Is my JSON data uploaded anywhere?

No. Formatting and validation run entirely in your browser — safe for API keys and private payloads.

What's the difference between Format and Minify?

Format adds indentation and line breaks for humans to read. Minify strips all whitespace for the smallest file size in production.

About this tool

Almost every API speaks JSON, and almost every developer has stared at a single-line JSON blob trying to find a missing comma. DrokyAi's JSON formatter pretty-prints any valid JSON with clean 2-space indentation, validates broken JSON with precise error locations, and minifies formatted JSON down for production payloads. It also reports useful stats — object depth, key counts and size before/after. Because parsing happens in your browser, you can safely inspect responses containing tokens, personal data or internal IDs without sending them to a third-party server.
