JSON Formatter & Validator
Paste your JSON to validate it live, then format it (indented) or minify it in one click.
Pourquoi utiliser cet outil ?
Malformed JSON is a common source of bugs when working with APIs or config files. This tool validates your JSON as you type, points out the exact error when something is wrong, and lets you pretty-print or minify it instantly. Everything runs in your browser: nothing is sent to a server.
