Convert JSON to XML

When a consumer needs XML but your data lives as JSON, Convert JSON to XML builds valid, readable markup in one step. Object keys become elements, scalar values become text, arrays produce repeated elements, and @-prefixed keys can become attributes.

The converter never guesses: choose the root element name, control how attributes are signalled, and pick compact or prettified output. The formatted result is valid XML that validates cleanly and can be round-tripped with the XML to JSON tool. Processing happens entirely in your browser.

• Object-to-element mapping: every key becomes a child element in document order.
• Array-to-repeat mapping: JSON arrays become repeated sibling elements, the XML-native shape.
• Optional attribute generation: @-prefixed keys become XML attributes with a configurable prefix.
• Scalar text content: strings, numbers and booleans become escaped element text.
• Custom root element name: pick the tag that wraps the document.
• Prettified by default: readable, indented XML for review.
• Compact mode: one-line output for payloads and embeds.
• Valid output: generated XML is well-formed by construction and passes the validator.
• Copy, download or print: take the XML anywhere.
• Private by design: local conversion, nothing uploaded.

1. Paste your JSON or load it from a file.
2. Set the root element name for the outer tag.
3. Choose attribute handling — enable @-key attributes and set the prefix if needed.
4. Pick prettified or compact output.
5. Copy or download the XML, or print it to PDF.

Example 1 — Downstream XML integrations. A billing system or warehouse partner accepts only XML. Convert your JSON records with the root element named to match their contract, and feed them directly.

Example 2 — Configuration files. JSON configs converted to XML slot into legacy frameworks that read XML natively, with attributes carrying metadata and elements carrying content.

Example 3 — Data exchange. Converting JSON exports to XML preserves the structure in a format older consumers still understand, and the output validates cleanly.

Example 4 — Round-trip verification. Convert JSON to XML, then use the XML to JSON tool on the result. Matching shapes confirm your mapping rules before you commit to them.

• Legacy-friendly output — XML where XML is required.
• Deterministic mapping — keys to elements, arrays to repeats, @ to attributes.
• Clean and valid — prettified, well-formed output by construction.
• Attribute control — metadata as attributes when you want it.
• Free and private — local conversion, no sign-up.
