JSON Validator & Beautifier

JSON (JavaScript Object Notation) is a lightweight text format for exchanging structured data between systems. It is the dominant format for REST APIs, configuration files, and NoSQL document stores. Even small syntax errors — a missing comma, an extra bracket, or a single-quoted string — render an entire JSON document unparseable. Debugging these errors in raw minified payloads is tedious; a validator highlights the exact location of the problem. Beautification (pretty-printing) adds consistent indentation to minified JSON, making nested structures readable at a glance. This tool handles both tasks simultaneously.
