how to convert the given string to array in rails

Question

I have the following Strings. I want them to convert into Arrays like below in rails

"[\"Winter\", \"Summer\", \"Spring\"]" to ["Winter", "Summer", "Spring"]

"[\"IELTS\", \"GRE\", \"PTE\", \"SAT\"]" to ["IELTS", "GRE", "PTE", "SAT"]

How can i convert these

This smells like an XY problem. Where do those strings come from? — Stefan

You can do it with JSON.

require 'json'

string = "[\"Winter\", \"Summer\", \"Spring\"]"
JSON.parse(string)
=> ["Winter", "Summer", "Spring"]

just alternate solution (not safe) :

> string = "[\"Winter\", \"Summer\", \"Spring\"]"
> eval(string)
#=> ["Winter", "Summer", "Spring"]

Note: better option to parse with JSON

Please, never do things like this in production code. It may lead to a serious vulnerability.
