What Is the JavaScript / JSON Converter?

The JavaScript / JSON Converter is a free online developer tool that allows you to easily convert between JavaScript objects and JSON, with full control over formatting and indentation.

The tool provides two modes: JavaScript to JSON and JSON to JavaScript.

JavaScript to JSON

This mode converts a JavaScript object into JSON format. Enter a valid JavaScript object (quotes around keys are optional), choose your preferred indentation level, and click the convert button.

Example input (JavaScript object):
{ a: 1, b: 2 }

Example output (JSON):
{ "a": 1, "b": 2 }

JSON to JavaScript

This mode converts JSON into a JavaScript object. It is the reverse of the previous example and typically removes quotes from keys when they are valid JavaScript identifiers.

Example input (JSON):
{ "a": 1, "b": 2 }

Example output (JavaScript object):
{ a: 1, b: 2 }
