How to search in excel using regular expressions?

Question

excel

Greetings
In the excel file, there are cells with numbers written with a hyphen:

1-1
22-33
500-100
30-120

Is it possible to search and highlight such cells in excel itself? If possible, please tell me how.

If the task is set exactly as voiced, then regular expressions are not needed for this. Read about conditional formatting in Excel.
