Conditional format

New Contributor


Having the hardest times setting up a conditional format were i need to highlight a duplicated date with the client first name. for instance Aaron had two services the same day 5/3/21 but when i do a conditional format Adrienne is highlighted as well but she does not have a duplicate service for the same day. i need to find a way to highlight clients that receive multiple services on the same day.

@JulMir0689 Hi there,

I made slight changes in your excel file, solved the issue and attached to this email.

I changed date to day format. Added two repetitive rows to be sure that the conditional formatting works well.

To solve this issue, I used Countifs and If functions.

Have a good day.


=IF(COUNTIFS($A$2:$A$14,A2,$C$2:$C$14,C2)>1,TRUE, FALSE)



If you like this solution, please highlight:))

i like it but it would be helpful if it would be possible to have a number rather than true or false for instance if there are two services for the one day have a number 2 and if three services in the same day a number 3 is that possible?@Ilgar_Zarbaliyev 


Conditional Formatting is working on basis of Boolean Logic (True or False Values).
Actually, if you take if function from my formula, it will give you numbers.


I continue to have the hardest time figuring this out, can you help me again?

I need to find a way to conditional format the same person with multiple dates that are the same (cell 10,11 and 12) then count the duration (Column F 120 minutes) and place a #1 in AH and since its more than one service cell AK needs a 1 in it Aswell as a 1 in cells M because its a D22 AA because its a D7 and AB because its a D3

but this is definitely to complicated for me, i am not even sure if it is possible.

do you think you can help me?
