Is this JSON to TS safe for sensitive data & credentials?

Yes, 100%. All processing runs client-side in your local browser memory. No text, tokens, payloads, or logs are ever transmitted to any remote server or analytics engine.

Can I use JSON to TS offline without internet?

Yes. Because this tool runs strictly on client-side JavaScript with zero external API calls, once the web application is loaded in your browser it will continue working offline.

How does URL state sharing work?
