About JSON to XML Converter
Convert JSON to XML free online — directly in your browser. No upload, no signup, no waiting. Paste your JSON, get XML instantly.
Convert JSON (JavaScript Object Notation) data to XML (eXtensible Markup Language) format with our professional JSON to XML Converter. XML remains important in legacy integrations, enterprise systems, document-oriented workflows, and APIs that still expect hierarchical markup rather than JSON. This tool helps developers, integrators, and data engineers transform modern structured data into XML quickly without hand-writing tags. The converter includes practical options such as custom root element naming, pretty-printing, XML declaration control, attribute prefix handling, and CDATA-related output settings. Those options matter because XML workflows are often opinionated. A destination system may require a specific root wrapper, expect an XML declaration, or rely on a formatting convention that must be followed closely. This tool is especially useful in migration and interoperability projects. You may have JSON from an API response, app configuration, or exported object model but need to send it into an XML-based service, file format, or integration point. Instead of manually building the document structure, you can generate a clean XML starting point and refine it if needed. The history and sample support also make it practical for repeated development work. Teams can test multiple payloads quickly, compare outputs, and reuse recent conversions when refining a system integration. For modern developers dealing with older XML dependencies, JSON-to-XML conversion is one of those frustrating but necessary format shifts. This tool makes that shift faster and much easier to inspect.
Key features
- Configurable XML output. Set root element name, pretty printing, declaration behavior, and related XML generation options.
- Useful for legacy integrations. Helps bridge JSON-native applications into XML-based systems and workflows.
- History and sample support. Makes repeated conversions and test iterations easier when refining integration output.
- Copy and download workflow. Export the generated XML directly into docs, APIs, test systems, or configuration files.
- Built for structured developer payloads. Handles nested data in a way that is useful for practical transformation and integration work.
Common use cases
- Preparing a payload for an XML-based service. Developers can transform JSON app data into a document shape that older services can accept.
- Migrating modern app data into a legacy platform. Teams can reuse existing JSON structures while generating XML for compatibility layers.
- Building example integration docs. Technical writers can create readable XML samples from structured JSON source data.
- Testing schema-oriented export workflows. Engineers can iterate on XML output faster before integrating with the final destination system.
How to use it
- Paste the JSON input — Add the JSON object or array you want to transform into XML.
- Configure XML options — Choose the root element name and output preferences such as pretty printing and declaration behavior.
- Run the conversion — Generate the XML output from the parsed JSON structure.
- Review the XML result — Inspect the generated document and confirm the shape fits the intended workflow.
- Copy or download the XML — Export the result for integration, testing, or documentation purposes.
Examples
Simple object to XML
Input {"user":{"name":"Jane","active":true}}
Output An XML document with a configured root element and nested tags for the `user` object.
API response export
Input A JSON payload from an internal service
Output A formatted XML structure suitable for a legacy partner system.
Custom root wrapper
Input JSON data with root name set to `response`
Output An XML document wrapped in a `<response>` element to match the target schema style.
Troubleshooting
The XML is valid but the target system rejects it
Cause The receiving system may require a specific schema, tag arrangement, or namespace pattern beyond generic XML validity.
Fix Compare the generated output against the exact XML contract expected by the destination platform.
The structure is more nested than I expected
Cause Nested JSON objects naturally become nested XML elements during conversion.
Fix Reshape the source JSON first if you need a flatter XML representation for the destination system.
I am unsure whether to include the XML declaration
Cause Different systems handle XML declarations differently.
Fix Follow the destination system's documentation; include the declaration when required and disable it when the target expects raw XML content only.
FAQ · 05
Why convert JSON to XML?
Many modern apps use JSON internally, but legacy systems, enterprise integrations, and some APIs still expect XML. Converting JSON to XML helps bridge those environments without rewriting the document structure by hand.
What is the root element for?
XML requires a single root element that wraps the document. Many destination systems also expect a specific root tag name, which is why being able to configure it is useful during integration and export work.
Do I need an XML declaration?
Some systems require the XML declaration line such as `<?xml version="1.0" encoding="UTF-8"?>`, while others do not. This tool lets you control whether that declaration is included based on the needs of the destination workflow.
Can all JSON structures map cleanly to XML?
Most common JSON objects and arrays can be converted, but JSON and XML are not identical models. Some structures may need review after conversion, especially when arrays, attributes, or mixed-content expectations matter in the target XML schema.
Should I still validate the XML after conversion?
Yes. A technically valid XML document can still fail if the target system expects a particular schema, namespace, or tag structure. Conversion is a strong first step, but final compatibility still depends on the receiving system's rules.
