JSON Tool FAQ
How do I validate JSON?
Paste JSON into the input box and click Validate. The parser checks the content directly in your browser.
Can I minify large JSON payloads?
Yes. Click Minify to remove extra whitespace and reduce payload size for transport or storage.
What does optimize/compress do?
It minifies JSON and reports how many characters were removed compared with pretty-printed output.
Does this tool send data to a server?
No. Formatting, validation, and minification are performed client-side only.
Example input/output
Input: {"user":{"name":"Ada","age":30}}
Output: <root><user><name>Ada</name><age>30</age></user></root>
How it works
This tool recursively converts the JSON tree to XML by treating each key as an element tag name. Array items are wrapped in numbered or repeated elements. The output is indented for readability. Processing runs in your browser.
Common use cases
- Convert JSON API responses to XML for integration with SOAP services
- Transform JSON configuration to XML format for legacy systems
- Generate XML from JSON data structures for document processing
