Formatted JSON
Illustrative view
Input is parsed before formatted output is produced.
The formatter first parses strict JSON. When syntax is invalid, it attempts a safe repair for common problems such as trailing commas, single quotes, comments, unquoted keys, missing delimiters, and JSON wrapped in Markdown fences.
Every automatic repair is shown for review before the formatted or minified result. The tool never evaluates input as JavaScript, and it reports an error when ambiguous content cannot be repaired safely.
