Set a conditional format based on a given formatted cell

Hello,

Almost everything in the title...
I am reactivating this topic few years later.
I would like to create a conditional formating entering cell format based on the format of an existing cell.
Not sure to be clear ...
As an example :
cell A1 : some format set (color, gradient, font, etc)

Then in B2 I would like to create a conditional formatting, where if condition is ok, set the format of A1.

It would mean to get all A1 cell characteritics in order to copy them in conditionnal format.

I do not know which way to start, any recommendation ?

Thanks in advance for your help

Thanks for that but not sure to see where you create a conditionnal formatting in B2.
To be more precise, I think I am stuck when trying to copy interior.gradient attribute from A1 cell format to conditionnal formatting.

Thanks Pepe.
Nothing about Gradient and ColorStops in Get.Cell function mentioned
Let's wait for another contribution.
