Try this here, there are two reg-ex. gsub will do a global substitution.

I did it with the help of https://regex101.com/

str = '{"user_id"=> "row[:user_id]",
 "name" => "row[:name]",
 "address" => "row[:address]"
}'

re = /\"row\[:/m
subst = 'row[:'
result1 = str.gsub(re, subst)

re = /]"/m
subst = ']'
result2 = result1.gsub(re, subst)

# Print the result of the substitution
puts result2
