📋JSON Formatter and Validator

Free online JSON formatter

Format, validate, and minify JSON

Paste an API response, configuration file, or debug payload to pretty-print it with readable indentation, minify it for compact transfer, or check whether the JSON is valid.

Explore nested objects with a JSON tree view

The collapsible tree view makes deeply nested objects and arrays easier to inspect. Validation details include the root type, keys or items, depth, nodes, and character count.

JSON stays on your device

Parsing and formatting happen entirely in your browser, so pasted data is not sent to a server. For other formats, try the CSV, JSON, and YAML converter.
