How It Works

Conversion Mechanics

Plenty of older APIs, SOAP services, and enterprise systems still respond in XML, which is awkward to work with directly in modern JavaScript or Python code that expects JSON. This parses tags, nested elements, and attributes into a structured JSON object, so you can access fields normally instead of hand-rolling an XML parser.

Why It's Private

Runs Entirely In Your Browser: Files are decoded and re-encoded strictly in local memory.
No Network Requests: The converter makes no calls to any server — check your browser's DevTools Network tab to confirm.
Nothing to Sign Up For: No account, no upload, and no server-side storage of your files.
Runs On Your Hardware: Processing uses your own device's CPU via Web Workers, not a remote server.

Frequently Asked Questions on Secure XML to JSON Conversion

Attributes are included as fields on the corresponding object (typically prefixed, e.g. @attributeName) alongside the element's own content.

Repeated sibling tags with the same name are collected into a JSON array rather than overwriting each other.

Namespaced tags are parsed with their prefixes retained in the resulting keys, since stripping them could cause naming collisions.
