extract text form text string( extract 5 charactors in front of all left parenthese)

Dear All,

I need to extract text form text string. there are multiple parentheses in the text string.
There are multiple parentheses in the text string.
My goal is to extract 5 charactors in front of all left parenthese.



First I tried

=TRIM(MID(SUBSTITUTE(SUBSTITUTE("("&$A2,"(",")"),")",REPT(" ",LEN($A2))),2*LEN($A2)*(COLUMNS($A:A)),LEN($A2)))

which works well to extract all the context inside the parentheses.

Then I tried

=MID(A2,SEARCH("(",A2)-5,SEARCH(")",A2)-SEARCH("(",A2)+7)

which works well to extract the 5 charactors in front of "(" but it only works for the first "(", not all of them in the test string.

I don't know how to combine these two to achieve my goal.

Please kindly help me out here..

With My Best Regards,

PS. If anyone could explain the first formula for me that would be great.
I am thinking if I could just edit a little based on the first formula to achieve my goal here?

Any help would be greatly appreciated.

Many thanks,
