Identify Rows with Same Values in 2 Different Columns

Question

I have a data set of roughly 405,000 rows and 23 columns. I need the records where the value in column "D" is the same as the value in column "H" for that row.

So for

A  B  C  D  E  F  G  H 
13 8 21 ok  3  S  - of
51 7 22 no  3  A  k no
24 3 23 by  3  S  * we
24 4 24 we  3  S  ! ok
24 9 25 by  3  S  @ we
75 2 26 ok  3  S  9 ok

etc...

I'd get back the 2nd row, the 6th row, etc...

A  B  C  D  E  F  G  H 
51 7 22 no  3  A  k no
75 2 26 ok  3  S  9 ok

Based on other posts like: Formula to find matching row value based on cells in multiple columns I tried using a Pivot Table, but it complains I can't put either of my two columns in the "Columns" area because there is too much data. With both columns in the "Rows" area, I get a relationship of D to H, but I can't then find a way to filter on only those where D = H.

I've also looked into countifs(), vlookup, and index / match functions, but I can't figure this out. Help please.

Answer 1

I would do a simple "IF()" formula in a new column.

For your example add a new column I and use the following formula in the first data row (I2):

=IF(D2=H2,"Yes","No")

Fill down to the end of the data.

Then using Excel filters or countif you can check the number of "Yes" vs "No" in your data.
