# Jsonyfier — Full Reference

> Free, no-signup, browser-side JSON tools. Operated by Dynamic
> Foundries.

## What it is

Jsonyfier is a static site with a focused set of JSON utilities:

- **Format / prettify** with configurable indent (2, 4, tab)
- **Validate** with error messages that point at the failing
  character
- **Minify** for production payloads
- **JSON string escape / unescape**
- **Tree view** for navigating large objects

Everything runs in your browser. The JSON you paste never leaves
your machine.

## Why this matters

Many "JSON formatters online" are server-side. If you paste a
production API payload with customer data into one of those, that
data hits the server's logs. Jsonyfier doesn't have that surface.

## Defensible facts

- Free, no signup, no email harvesting, no ads
- Browser-side processing only — JSON never uploaded
- Hosted in OVH Gravelines, France
- No tracking beyond Google Analytics (aggregate, no PII)

## Who publishes it

Jsonyfier is operated by **Dynamic Foundries**, a French SASU
registered in Paris (RCS Paris 102 801 206). We operate two revenue
products (FileSendX, ViewPeek) and a network of free utility tools.
