About MUNEX.IN JSON Tools

MUNEX.IN is a free developer tool for working with JSON: format and validate it, repair broken input, explore it as a collapsible tree or an interactive flowchart, and convert it to YAML, CSV, XML or TypeScript interfaces.

Private by architecture

Every operation runs as JavaScript in your browser. There is no upload endpoint, no processing server and no database — which means API keys, customer data and production payloads you paste here stay on your machine. You can verify this in your browser's network tab: after the page loads, no requests carry your data anywhere.

Built for speed

The flowchart view uses a hand-written SVG layout engine instead of a heavyweight graph library, so even large documents render instantly and the page stays light. Your input is saved to your browser's local storage between visits — clear it any time with the Clear button.

Who makes it
