checking for duplicates in two data bases

I read your instructions on checking for duplicates but what if the rows are not aligned and the duplicate name is on the 4th row in 1 list and the 5th row in the other list. Because they are not aligned they appear as not a match. Is there just a way to see the names (or another data element ie. emails) that are not the same in both list?

I don't know what instruction you are referencing and how your "data bases" look like.


But here a simple solution.

B2=XLOOKUP(A2,Table 2::A,Table 2::A,"Not in list",0,1)


XLOOKUP will search for a name and if it will not find the name it will return "Not in list"

Now you know what name from table 1 is not included in table 2

For table 2 you would have to do the same thing.


Based on your region the , or the ; will be used to separate the different sections of a formula. If you write one thousand as 1,000.00 then the , is used as your formula separator. If you write one thousand as 1.000,00 then the ; is used as your formula separator.


Hope this will solve your question, please let me know if this worked for you or if something in unclear.
