About the JSON to XML Converter
Overview
JSON and XML are both used to represent structured data. APIs often use JSON; legacy systems or SOAP may use XML. This tool converts JSON input to XML so you can feed JSON data into XML-based pipelines or validate the structure. The conversion follows common rules: JSON objects become XML elements, arrays become repeated elements, and primitive values become text content or attributes as appropriate. For the reverse (XML to JSON) you would need a dedicated tool. For formatting or validating JSON only, use the JSON Formatter; for structured data in web pages use the Schema.org generator.
When to use it
Use the converter when you have JSON from an API or file and need to produce XML for a system that expects XML (e.g. legacy integration, EDI, or some CMS). Use it to quickly test how a JSON structure maps to XML. For JSON-only tasks (format, minify, validate) use the JSON Formatter. For generating or validating JSON-LD structured data for SEO use the Schema.org tool. We do not store your JSON or XML; conversion runs in your session.
How to use it
Paste your JSON into the input area. Click Convert. The tool parses the JSON and produces XML in the output area. If the JSON is invalid (e.g. trailing comma, wrong quotes), an error message appears and the output is not updated. Use Copy to copy the XML result. Clear resets input and output. Conversion is done in a single request; we do not store or log the content. For very large JSON (e.g. megabytes), consider splitting or using a local script to avoid timeouts.
Tips
JSON key names become XML element names; ensure they are valid XML names (no spaces, no leading numbers). Nested objects and arrays are converted recursively. For consistent XML naming you may need to post-process (e.g. namespace, root element name). Validate your JSON first with the JSON Formatter if you get parse errors. For web page structured data (Organization, FAQ, etc.) use the Schema.org tool to generate JSON-LD; this converter is for general JSON to XML transformation.
Common mistakes
Invalid JSON (trailing comma, single quotes, unescaped newlines) will cause conversion to fail. JSON keys that are not valid XML names (e.g. starting with a number, containing spaces) can produce invalid XML. Expecting exact round-trip (JSON to XML to JSON) may not preserve types or order in all cases. Do not paste sensitive credentials; we do not store but avoid exposing secrets in shared environments. For JSON formatting or validation only use the JSON Formatter; for SEO structured data use Schema.org.
