i have 2 columns where i need to extract matched/unmatched values
from....

i've tried a few different methods but none seem to be working the way
i want it to because of the duplicate values (the problem is that these
are "legitimate" duplicates)....which is making me question whether it's
even possible?!?!?!

example - if value in column A exists in column B, then remove from
both columns

A B
1 0
1 1
1 2
2 2
3 3
3 3

desired result:

A B
1 0
1 2


i've tried an excel add-on called DigDB....however, it will give me
"matched" results regardless of how many there are (i.e. it will tell
me all the values = 1 and values = 2 are matched eventhough there are
more in one column than the other)...

i tried vlookup but again, the dups create a problem for me...(unless
someone can provide me with a multiple vlookup statement for
this?)....

pls help...i don't want to resort to doing this in multiple layers!!!!
:(

Maybe you can use a formula:

Say in C2 (headers in row 1??)
=if(a2=b2,"same","different")

Then drag down the column

Then select column C and apply
data|filter|autofilter

You can choose to view only the Different's--or choose to show the Same's. Then
you can delete those visible rows and then remove the filter (data|Filter|show
all) to see the remaining.

c1: if(a1=b1,a1,"")
d1: if(a1=b1,b1,"")

copy down.

This will leave blanks where the dupes are, but there's lots of code
posted here to help you eliminate the blanks.

the scope of my issue.....please refer to this modified example:

A B
1 0
1 1
1 2
2 2
2 2
3 2
4 2
5 3
5 4
6 4
6 5

desired result:

A B
1 0

6 4

my apologies for overlooking this...pls let me know if this example is
not clear....thx again!

I don't see a pattern there.

hmmmm....let me try that again.....

A B
1 0
1 1
1 2
2 2
2 2
3 2
4 2
5 3
5 4
6 4
6 5

in A the value of "1" is listed 3 times, whereas in B it is listed
once....so i want to remove only 1 of those values from A and the one
in B....

for the value of "2" i want to remove both from A and only 2 from
B.....etc....the "0" stays in B because it doesn't appear in A....:

A B
1 0
1 2
5 2
6 2
6 4

does this explain it a little better?

This seemed to work ok for me.

I put the test data in A1:Axxx and B1:Byyy

I put this in C1 and copied down:
=IF(A1="",NA(),IF(COUNTIF($A$1:$A1,A1)<=COUNTIF(B: B,A1),NA(),A1))

and this in D1 and copied down:
=IF(B1="",NA(),IF(COUNTIF($B$1:$B1,B1)<=COUNTIF(A: A,B1),NA(),B1))

Now I'm left something that looks like this:
#N/A 0
1 #N/A
1 #N/A
#N/A #N/A
#N/A 2
#N/A 2
#N/A 2
#N/A #N/A
5 #N/A
6 4
6 #N/A

The numbers match your numbers--but those #n/a's are ugly.

I selected C:D
edit|copy
edit|paste special|values

Now my formulas are gone.

With C:D still selected
edit|goto|special|constants|Errors (only errors, uncheck all the other options!)

Notice that only the errors are still selected.
Edit|Delete|Shift cells up.

I was left with:
1 0
1 2
5 2
6 2
6 4


And that's very close to what you got!
