JSON.parse incorrect string format

i have this string:

"{\'Ovcount\':\'0\',\'S1\':\'LU\',\'S2\':\'NewClientOrMove\',\'memoToDisplay\':\'LU -- New Client or Move\"}"; 

and i want it to become like this:

'{"Ovcount":"0","S1":"LU","S2":"NewClientOrMove","memoToDisplay":"LU -- New Client or Move"}'

I tried with stringify and replace and i ended up with

"{'Ovcount':'0','S1':'LU','S2':'NewClientOrMove','memoToDisplay':'LU -- New Client or Move"}"

And from here i wanted to replace the single quotation marks ' with double quotation marks " but when i did, in beginning and ending of the string appeared an extra "

" "{"Ovcount":"0","S1":"LU","S2":"NewClientOrMove","memoToDisplay":"LU -- New Client or Move"} ""

Any tips on how to get the correct format?

Answer

var result = "{'Ovcount':'0','S1':'LU','S2':'NewClientOrMove','memoToDisplay':'LU -- New Client or Move"}"
  .replaceAll("'", '"')
  .replaceAll('\', '');
console.log(result);

this got me what you wanted, it replaces all the single quotes with double quotes, then it removes any back slashes

the result is

‘{“Ovcount”:”0″,”S1″:”LU”,”S2″:”NewClientOrMove”,”memoToDisplay”:”LU — New Client or Move”}’
