How are JSON arrays converted to XML?

Array items become repeated sibling elements with the same tag name as the parent key. For example, an array at key "tools" produces multiple elements inside the parent — which is how every mainstream XML parser handles lists.

What happens with null or boolean values?

Null values produce a self-closing element with a nil attribute, like . Booleans and numbers are converted to their string form inside the tag, matching XML Schema conventions.

Can I change the root element name?

Yes. Use the Root element input to set any valid XML name. The default is "root" when left blank, but most production APIs expect a specific wrapper like Envelope or Request.

Is the output valid XML?

Yes. The converter escapes special characters (&, , quotes) automatically, picks a valid encoding, and produces a single root element. The output parses in every mainstream XML library without modification.

Is my data sent to any server?

No. The conversion runs entirely in your browser. Nothing is uploaded or logged. Open the Network tab in DevTools and you will see zero outbound requests during conversion.

JSON to XML Converter — Convert JSON to XML Online

Turn JSON into well-formed XML directly in your browser. Toova lets you pick the root element name and indentation, handles arrays and null values cleanly, and gives you XML output that any parser will accept — without sending your data anywhere.

Why convert JSON to XML

Plenty of enterprise systems and legacy APIs still expect XML — SOAP services, banking integrations, government APIs, RSS feeds, and a long tail of B2B platforms. Your modern stack speaks JSON, so somewhere in the pipeline you need a bridge. Toova does the conversion in one paste, with a configurable root element and predictable handling of arrays, booleans, and nulls.

Customize the output

Set the root element name to match what the receiving system expects — Envelope, Request, Item, anything. Choose 2-space or 4-space indentation. Arrays expand into repeated sibling elements with the same tag, which is the convention every XML parser understands. Booleans, numbers, and nulls are serialized the way the XML Schema spec recommends, so the output validates against most strict schemas.

Local-only conversion

Toova converts everything in your browser. The JSON is parsed, mapped to XML nodes, and serialized — all without any network call. No upload, no logging, no analytics on the content. The tool works offline after the page loads, which makes it safe for internal payloads and private integration testing.

Frequently Asked Questions

How are JSON arrays converted to XML?: Array items become repeated sibling elements with the same tag name as the parent key. For example, an array at key "tools" produces multiple <tools> elements inside the parent — which is how every mainstream XML parser handles lists.
What happens with null or boolean values?: Null values produce a self-closing element with a nil attribute, like <tag nil="true"/>. Booleans and numbers are converted to their string form inside the tag, matching XML Schema conventions.
Can I change the root element name?: Yes. Use the Root element input to set any valid XML name. The default is "root" when left blank, but most production APIs expect a specific wrapper like Envelope or Request.
Is the output valid XML?: Yes. The converter escapes special characters (&, <, >, quotes) automatically, picks a valid encoding, and produces a single root element. The output parses in every mainstream XML library without modification.
Is my data sent to any server?: No. The conversion runs entirely in your browser. Nothing is uploaded or logged. Open the Network tab in DevTools and you will see zero outbound requests during conversion.
