Pattern detection can produce false positives and cannot prove a payload is safe. Findings are explainable so you can review them before export.

QUESTIONS, ANSWERED

Does jsontools.me upload my JSON?

No. The document is parsed and processed by json-buf inside a dedicated WebAssembly worker on your device.

Does it work offline?

Yes. After the application shell and engine have loaded once, the installable PWA keeps the tools available without a network connection.
