38
16
Excelchat Expert 08/08/2018 - 03:39
Okay, the formula in column C should help identify those that don't match.
Excelchat Expert 08/08/2018 - 03:39
It first checks if the value in column A is 16 digits long, if it is not then it compares the value in A to the value in B but 1 row less.
Excelchat Expert 08/08/2018 - 03:40
You'll see that it'll return FALSE if they don't match.
User 08/08/2018 - 03:40
ahhhhhh
User 08/08/2018 - 03:40
genius
User 08/08/2018 - 03:40
