What does JSON string escaping do?

JSON string escaping converts special characters like quotes ("), newlines ( ), backslashes (\), and tabs ( ) into valid JSON escape sequences so they can be safely stored or transmitted without breaking JSON syntax.

Why do WhatsApp Cloud API payloads require escaped strings?

When sending WhatsApp messages containing quotes, line breaks, or code snippets, the message body must be properly escaped inside the JSON payload to prevent 400 Bad Request syntax errors from Meta's Graph API.

Is my JSON data processed securely?

Yes! All escaping, unescaping, formatting, and minifying happens 100% client-side in your web browser. Your API keys, tokens, and payloads are never sent to any server.

Got Questions?

JSON Tool FAQ

Frequently asked questions about escaping, unescaping, and formatting JSON strings.

JSON strings are enclosed in double quotes ("). If your string content contains quotes, newlines, or backslashes without escaping, JSON parsers cannot determine where the string begins and ends, throwing syntax parsing errors.

Inside the body property of your WhatsApp Cloud API JSON payload, represent line breaks using the escape sequence \n (for example: "body": "Line 1\nLine 2\nLine 3").
