Replace characters in string with awk gsub

Hi I have a source file that looks like
HTML Code:
I want to basically change MSRP(USD) to MSRP,USD and DIST(EUR) to DIST,EUR and likewise for all i'm using the following command and able to replace "(" with , but not sure if i can use multiple replace inside gsub.

awk 'NR==1{for(i=10;i<=NF;i++){gsub(/\(/,OFS,$i);A[i]=$i}; print $A[i]}' OFS=',' FS=',' sample.txt

What output are you getting? gsub should replace every match it finds.

EDIT: Although since you're passing in one field at a time it will only ever find 1 match in this case anyway...

Whether like this ?

$ cat file

$ awk 'NR==1{gsub(/\(/,",");gsub(/\)/,x)}1' file

Need / insist on awk? If not, try
tr -s '()' ',' <file
