JSON formatting guide
JSON is a structured text format used in API responses and application settings. This formatter parses input and displays readable indentation. A successful result confirms valid JSON syntax, not whether a particular API accepts the same fields.
Practical example and limits
Try {"project":"example","active":true}. If a syntax error appears, review quotation marks, commas and brackets. Avoid publishing passwords, tokens or sensitive configuration values.
