Excel: Ranking multiple columns of TEXT data

Situation

I have two text columns: 'Group' and 'Colours' like below and I want to use a formula to generate a 'Rank' that restarts numbering with each different group

Group - Colour - Rank
A - Red - 1
A - Red - 1
A - Blue - 2
A - Blue - 2
A - Green - 3
B - Purple - 1
B - Purple - 1
B - Yellow - 2
B - Pink - 2
C - Orange - 1
C - Blue - 1

I have tried various different formula using both SUMPRODUCT and RANK.EQ but I have not been able to produce a working formula because both columns are TEXT.

RANK.EQ fails if I pass an array (conditional evaluated) as the 2nd argument so I can't use that. It only can't use that and only appears to accept a range object - not an array of values.

I have used INDEX with no rows or columns specified to return an array to avoid entering the formula as an array CSE formula.

Question

How can I use RANK.EQ or SUMPRODUCT to produce the results in a simple formula ? Any suggestions welcomed

you can simply use COUNTIFS to rank them.

Hi,

pls try in C2

=IF(A4<>A3,-D3,0)+IF(AND(A4=A3,B4=B3),D3+0,D3+1)

ProfessorJimJam: Please provide an example as on the face of it COUNTIFS will 'count' multiple matches not 'rank' different matches - as shown in my example.

Rgonzo1971: Sorry but that only produces '1' for the first row with a unique combination of colour and group. I am also not sure what column D has to do with this - unless there is an extra step you forgot to mention :)

Corrected Formula in C2

=+IF(A2<>A1,-C1,0)+IF(AND(A2=A1,B2=B1),C1,C1+1)

Rgonzo1971: That looks good. A lesson not to get to caught up with a specific function

HOWEVER

I would still be interested if someone can advise how to get the 'Rannk.eq' function to work for my issue because this will provide a more robust solution. The two columns of text data are no GUARENTEED to be sorted and I would still rank of the colour within a group even if the colours in the group were randomly distributed e.g.

A - Red - 1
A - Blue - 2
A - Green - 3
A - Blue - 2
A - White - 4
A - Red  - 1

personally, i do not believe you can do this with Rank.eq function. i think Rgonzo formula does a great job for this purpose

Yes the formula from 'Rgonzo' is exactly what I needed !

The 'Rank.eq' function should be able to do this as it is what the function is supposed to be for !
