I want to remove some special character from json without parsing the json into object.

Parsing would result into error that is why i wanted to do without json.parse().

below is my json:

{
    "id":324,
    "name":"first",
    "body":{
        "sbody": "<p>\\\The New Stroy\\\</p>"
    }
}

desired output:

{
    "id":324,
    "name":"first",
    "body":{
        "sbody": "<p> The New Stroy </p>"
    }
}

• 1 Given the syntax, what you appear to have is an object, not JSON. Therefore any use of JSON.parse is irrelevant. – Rory McCrossan Commented Oct 19, 2018 at 10:28
• What are those special character? Just slashes? Repeated slashes? Invalid escape sequences? – Federico klez Culloca Commented Oct 19, 2018 at 10:28
• Why would you not want to parse it? To ensure you know you're looking at a string you'll end up with a parser. – Richard Commented Oct 19, 2018 at 10:28

Looks like your input is a string and the error you are getting is when using JSON.parse.

Try this

var response = '{"sbody": "<p>\\\The New Stroy\\\</p>"}';
response = response.replace(/\\/g, "");
var obj = JSON.parse(response);

console.log(obj);

You need to run .replace on your string:

var string = '{"id":324,"name":"first","body":{"sbody":"<p>\\\The New Stroy\\\</p>"}}';

string = string.replace(/\\/g,'');

console.log(string);

//{"id":324,"name":"first","body":{"sbody":"<p>The New Stroy</p>"}}

The reason the pattern is /\\/ is because \ is used to escape characters. With a single \ we end up escaping the /. What we need to do here is escape the escape character to turn it into a literal string character: \\.

The g after the pattern means to search for the pattern "globally" in the string, so we replace all instances of it.

var obj = {
    "id":324,
    "name":"first",
    "body":{
        "sbody": "<p>\\\The New Stroy\\\</p>"
    }
}

// Convert object to string
var str = JSON.stringify(obj);

// Remove \ from the string
var convertedStr= str.replace(/\\/g,'');

// Convert updated string back to object
var newObj = JSON.parse(convertedStr);
