How to use JSON Repair

Paste broken JSON with trailing commas, single quotes, unquoted keys, or Python-style values into the left panel and run repair.

The tool applies common repair heuristics, returns valid JSON on the right, and lists the fixes that were used.

Everything runs locally in your browser, which makes it useful for debugging invalid API payloads, logs, and copied snippets.
