microsoft excel – Highlight all the cells if the keyword in the cell matches to any value of a list

For one of my excel sheet, it is required to highlight the cells that has specific keyword in it.
To solve this, i have created a list called my_list which contains value1, value2 & value3.

I have used below formula for highlighting the column D

=OR(ISNUMBER(SEARCH(my_list,D1)))

It’s working fine for the column D

I want this to be extended for all the columns in the excel sheet

its very tedious to write the above formula for all the columns

is there any change that can be made to above formula which works for all the columns/entire excel sheet?

I tried with below which didn’t help

=OR(ISNUMBER(SEARCH(my_list,my_excel)))

where my_excel is the selection to all cells in the excel sheet

can you please help with me this?
