Reges expression problem

Hello ,

I am not sure how to use Regex expression

First example :

street name 34 (56)

street name 56 ( 44 )

street name 55(70) or street name 55( 70 )

I would like to extract the number between parentheses and add - before the number

so it should be street name 34 - 56

second example :

street name 56 (text)

street name 40 ( text )

street name 10(text)

street name 40( text )

i would like to extract the text between parentheses and create it in new column

third example :

street name 20 ( GdR 20 )

street name 22 (23-50)

I would like to extract it and add - before the value in parentheses

So it should be street name 20 - GdR 20

thanks in advance
