Bridging Modern JSON and Legacy XML
That SOAP API you’re integrating with doesn’t care about your beautiful JSON. It wants XML with angle brackets and closing tags. And the enterprise ERP system your company’s been running since 2008? XML config files. Your data’s in JSON because every modern tool speaks JSON. But the systems that actually run the business speak XML.
Paste your JSON, set a root tag name, and get well-formatted XML with proper indentation and an <?xml version="1.0" encoding="UTF-8"?> declaration. Object keys become element names, primitives become text content, and arrays wrap their items in parent elements.
Real Integration Scenarios
SOAP API calls. You’ve got structured data in JSON from your modern frontend. The backend service expects SOAP XML. Convert the data here, wrap it in a SOAP envelope, and send it.
Enterprise config files. Spring Boot apps, Java EE configurations, Android manifests — they all use XML. If your source data’s in JSON (from a config management tool or a database export), convert it here and drop it into your config directory.
XSLT transformations. You need to apply an XSLT stylesheet to your data, but XSLT only works on XML. Convert your JSON to XML first, then run the transformation.
Watch out for JSON keys with spaces or leading hyphens — those produce invalid XML element names. Clean up your keys before converting if your target system validates XML strictly. Arrays get wrapped in parent elements using the parent key name for both the wrapper and child elements.
The XML to JSON converter handles the reverse direction. Both tools run entirely in your browser. No data transmission.
