That's simply invalid JSON, see the rules for strings on json. There is no \x escape in JSON. The \xbaB should be a unicode escape, \u0baB (note that there must be exactly four hex digits):

var mystring ='{"Customers":[{"CustomerCity":"Zaragoza","CustomerFName":"Ana","CustomerAddress":"C/ El Temple, 9 2\\u0baB","CustomerCountry":"es"}]}';

var obj = JSON.parse(mystring);
console.log(obj);

You could try to pre-process the string:

mystring = mystring.replace(/\\x([0-9a-f]{1,4})/gi, function(m, c0) {
    return "\\u" + ("0000" + c0).slice(-4);
});

var mystring ='{"Customers":[{"CustomerCity":"Zaragoza","CustomerFName":"Ana","CustomerAddress":"C/ El Temple, 9 2\\xbaB","CustomerCountry":"es"}]}';

// Fixing it
mystring = mystring.replace(/\\x([0-9a-f]{1,4})/gi, function(m, c0) {
    return "\\u" + ("0000" + c0).slice(-4);
});

var obj = JSON.parse(mystring);
console.log(obj);

...but really, it would be much better to fix the source of the JSON so it produces valid JSON, and the above is a very naïve fix.
