JSON is used in APIs, logs, configuration files, webhooks, and frontend/backend development. Minified JSON can be hard to read, so this tool formats it with indentation and validates syntax errors instantly.
All formatting, validation, key sorting, copying, and file download operations run in your browser. The JSON you paste is not uploaded to a server, which makes the tool useful for private API responses and local debugging.
Is my JSON uploaded to a server?
No. Formatting, validation, key sorting, copying, and file downloads run locally in your browser.
Does sorting keys change array order?
No. Key sorting only sorts object keys. Array item order is preserved.
