JSON to XML

The JSON to XML Converter transforms your JSON into well-formed XML — mapping keys to elements, arrays to repeated elements, and wrapping everything in a proper root with an XML declaration. Ideal for feeding JSON data into XML-based systems, SOAP services, and legacy enterprise software. Paste, convert, and copy. Free, private, and processed in your browser.

Bridge JSON Data Into an XML World

Your data lives as JSON, but the system you need to talk to speaks XML — a SOAP web service, a legacy enterprise application, an XML configuration format. This converter bridges that gap, translating your JSON structure into valid XML so it can be consumed by anything that expects the older format. It handles the structural translation correctly, so you don't have to hand-write tags.

How to Use It

1. Paste your JSON into the input.
2. Convert to mapped, nested XML.
3. Copy the XML for your XML-based system.

How JSON Maps to XML

The translation follows clear rules: each JSON key becomes an element, its value becomes that element's text content, nested objects become nested elements mirroring the hierarchy, and the converter adds the standard <?xml version="1.0" encoding="UTF-8"?> declaration. The output is properly indented and ready to use.

The Root Element Requirement

Here's a structural rule worth understanding. XML requires exactly one top-level root element, but JSON allows multiple top-level keys or even a bare array. So the converter wraps your entire structure in a single root tag — usually configurable — to produce valid XML. This wrapper isn't optional; without it, the XML would be malformed.

How Arrays Become Repeated Elements

XML has no array type, so a JSON array is expressed as repeated elements sharing the same tag name. A list of two values under a key produces two elements with that key's name, preserving order and content. It's XML's idiomatic way of representing a collection — different syntax, same data.

An Honest Note on Types and Keys

Two translation details matter. First, XML has no data types: a number becomes <age>30</age> and a boolean becomes <active>true</active> — plain text that your consuming code must interpret, with null typically becoming an empty self-closing tag. Second, JSON keys with spaces or special characters get sanitized (usually to underscores) because XML element names are stricter, so first name becomes first_name. Keep both in mind if your downstream system expects exact types or names.

Free and Private

Conversion runs entirely in your browser, so your data never leaves your device. Paste your JSON, convert it to clean XML, and copy the result — free, with no signup. To go the other direction, use an XML to JSON converter.

JSON to XML FAQs

How do I convert JSON to XML?

Paste your JSON and the tool produces equivalent XML — each key becomes an element, values become the element's text, nested objects become nested elements, and arrays become repeated elements. Because XML requires a single root, the whole structure is wrapped in a root element, and a standard XML declaration is added at the top. Then copy the result.

Why does the output get wrapped in a root element?

Because XML, unlike JSON, requires exactly one top-level root element. JSON can have multiple top-level keys or even be an array, so the converter wraps everything in a single root tag (often called 'root', though it's usually configurable) to produce valid XML. Without this wrapper, the XML would be malformed.

How are JSON arrays converted to XML?

Since XML has no native array type, each item in a JSON array becomes a repeated element with the same tag name. For example, a list under a key becomes several elements sharing that key's name (or a generic tag like ). This preserves the order and all the values, just using XML's repeated-element pattern instead of brackets.

What happens to numbers, booleans, and null?

XML has no built-in data types, so numbers and booleans are written as plain text content — a 30 becomes 30 and true becomes true. Your XML-consuming code has to interpret these as numbers or booleans itself. Null values typically become empty, self-closing elements like .

Why would I convert JSON to XML?

Usually to feed data into systems that require XML. Many enterprise and legacy systems, SOAP web services, and configuration formats (like those used by older Java, Spring, or Maven setups) expect XML rather than JSON. When your data originates as JSON but the destination speaks XML, converting at that boundary is the clean solution.

What if my JSON keys have spaces or special characters?

XML element names can't contain spaces or many special characters, so the converter sanitizes them — typically replacing invalid characters with underscores — to produce valid element names. This keeps the XML well-formed, though it means a key like 'first name' becomes an element like 'first_name', which is worth noting if your downstream system expects exact names.

Does the conversion preserve all my data?

The values and hierarchy are preserved, but be aware of the structural translation: types become text, arrays become repeated elements, and keys may be sanitized. For most data this is a faithful representation. If you need attributes (which JSON doesn't have a native concept of), those require a specific convention or manual editing, since plain JSON keys all become elements.

Is the tool free and private?

Yes. Conversion runs in your browser, so your data never leaves your device, and it's free with no signup. Paste, convert, and copy.
