How to Use

  1. 1 Paste JSON into the input box (or click 'Load sample')
  2. 2 Set a root element name (defaults to 'root')
  3. 3 Pick indent — 0 (minify), 2-space, or 4-space
  4. 4 Toggle XML declaration on/off
  5. 5 Copy the XML output instantly

Features

  • Pretty-printed or minified XML output
  • Configurable root element name
  • Arrays under a key produce repeated elements with that key as the tag
  • Special chars (& < >) auto-escaped to entities
  • Invalid XML element names auto-sanitised (e.g. '123' → '_123')
  • Optional `<?xml version=1.0 ?>` declaration

Why it Matters

Legacy systems still speak XML — SOAP APIs, RSS feeds, Android resource files, Office Open XML, SVG. Most modern data lives in JSON. A reliable converter saves you from writing one-off transform scripts every time you need to bridge an old system to a new one.

Frequently Asked Questions

How are arrays represented in XML?
An array under a key produces repeated elements with that key as the tag name. So `{users: [{name: 'a'}, {name: 'b'}]}` becomes `<users><name>a</name></users><users><name>b</name></users>`.
What happens to invalid XML element names?
JSON keys like '123abc' or 'user-id' aren't always valid XML names. Invalid characters become underscores; names starting with a digit get a leading underscore. So '123' → '_123'.
Does this support XML attributes?
Not currently — every value becomes an element. Convention for attribute mapping (e.g. `@attr` keys) is implementation-specific; we kept the mapping simple.
Why doesn't my XML have any indentation?
Check the Indent setting. '0' (Minify) produces single-line XML. Pick '2 sp' or '4 sp' for pretty-printed output.
