Using special characters causes an error when parsing JSON

I've encountered an issue while trying to parse the string below, as it contains a character ('****').

JSON.parse("{\"data\":\"value \"}")

This results in an error being thrown:

Uncaught SyntaxError: Unexpected token in JSON at position 15

How can I resolve this problem?

Note: I am looking for a generic solution as I need to skip all special characters that may appear dynamically. Is there a way to achieve this?

There appears to be special characters present in the excel file. To resolve this issue, you can use the following script:

<script type='text/javascript'>
        window.onload = function () {
            var str ='{\"data\":\"value \ \"}'.replace(/\\n/g, "\\n")
               .replace(/\\'/g, "\\'")
               .replace(/\\"/g, '\\"')
               .replace(/\\&/g, "\\&")
               .replace(/\\r/g, "\\r")
               .replace(/\\t/g, "\\t")
               .replace(/\\b/g, "\\b")
               .replace(/\\f/g, "\\f");
            var d = JSON.parse(str);
            alert(d.data);
        }
    </script>
