JSON to XML Online

Updated 2026-07-09

Convert JSON to XML online for free, instantly in your browser. Paste JSON and SnapTools produces clean, properly indented XML — objects become nested elements and arrays become repeated tags — ready to copy or download. Nothing is uploaded; the conversion runs locally.

XML is still everywhere: SOAP services, RSS feeds, sitemaps, and countless enterprise and legacy systems expect it. This converter lets you take modern JSON data and express it as well-formed XML in a single step, with names sanitized and special characters safely escaped.

// how to use

1 Paste your JSON into the input panel.
2 SnapTools converts it to clean, indented XML as you type.
3 Copy or download the XML for your API, config, or legacy system.

Feeding JSON data into SOAP or XML APIs Generating RSS or sitemap fragments Integrating with legacy enterprise systems Producing XML config from JSON

// faq

Many enterprise systems, SOAP APIs, RSS feeds, and legacy integrations still require XML. Converting lets you take modern JSON data and feed it into those systems.

Each array item becomes a repeated element. Items inside a named array reuse that key as the element name; a top-level array uses <item> elements.

JSON keys with spaces or other characters that aren't valid in XML names are sanitized (e.g. spaces become underscores), and names starting with a digit are prefixed so the output is always well-formed.

Yes — characters like <, >, and & are escaped to keep the XML valid, and Unicode is preserved.

No — conversion happens in your browser, so nothing leaves your machine.
