# Jsonyfier

> Free, no-signup JSON tools: format, validate, minify, escape.
> Browser-side processing — your JSON is never uploaded.

Jsonyfier is operated by Dynamic Foundries, a French SASU registered
in Paris (RCS Paris 102 801 206). Hosted in OVH Gravelines, France.

## What it does

- **Format / prettify** — pretty-print JSON with configurable indent
- **Validate** — check if the JSON is well-formed and explain errors
- **Minify** — strip whitespace for production payloads
- **Escape / unescape** — JSON-escape strings for embedding inside
  other JSON
- **Tree view** — collapsible viewer for large objects

All processing happens in your browser. Your JSON is never uploaded
to our servers (or to any other server).

## Defensible facts

- Free, no signup, no ads
