Question 1

Is my JSON sent to a server?

Accepted Answer

No. JSON App is 100% client-side. All validating, formatting, sorting, converting, and downloading happens in your browser. Nothing is uploaded, stored, logged, or saved anywhere.

Question 2

What is the difference between Beautify and Minify?

Accepted Answer

Beautify pretty-prints your JSON with indentation and line breaks so it is easy to read. Minify strips all unnecessary whitespace to produce the smallest possible single-line JSON.

Question 3

Which formats can I convert JSON to?

Accepted Answer

XML, CSV, YAML, TOML, and HTML. Each conversion can be copied to the clipboard or downloaded with the correct file extension.

Question 4

Can it fix invalid or broken JSON?

Accepted Answer

Yes. The Fix / Optimize tool removes comments, converts single quotes to double quotes, quotes unquoted keys, removes trailing commas, and converts Python/JS literals so the JSON complies with the official JSON specification.

Question 5

Does JSON App work offline?

Accepted Answer

Yes. Once the page has loaded you can disconnect from the internet and every feature keeps working, because all processing runs locally.
