Data & Code Converters

XML to JSON Converter (JSON to XML Online)

Instant on-device convert

Translate XML and JSON locally. Element attributes become @prefixed keys and character data uses #text so structure survives the round trip.

Direction

All conversion runs locally in your browser—nothing is uploaded.

  • tag

    Element name

    XML tag that becomes a JSON property (or vice versa).

  • @attr

    Attribute

    XML attribute stored under an @-prefixed JSON key.

  • #text

    Text node

    Character data when an element has attributes or child elements.

When to use this XML ↔ JSON

Common use cases

  • Transform sample payloads without uploading sensitive data
  • Move between JSON, CSV, YAML, XML, or Base64 quickly
  • Clean developer workflow conversions in the browser

Localized examples

  • UTF-8 text and spreadsheet-friendly CSV output
  • Config file migrations for local projects

What you get

  • Client-side conversion — files stay private
  • Bidirectional transforms where supported
  • No sign up, instant result

How to Convert XML ↔ JSON Step-by-Step

  1. 1Select XML → JSON or JSON → XML.
  2. 2Paste XML/JSON or drop a matching file.
  3. 3Convert to generate the opposite format.
  4. 4Download the output or copy it to your clipboard.
  5. 5Validate nested tags or object keys if you see a parse error.

Governing formula

XML(DOM) ⇄ JSON({ tag, @attrs, #text })

XML is walked into a JSON tree. Attributes are stored as @name keys; mixed content uses #text. JSON → XML reverses the mapping into well-formed UTF-8 XML.

Use the defaults, then adjust one input at a time to see the result update instantly—no sign up.

Variable definitions

  • tag

    Element name

    XML tag that becomes a JSON property (or vice versa).

  • @attr

    Attribute

    XML attribute stored under an @-prefixed JSON key.

  • #text

    Text node

    Character data when an element has attributes or child elements.

  • Invalid XML surfaces a clear parse error before conversion.
  • Array-valued siblings become repeated XML elements.

Frequently Asked Questions

Attributes become keys prefixed with @ (for example @id). Text content uses #text when siblings or attributes are also present.

Very usable on mobile. Would love a save/export option later, but the math feels solid.

The FAQ section answered my questions before I even had to search. Smooth dark mode too.

Simple inputs, clear outputs. This replaced three bookmarks I used to juggle.
