JSON to XML

The JSON to XML converter transforms JSON objects and arrays into clean, well-formed XML the moment you paste your data. JSON dominates modern web APIs, but plenty of enterprise systems, configuration formats, SOAP services and legacy integrations still expect XML, so a fast and accurate bridge between the two formats removes a tedious manual step from everyday development work.

This tool is built for developers, integration engineers and analysts who routinely move data between services that disagree on format. It walks the entire JSON structure recursively, turning object keys into element names, wrapping array members in repeatable item elements, and escaping the five reserved XML characters so the result is always valid markup you can drop straight into a request body, document or feed.

Everything runs locally in your browser using JavaScript, so even sensitive payloads such as customer records, order data or internal configuration never leave your device or touch a server. You paste JSON, choose the root and item element names you want, pick an indent size, and the formatted XML appears instantly with a clear error message if the JSON cannot be parsed.

Features

• Converts nested JSON objects and arrays of any depth into correctly structured, hierarchical XML elements.
• Lets you set a custom root element name so the output wraps cleanly inside the container your system expects.
• Wraps array members in a configurable item element name so repeated values become repeatable child nodes.
• Escapes the five reserved XML characters automatically so ampersands, quotes and angle brackets never break the markup.
• Offers two-space or four-space indentation so the output matches your project's formatting conventions exactly.
• Includes an optional XML declaration line so you can produce a complete document or a bare fragment as needed.
• Sanitizes invalid characters in keys into safe element names so unusual JSON property names still produce valid XML.
• Runs entirely in your browser with no uploads, accounts or limits, keeping sensitive JSON payloads on your device.

How to use JSON to XML

1. Paste your JSON into the input box, or upload a .json or .txt file containing the data you want to convert.
2. Set the root element name that should wrap the whole document, using a value your target system expects.
3. Choose the item element name used for the members of any JSON arrays so repeated entries are clearly labelled.
4. Pick two-space or four-space indentation and decide whether to include the XML declaration line at the top.
5. Watch the well-formed XML appear instantly in the output panel, updating live as you adjust the options.
6. Copy the XML to your clipboard or download it as a file to use in your request, document or configuration.

Benefits

• Integration engineers feed JSON data into SOAP services and legacy systems that only accept XML payloads.
• Developers generate XML fixtures and sample documents from JSON without hand-writing repetitive markup.
• Analysts reshape API responses into XML for tools, reports and pipelines that consume that format natively.
• Teams migrating between systems convert stored JSON into XML records during one-off data transformation tasks.
• Anyone handling private data can convert payloads locally without uploading sensitive information anywhere.
• Engineers prototype quickly by pasting JSON and instantly seeing the equivalent XML structure side by side.

JSON and XML describe the same kinds of data in different ways, and converting between them is mostly about mapping keys to element names. This tool keeps that mapping predictable: each object becomes a set of nested elements, each array becomes a parent element containing repeated item nodes, and primitive values become the text content of their element. The result is the structure most XML consumers expect.

Because XML element names cannot contain spaces or many punctuation characters, any JSON key that would be illegal as a tag is sanitized into a safe equivalent automatically, and names that would otherwise start with a digit are prefixed so they remain valid. This means even messy, machine-generated JSON keys produce markup that parsers accept without complaint.

All conversion happens locally in your browser, so nothing you paste or upload is transmitted, logged or stored anywhere. The converter is accurate for any valid JSON, but malformed input such as a trailing comma or an unquoted key will produce a parse error describing the problem, which you can fix in the source and convert again immediately.
