About Our JSON Escape / Unescape Tool

Our tool provides a simple, fast, and reliable way to handle JSON string escaping and unescaping. Whether you're a developer preparing a string to be embedded within a JSON object or trying to read a string that has been extracted from one, this utility is designed to make your life easier. All processing is done securely on your local machine—your data never leaves your browser.

What is JSON Escaping?

JSON escaping is the process of converting special characters within a string into their "escaped" format. This is necessary when you need to include a string that contains special characters (like double quotes, backslashes, or newlines) as a value within a JSON object. The escaping process ensures that the receiving application correctly interprets the string without breaking the JSON structure.

For example, the double quote character " must be escaped as \" so it is treated as part of the string, not as the end of the string value.

Why Do We Need to Escape and Unescape JSON?

The primary use case is embedding complex data, such as another JSON object or HTML code, as a string field inside a larger JSON object.

Example: Imagine you want to store this JSON object: {"message": "Hello, world!"} as a string value inside another JSON.

You can't just write:

{"data": "{"message": "Hello, world!"}"}

This is invalid JSON. You must escape the inner string first:

{"data": "{\"message\":\"Hello, world!\"}"}

Conversely, when you retrieve this data value, you get the escaped string {\"message\":\"Hello, world!\"}. To use it as a JSON object again, you need to unescape it back to its original form.
