Remove first level of escape in json String (Java)

I have a String like this:

private String jsonString = "{\"test\":\"value \\\"ciao\\\"  \"}"

At runtime this should be: {"test":"value \"ciao\" "}

Now I want to remove the only the first level of escape and leaving the nested escape.

The result should be:
{"test":"value "ciao" "}

How can I do this? Is it possible with methods like replace() or replaceAll()?

    You can use replaceAll() like this:

    public class Main {
    public static void main(String[] args) {
        String jsonString = "{\"test\":\"value \\\"ciao\\\"  \"}";

        String unescapedString = jsonString.replaceAll("\\\\", "\\").replaceAll("\\\"", """);

        System.out.println(unescapedString);
    }
}

    You can use the String#translateEscapes method.

    String s = "{\"test\":\"value \\\"ciao\\\"  \"}";
s = s.translateEscapes();

    Output

    {"test":"value "ciao"  "}
