The JSON formatter turns compact or hard-to-read JSON into an indented structure, validates its syntax and can minify it again for transport. Because processing is browser-local, you can inspect API responses, configuration snippets and sample payloads without sending them to MiluTools.

Debug an API response, Review a configuration file, Prepare a readable code example, and Minify a payload before testing

If validation fails, inspect the first reported error before changing later lines. Trailing commas, single quotes, comments and unquoted property names are common causes of invalid JSON.
