How this service works
Fix broken JSON (trailing commas, single quotes, unquoted keys). Returns only valid JSON.
Output
A valid, standards-compliant JSON string with all syntax errors corrected — trailing commas removed, single quotes converted to double quotes, and unquoted keys properly quoted. The response body contains only the repaired JSON.
Example use cases
Fixing API response JSON errors
“This API response keeps throwing a parse error — can you repair it? Here's the broken JSON: {name: 'John', items: ['a', 'b',],}”
Cleaning scraped config data
“I scraped a config file but the JSON is invalid — it has trailing commas and unquoted keys. Can you fix it so I can load it into my app? Here it is: {host: 'localhost', port: 8080,}”
Repairing user-submitted JSON input
“A user submitted this JSON form data but it's malformed — single quotes and a trailing comma. Fix it so I can process it: {'email': 'user@example.com', 'subscribe': true,}”
Technical details
Endpoint
POSThttps://linked-aimed-reproduced-changing.trycloudflare.com/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a specific JSON syntax repair task — trailing commas, single quotes, or unquoted keys — and need a fast, cheap fix without spinning up a full JSON linting library. Ideal for lightweight agent pipelines that need to normalize JSON from external or user-generated sources before further processing.
Side effects
- Input is so malformed it cannot be unambiguously repaired — returns an error or best-effort guess
- Input is not JSON at all (e.g. plain text, XML) — may return error
- Extremely large payloads may time out or be rejected
- Ambiguous structure (e.g. conflicting bracket types) may produce unexpected output
