Frequently asked questions

Is my JSON sent to a server?

No. Formatting and validation happen entirely in your browser. We don't upload your data.

Can I minify or pretty-print?

Yes. Use the provided actions to minify compact JSON or pretty-print with indentation for readability.

How do I fix errors?

The validator shows error messages and positions so you can correct trailing commas, missing quotes, or brackets.

Do you support large JSON files?

We work in-browser and handle reasonably large inputs. Extremely large files may be slow in older devices.
