I have used a similar technique using conditional formatting to identify when lists change. Our Production Scheduling Program gives a readout like this:-
Dept M/c Tool Job No
A A1 T1 J1
A A1 T1 J2
A A1 T2 J3
A A2 T2 J4
A A2 T3 J5
A A2 T3 J6
A A2 T4 J7
A A2 T5 J8
A A2 T6 J9
B B1 T7 J10
B B1 T7 J11
B B1 T7 J12
B B1 T8 J13
B B2 T9 J14
B B2 T10 J15
B B2 T10 J16
B B2 T10 J17
B B2 T10 J18
If you add 2 conditional formats to each cell:-
=A2=A1 - font colour equals white &
=A2A1 - add a line to the top of the cell it comes out like this:-
Dept M/c Tool Job No
A A1 T1 J1
J2
T2 J3
J4
A2 T3 J5
J6
T4 J7
T5 J8
T6 J9
B B1 T7 J10
J11
J12
T8 J13
B2 T9 J14
T10 J15
J16
J17
J18
With the proper spread sheet with the horizontal lines drawn this is much easier to read
Hi Chandoo
Sorry about the formatting of the above post.
I am new at this commenting game & dont know how to make the formatting come out correct
@Peter H: Welcome to PHD and commenting. 🙂 I like your idea. When I get sometime I will create a screenshot of this and post it here so that other readers will know how it would look.
Also, you dont need 2 conditional formats. You can set the cell font color to white for all in one stroke and then use conditional formatting to turn the color to black when a2 not equal to a1.

Hi Chris,
I had a similar requirement and I have achieved this using a simple formula...
=IF(A1A2,1,B1+1)
and apply this formula for all rows in B column... hope this solves your issue.
Thanks Charan!! I was looking for the similar for formula. Even though very simple, in crunch time, nothing will work. Thanks Charan for great help
Great!
Hello! I would like more help with this formula, please. I know it is exactly what I am looking for but I am having trouble on how to apply it. I have a list of schools (Column A) that have corresponding project numbers (Column B), and get a different phase number (Column C) each time a project comes in. It looks just like the data above but I can't get it to sequence correctly.
