What this does
Takes a JSON document and encodes it as a single JSON string, the result of calling JSON.stringify on a string that contains JSON. You need this when a JSON payload has to travel inside another JSON field, an environment variable, a test fixture, or a line of source code.
The input is validated first, so a syntax error is reported with its line and column rather than producing a broken string.
Minify first
With Minify first on (the default) whitespace is removed before encoding, giving the shortest string. Turn it off to keep your original formatting, with line breaks escaped as \n.
To go the other way, use Parse Stringified JSON.
Example
Input:
{ "id": 7, "name": "Ada" }Result:
"{\"id\":7,\"name\":\"Ada\"}"Privacy
