Questions
Frequently asked
Is my work saved?
No. Nothing is persisted server-side or client-side. Use Download to keep a copy.
Is my data uploaded anywhere?
No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
Does it work offline?
Yes. JSONWorks is installable as a progressive web app and caches itself on first visit, so every tool keeps working without a connection.
