I have a spreadsheet with 2 lists of data, each list contains a number of
columns, the 2 lists are not equal in length, list 1 is about 2,600 rows and
list 2 is about 50,000 rows

The left most column in each list contains part numbers, these are unique
values that sometimes contain alpha characters and sometimes not.

The first list is a 'finished' list that I wish to use for display, but the
second list has a column that contains a statistic that I have been asked to
incorporate into the finished list.

The second list also has most of the part numbers present in the first list
(about 94%), so I didn't think the task would be too hard, a relatively
simple formula should do the trick - but my formula has returned results that
I do not understand.

My formula is thus:

"=IF(COUNTIF($Q$2:$Q49959,A2636)<0,OFFSET($Q$1,MA TCH(A2636,$Q$2:$Q$49959,1),4,1,1),0)"

Now the formula works fine with the exception of the MATCH function, the
cell A2636 has the part number 1672312 with no spaces before or after.

The part number 1672312 exists in the second list in cell Q1557, again with
no spaces before or after and as can be seen by the formula, the value I want
is in the fifth column of the list.

The MATCH function seems to want to match to a part number 167-2222 which is
located in the cell Q7638.

I tried altering the format of the part number columns to text, but it made
no difference. I also tried altering the MATCH_TYPE argument of the function
from 1 to 0 to force an exact match, the formula then returns an error.

Now I do not consider myself an Excel novice and I know that this task would
be easily accomplished with a little VBA, but that's not the point. I have
read the help file again to make sure that I was using the MATCH function
correctly. I tried alternatives like VLOOKUP to see what it matched to, again
it matches to the same incorrect cell.

I suspect formatting of the part number columns somehow, but I don't know
how - the part number columns contain absolute values, no underlying
formula's, no linked cells or anything like that. Using the Formula Evaluate
tool shows me that the cell A2636 evaluates to the correct part number, but
from there is goes south.

Anyone have any ideas?

What error do you get when you change the Match Type argument?

You will need to have the match-type parameter set to 0 to look for an
exact match - what error does this return?

OFFSET($Q$1,MATCH(A2636,$Q$2:$Q$49959,1),4,1,1),0 )

Your MATCH call, using 3rd argument 1, assumes Q2:Q49959 is sorted in
what Excel considers ascending order, meaning numbers first in
ascending order, then mixed numerals and letters in text order. Unless
you've sorted your second table on its first column, I'd bet the
problem is that this column isn't sorted as Excel needs it.

Also, if A2636 contained the NUMBER 123456, that would NOT match the
text "123456" in Q2:Q49959 and vice versa. You should ensure that all
cells in Q2:Q49959 *AND* cell A2636 (or, maybe, all cells in the first
column of your first table) are text, and then sort the second table
into ascending order on its first column.

Now the formula works fine with the exception of the MATCH function,
the cell A2636 has the part number 1672312 with no spaces before or
after.

The part number 1672312 exists in the second list in cell Q1557,
again with no spaces before or after and as can be seen by the
formula, the value I want is in the fifth column of the list.

If the formula

=ISNUMBER(A2636)=ISNUMBER(Q1557)

returns FALSE then one of these cells is numeric, the other text, and
Excel will *NOT* consider them equal.

The MATCH function seems to want to match to a part number 167-2222
which is located in the cell Q7638.

This would tend to imply that Q1557 is numeric and A2636 is text.

I tried altering the format of the part number columns to text, but
it made no difference.

Of course not. Number formatting doesn't, never has and never will
affect the value a cell contains. If you have a numeric value in a
cell, the ONLY way to change it to text is to ENTER text. That can be
achieved by changing the number format to Text then re-entering the
cell, and the re-entry is NECESSARY.

I also tried altering the MATCH_TYPE argument of the function
from 1 to 0 to force an exact match, the formula then returns an
error.
....

As it should. Exact matching also REQUIRES that value sought (first
argument) and value found in the lookup range (second argument) are
the same type, either both text or both numbers. Excel will NEVER
match number against text or vice versa.

If you try a simple comparison of the two cells that you believe are
identical and should return a positive result, what do you get? eg Assuming
you had two values in say A1 and F3, then a simple =A1=F3 would either
return TRUE or FALSE. What does thsi give on your two values?

This means that there is no exact match. Are you sure that the
formatting is the same for the lookup-value and the lookup-range?
Could one be a number and the other be text? You say that there are
leading or trailing spaces - have you applied TRIM to get rid of any
that might be lurking? Could you possibly have any non-breaking space
characters (char 160)?

Basically, you need to check the data thoroughly, and the data types
must be the same.

Hope this helps.

It may have no spaces before or after, but there may still be differences between text and number.
Test that with the ISNUMBER() or ISTEXT() functions, and compare the length of the items with the LENGTH() function for the

After a little more research I have discovered that the part numbers that
contain mixed alpha and numeric values match exactly, the only ones that fail
are the those that are all numeric.

I was apparently supposed to have had this out yesterday - oops, so I have
written a sub that has done the trick

In response to your question Ken, the comparison produces a TRUE result.

Okay, that's interesting - I've never struck non-breaking spaces before.
Definately something to look out for, thanks.
