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.
