What can this online JSON formatter do?
Paste JSON to format, minify, and validate it directly in your browser, with a tree view on the right. Your data is not sent to the server.
- Format compact or messy JSON into readable, indented output.
- Minify JSON by removing unnecessary spaces and line breaks.
- Validate JSON automatically as the input changes.
- Inspect objects, arrays, and nested fields in a tree view.
