JSON Formatter Code

This tool formats JSON input into a canonical, readable form or a compact version, with optional validation against a JSON Schema. It preserves data fidelity, applies correct escaping, and reports exact error locations when parsing fails. It is intended for developers, QA engineers, and data scientists who work with API responses, logs, or configuration files. The formatter operates purely on JSON syntax and does not execute code or perform cross-format transformations. Unique value lies in precise error reporting, a small AST-like view for tooling, and seamless integration into data pipelines without UI concerns. Core features include pretty printing with configurable indentation, minification, and schema-aware validation; advanced options offer deterministic key ordering hints and Unicode escaping controls. Use cases include preparing sample payloads for documentation, debugging API responses, and enforcing consistency across teams.
