How can I remove escape sequences from JSON.stringify so that it's human-readable?

Question

When I call JSON.stringify() on a complex object in JavaScript, it produces a string with lots of escape sequences (\\\", \\\\\", etc.).

How can I make it create a h

Answer 1

You can use the replacer. The second parameter provided by JSON.stringify.Replacer could be a function or array.

In your case we can create a function which replaces all the special characters with a blank space.The below example replaces the whitespaces and underscores.

function replacer(key, value) {
  return value.replace(/[^\w\s]/gi, '');
}

var foo = {"a":"1","b":2};
var jsonString = JSON.stringify(foo, replacer);

If you simply want to replace the one special character, use:

JSON.stringify({ a: 1, b: 2 }, null, '\t');

For more information on replacer, check the MDN page JSON.stringify().
