A JSON repair tool can correct limited, predictable formatting problems that prevent a document from being parsed as JSON. SkillHost focuses on common issues such as smart quotes and trailing commas. It does not claim to reconstruct arbitrary broken data.
A JSON Repair Tool is helpful when JSON is almost valid but contains a small, predictable formatting mistake. Common examples include smart quotation marks copied from documents and trailing commas added after the last property or array item. Repair should be treated as a convenience step, not a guarantee that arbitrary damaged data can be reconstructed.

- Click Repair or Process.
- Review the repaired JSON carefully.

Tips for using JSON Repair
Review repaired output carefully. If data is missing, brackets are incorrectly nested, or the structure is ambiguous, manual correction may be safer than automatic repair. Always run the repaired result through a JSON Validator before using it in production.
Why use a client-side JSON Repair?
SkillHost processes this JSON workflow locally in your browser using JavaScript. The core operation does not require a backend API request. This design can reduce round-trip latency and means the JSON payload does not need to be uploaded to a remote processing service for the tool operation.
Privacy and data handling
Your input remains in the browser while the tool processes it. Do not paste passwords, access tokens, private keys, production credentials, or other secrets into any online tool unless you have reviewed its security model and are comfortable doing so.

After using JSON Repair, you may also need JSON Formatter, JSON Validator, JSON Minifier, JSON Viewer, JSON Compare, or one of the JSON converters depending on your workflow.
JSON standards and developer documentation
For format details, consult RFC 8259 JSON specification. SkillHost is an independent browser-based utility and the external documentation is provided as a reference for developers.
