JSON Beautifier

The JSON Beautifier accepts raw JSON text and returns a well-structured, human-readable representation. It validates syntax against RFC 8259, rejects invalid input, and provides precise error locations to speed debugging.
Core formatting options include pretty print with selectable indentation (2 or 4 spaces), an optional sort-keys mode for deterministic ordering, and a compact minified output. The formatter treats objects and arrays as first-class structures and preserves data integrity.
Audience and value: developers, testers, and API teams gain faster turnarounds during API design, debugging, and documentation. By providing both a readable form and a compact form, it supports code reviews, payload sharing, and automated checks in CI.
Advanced behavior includes recursive key sorting when enabled, consistent output for unchanged inputs, and comprehensive error reporting that identifies the exact character offset or line/column. It does not perform schema validation, focusing strictly on formatting and syntax compliance.
Use cases span REST and GraphQL payloads, test scaffolding, documentation generation, and CI pipelines. The tool outputs both a formatted and a minified version, and exposes clear diagnostics to accelerate development workflows.
