Da JSON a XML
JSON and XML are both data formats. Some systems, APIs and feeds still require XML, so converting JSON to XML saves manual rewriting.
Open JSON to XML →Visualizzatore JSON
A JSON viewer makes large or minified JSON readable by showing it as a structured tree you can expand and collapse.
Open JSON Viewer →Formattatore JSON
A JSON formatter adds line breaks and indentation to compact JSON so it is easy to read and debug.
Open JSON Formatter →Validatore JSON
A JSON validator checks whether your JSON follows the correct syntax and points out problems like missing commas, quotes or brackets.
Open JSON Validator →How to Use Our Development Tools
- Paste your code or data into the input box (or upload a file where supported).
- Choose any options such as indentation.
- Click the action button.
- Copy or download the output.

Development Tools – Worked Example
Example: an API returns one long line of JSON and the app crashes. Pasting it into a JSON Validator reveals a trailing comma on line 1; after removing it, the formatter shows clean, indented data that is easy to debug.
