JSON to XML Converter
Convert JSON objects into valid, formatted XML.
Paste your JSON payload into the box to instantly convert it into a structured, well-formed XML document. The tool automatically handles the complex structural differences between the two formats, such as dynamically wrapping JSON arrays in repeating XML tags and escaping special characters so the XML parser doesn't break.
Processing happens entirely on our secure server during the lifecycle of the web request. Your sensitive configuration data or API responses are never saved to a database, never logged to disk, and never sent to a third-party analytics provider.
How it works
JSON and XML represent data in fundamentally different ways. JSON is built on lightweight key-value pairs and native arrays, while XML uses a strict hierarchical tree of text nodes and attributes. When converting between them, this tool maps JSON keys directly to XML element tags.
Handling Arrays: Because XML does not have a native bracketed array syntax, a standard JSON array like "users": ["Alice", "Bob"] is intelligently translated into repeating XML elements (e.g., <users>Alice</users><users>Bob</users>). If a raw array is provided as the absolute root element of the JSON, it is automatically wrapped in generic <item> tags to ensure the XML remains valid.
Invalid XML Names: XML tags have strict naming conventions: they cannot start with numbers and cannot contain spaces or special punctuation characters. If your JSON contains a key like "123_data", the tool safely normalizes it into a valid XML tag name (e.g., _123_data) so the resulting document remains 100% compliant with standard XML parsers.
Frequently asked questions
How are JSON arrays handled in XML?
JSON arrays are gracefully converted into multiple XML elements sharing the exact same tag name. If the array is nested under a key named "items", you will get repeating <items> tags in the resulting XML output.
What happens to JSON null values?
A JSON null value is converted into a standard empty self-closing XML tag (e.g., <key/>). This preserves the structure of the data without inserting the literal string "null".
Is my corporate API data secure?
Yes, completely. Processing runs entirely in volatile server memory and is securely discarded the precise moment the response is sent. Your JSON is never saved to a persistent database or written to disk.
What is the maximum JSON payload size?
You can process up to 2 MB of JSON data at a single time. Larger files should be processed locally to avoid browser rendering freezes.
Are JSON boolean values preserved?
Yes. Boolean values (true or false) in JSON are converted to the literal strings "true" and "false" as text nodes inside the XML element, since XML has no native boolean data type.
