Match function not working correctly in excel

I have two long columns I am trying to run a match on.  'A' column 800 rows the other 'b' 400

=match(A1,B:B)   is the code and then I copy it down...   the code populates correctly with the a1 changing in sequence as it should.

the first 100 or so rows perform correctly and then all of a sudden there are a ton of hits the rest of the way through a but most of them
are matching the same cell in column b that actually doesn't match.



has anyone seen  this before?

Are the values in either column [ A ], or column [ B ], results of in-cell formulae?

If so, is the Calculation Mode set to 'Manual', & a Calculation of the column(s)/worksheet is required?

Perhaps posting an attached workbook where you see this issue would help us resolve your issue.

You are omitting the Match_Type argument in the Match formula which makes it to lookup for approximate value. I am not sure if you are aware of this.

Try the following formula and see if this works for you....

=IFERROR(MATCH(A1,B:B,0),"")

Open in new window


The above formula will return the row number if it finds an exact match of A1 in col. B else it will return a blank.

If you "correct" the formula in column [C], using the third parameter "match_type" set to 0 (Exact match)...

So, cell [C1] is
=MATCH(A1,B:B,0)

Copying down column [C] shows that all the MATCH() functions fail (with #N/A).

None of the values in column [A] exist in column [ B ].

To test this, set the formula within cell [C1] as above, & copy down the column to [C13].

Next, copy the range [A1:A13] to [B14:B26].

Cell [C1] will then show 14, [C2] is 15, [C3] is 16, ... [C13] = 26.
