{ } JSON Formatter

JSON (JavaScript Object Notation) is a lightweight text format for storing and transmitting data. It supports key-value pairs, arrays, and nested objects, and is widely used in REST APIs and configuration files.

Common errors include: missing quotes around keys/strings, trailing commas after the last item, using single quotes instead of double quotes, and mismatched brackets or braces.

Minify JSON for production API responses and file storage to reduce file size and improve load times. Use formatted (pretty-printed) JSON for debugging and development.

Standard JSON does not support comments. If you need comments, use JSON5 or JSONC (JSON with Comments). As a workaround, you can add a "_comment" key with a string value.

JSON5 is a superset of JSON that adds comments, trailing commas, single-quoted strings, and unquoted keys. It is used in configuration files (like .eslintrc) but not in standard APIs.
