How this service works
Fix broken JSON (trailing commas, single quotes, unquoted keys). Returns only valid JSON.
Output
Returns a valid, fully-parsed JSON object with all syntax errors corrected — trailing commas removed, single quotes replaced with double quotes, and unquoted keys properly quoted — ready to parse without further modification.
Example use cases
Fixing LLM-generated JSON output
“The JSON that came back from my language model has single quotes and a trailing comma — can you repair it so it's valid and I can parse it properly?”
Sanitizing user-submitted config data
“A user pasted this config into our form and it has unquoted keys and trailing commas: {name: 'server1', port: 8080,} — fix it into valid JSON for me.”
Repairing hand-edited JSON files
“I manually edited a JSON file and now it won't parse — it has some single quotes and a trailing comma on the last field. Can you fix it and give me back valid JSON?”
Technical details
Endpoint
POSThttps://biz-integral-pull-earrings.trycloudflare.com/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have JSON that is syntactically invalid due to common human or LLM-introduced errors like trailing commas, single-quoted strings, or unquoted keys, and you need a fast, cheap ($0.005/call) programmatic fix without writing custom parsing logic. Avoid if the JSON is structurally corrupted beyond simple syntax issues.
Side effects
- JSON is too structurally broken to repair (e.g. mismatched brackets) — may return an error or best-effort partial fix
- Input is not JSON at all — endpoint may fail or return unexpected output
- Ambiguous syntax may be repaired incorrectly, changing intended semantics
- Service unavailable if Cloudflare Tunnel goes offline (ephemeral URL)
