JSON and XML Converter
Convert structured data between JSON and XML in either direction. Legacy systems that speak XML and modern services that speak JSON finally meet in one paste.
Step-by-step guide to the JSON ↔ XML Converter
- Select the direction: JSON to XML or XML to JSON.
- Paste your source document into the input panel.
- Press convert to produce the equivalent document in the other format.
- Copy the result into the system that expects it.
Practical scenarios for the JSON ↔ XML Converter
- Feeding modern API output into legacy XML-based enterprise systems.
- Converting old XML configuration into JSON for newer tooling.
- Testing how a payload survives translation between formats.
- Interoperability work between services with different data expectations.
How the JSON ↔ XML Converter works under the hood
JSON to XML maps object keys to element names, arrays to repeated child elements, and primitive values to text content. XML to JSON parses elements, attributes, and text nodes back into a natural JSON shape. Both conversions validate input first, so malformed documents fail fast with a clear message. The translation runs locally, keeping proprietary payloads private.
What the JSON ↔ XML Converter does not do
Some XML features, such as mixed content or processing instructions, do not map naturally to JSON and may lose nuance in conversion.
Common questions about the JSON ↔ XML Converter
What happens to XML attributes?
They are converted to JSON properties, typically prefixed so they remain distinguishable from child elements.
Does order matter in the conversion?
Element order is preserved where possible, though JSON objects themselves are unordered by specification.
Can I convert large files?
Yes, within browser memory; very large documents may take a few seconds.
