## Why Convert JSON to XML?

JSON is the standard for modern REST APIs, but many enterprise systems, legacy applications, and industry standards still require XML. Converting JSON to XML bridges modern web services with traditional enterprise infrastructure.

**Enterprise and legacy system integration. **SOAP web services, enterprise resource planning (ERP) systems, and many government and healthcare data exchanges require XML. If your application produces JSON but needs to communicate with these systems, JSON-to-XML conversion is the bridge.

**Industry standard compliance. **Regulated industries use XML-based standards: HL7 for healthcare, XBRL for financial reporting, and ONIX for publishing. Converting JSON data to XML is necessary for compliance with these standards.

**Schema validation support. **XML supports XSD schemas that strictly define and validate data structure. Converting JSON to XML enables schema validation that JSON Schema does not match in widespread enterprise adoption.

**When to keep JSON instead: **For REST APIs, web applications, and modern microservices, JSON is the standard. XML is more verbose and heavier. Only convert to XML when the receiving system requires it.

Enconvert generates well-formed XML server-side. The free tier supports 100 conversions per month with no sign-up required.

| --- | --- | --- |
| Syntax | Curly braces, square brackets | Opening and closing tags |
| Verbosity | Compact | Verbose (2-3x larger) |
| Data Types | Strings, numbers, booleans, null, arrays, objects | Everything is text (types via schema) |
| Schema Validation | JSON Schema (growing adoption) | XSD (industry standard) |
| Comments | Not supported | Supported (<!-- -->) |
| Attributes | No concept of attributes | Elements can have attributes |
| Namespaces | Not supported | Full namespace support |
| API Standard | REST APIs | SOAP APIs |
| Best For | Modern web, REST APIs, JavaScript | Enterprise systems, SOAP, regulated industries |

## FAQ

### Is the XML output well-formed?

Yes. The output includes a proper XML declaration, root element, and correctly nested child elements. Special characters are properly escaped. The output passes standard XML validators.

### How are JSON arrays mapped to XML?

JSON arrays are converted to repeated XML elements with the same tag name. For example, {"items": \["a", "b", "c"\]} becomes repeated item elements within an items parent element.

### Does it handle nested JSON objects?

Yes. Nested JSON objects are converted to nested XML elements, preserving the full hierarchy. The depth of nesting is not limited.

### Is there a file size limit?

The free tier accepts JSON files up to 5 MB with 100 conversions per month — no sign-up or credit card required. The Starter plan ($19/mo) supports 2,000 conversions with 15 MB file limits, the Pro plan ($49/mo) supports 10,000 conversions with 50 MB limits, and the Business plan ($149/mo) supports 50,000 conversions with 150 MB limits.

### Can I automate JSON to XML conversion?

Yes. The Enconvert API supports programmatic conversion for enterprise integration pipelines. Send JSON via the REST API and receive XML output. Integration examples are available in Python, JavaScript, and cURL.
