Frequently Asked Questions

How is this different from the JSON Validator?

The validator gives you a pass/fail plus structural stats. This tool goes further on failure — it recognizes the most common error patterns (trailing commas, single quotes, unquoted keys, comments) and explains what likely went wrong in plain language.

Can it fix my JSON automatically?

No — it explains the problem so you can fix it yourself, since silently "fixing" JSON risks changing your intended data.

What if my error isn't one of the common patterns?

You still get the raw line and column from the parser, even when the tool can't offer a specific explanation.

Is my JSON uploaded anywhere?

No — parsing happens entirely in your browser via the native JSON.parse.
