XML to JSON

Parse XML with the browser's DOMParser and emit structured JSON: attributes become @keys, repeated siblings become arrays.

About this tool

Attributes become at-prefixed keys, repeated siblings become arrays, and text nodes stay as strings — parsed by the browser own XML parser with errors reported verbatim.

How to use the XML to JSON tool

  1. Paste the XML. Well-formed documents only.
  2. Convert. The tree becomes nested JSON.
  3. Copy the result. Formatted with two-space indentation.

Supported formats

Input

  • Plain text or file input

Output

  • Converted or analysed output

Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.

Frequently asked questions

How are attributes shown?

As keys prefixed with an at-sign on the element object.

What about repeated elements?

They collapse into arrays automatically.

Are namespaces preserved?

Prefixes appear verbatim in key names; no URI resolution.
