How do JSON arrays convert to XML?

As repeated sibling elements: {"tags":["a","b"]} → a b (conventions vary — some wrap in a parent …). Check what your consumer expects; array handling is where converters differ most.

How to use JSON to XML

Paste your JSON — it must be valid; run the JSON Validator first if unsure.
Read the XML output — keys as tags, arrays as repeated elements, special characters escaped.
Check the consumer's expectations — element names, root wrapper and attribute conventions vary by system.
Copy the XML into your SOAP request, import file or config.

What is JSON to XML?

A JSON to XML converter restructures data from JSON's braces into XML's tags: {"user": {"name": "Ada"}} becomes <user><name>Ada</name></user>. Keys become element names, nesting becomes nesting, arrays become repeated elements, and XML's escaping rules (&, <, >) are applied where JSON needed none.

The need is directional: modern APIs speak JSON, while a durable enterprise layer — SOAP services, RSS, sitemaps, banking and government interfaces, publishing toolchains — still requires XML. When a JSON-producing system must feed an XML-consuming one, this conversion is the bridge.

About the JSON to XML

Paste valid JSON and get the equivalent XML instantly — nested, escaped and ready for whatever legacy or standards-based consumer demands it.

Typical crossings: submitting data from a modern stack to a SOAP or XML-RPC endpoint, filling XML import formats (accounting, ERP, publishing) from JSON exports, producing configuration for XML-configured software (Java ecosystems especially), and generating test fixtures for XML-consuming code from easier-to-write JSON.

The impedance mismatches worth knowing: JSON arrays have no perfect XML twin (they become repeated sibling elements), XML attributes have no JSON equivalent (converters use conventions like @-prefixed keys), and root rules differ — XML requires exactly one root element, so top-level JSON arrays get wrapped. For the reverse direction, the XML to JSON converter mirrors the mapping back.

Frequently Asked Questions

As repeated sibling elements: {"tags":["a","b"]} → <tags>a</tags><tags>b</tags> (conventions vary — some wrap in a parent <tags><tag>…). Check what your consumer expects; array handling is where converters differ most.

They're XML-escaped automatically: & → &amp;, < → &lt;. Unescaped, they'd break the XML — it's the conversion's most important safety step.

XML requires exactly one root element. A top-level JSON array or multiple keys get wrapped in a root (often <root> or <items>) to satisfy the rule.

Not natively — JSON has no attribute concept. Converters use conventions (keys prefixed with @ become attributes) when round-tripping; for one-way conversion, data usually lands as child elements, which most consumers accept.

JSON, almost always — lighter, native to JavaScript, universal in modern APIs. Choose XML when the counterparty requires it (SOAP, RSS, industry standards) or you need XML-specific machinery like schemas (XSD) and XSLT.
